WWDC 2020 세션 노트
감사합니다 ?
지난 몇 년간 WWDC 세션 노트는 매우 성공적 이어서이 형태의 WWDC 세션 요약을 계속하기로 결정했습니다. 기여, 피드백, 지원 및 내 세션 노트를 읽어 주셔서 감사합니다.
소개
일반적으로 50 분 세션 비디오를 보는 대신 총알 포인트를 읽는 것이 훨씬 빠릅니다. 그런 다음 흥미로운 것을 발견하면 여전히 볼 수 있습니다.
예외적으로 언급 할 수있는 세션은 ★를 사용하여 강조됩니다.
이것은 모든 비디오를 혼자서 보는 데 많은 노력을 기울이기 때문에 진행 중입니다. 따라서 참을성 있거나 문제를 열어주십시오. 다음에보고 싶은 세션에 어떤 세션에 주목하십시오 :)
기부금
내가 뭔가 잘못되었거나 개선을 제안하는 경우 PR을 제출하십시오. 기여하고 싶다면 Contributing.md를 살펴보십시오.
메모의 전반적인 품질에 기여하고 개선 한 모든 사람과 목록에 완전한 메모를 추가 한 사람들에게 감사드립니다.

Swiftui의 데이터 필수품
https://developer.apple.com/wwdc20/10040
발표자 : Curt Clifton, Luca Bernardi, Raj Ramamurthy
- 시작하기
- 항상 다음 질문을합니다.
- 내 견해는 어떤 데이터가 필요합니까?
- 이 날짜를 어떻게 조작 할 것인가?
- 데이터는 어디에서 나옵니까?
- 데이터 만 표시하는 불변의보기에는 속성 만 포함합니다.
- 자체 구성 객체 에서 여러 속성을 가져옵니다
- 구성 객체는 상태를 돌연변이하기 위해 함수를 포함 할 수 있습니다.
-
@State private var config: ConfigObject() 사용하여 config 변경 후보기를 다시 렌더링합니다. -
@Binding var config 사용하여 공유하여 단일 구성 객체를 통해 부모와 서브 뷰를 통신하도록하십시오. - 달러 기호를 사용하여 IT를 참조로 표시하여
config 전달하십시오 : SubView(config: $config)
- ObservableObject를 사용한 데이터 모델링
- 클래스 제약 프로토콜 (참조 유형에 의해서만 채택 가능)
- 수퍼 커스텀 동작을 달성하는 데 사용할 수 있으며 예를 들어 서비스 또는 서버로 데이터를 뒷받침합니다.
-
var objectWillChange: Self.ObjectWillChangePublisher { get } - 데이터 수명주기를 관리하고 , 부작용을 처리하고 , 기존 구성 요소와 통합하는 데 사용
- 당신의 진실의 원천이 될 것입니다
- 전체 데이터 모델 일 필요가 없습니다. 모델이 복잡한 경우 여러 관측 가능한 개체로 분할하십시오.
- 데이터 모델이 간단한 경우 모든보기에 단일 ObservableObject를 사용하십시오.
- ObservableObject의 속성을 표시하면, 귀하의 견해는
@Published var progress: Double - ObservableObject 종속성을 만드는 방법은 무엇입니까?
-
@ObservedObject-
@ObservedObject var config: Configuration - 당신은 당신의 관점 이외의 개체 소유권을 관리해야합니다.
- ObservableObject의 모든 값 유형 속성에 바인딩을 작성하여 EG
$config.isFinished 로 전달하여 Toggle 컨트롤을 자동으로 업데이트하도록합니다.
-
@StateObject- Swiftui는 ObservableObject를 소유합니다
- 창조/파괴는 View의 수명주기와 관련이 있습니다
- 바디가 달리기 직전에 인스턴스화
-
@published var image: Image property가 포함 된 ImageLoader: ObservableObject 를 구현하려면이를 사용하십시오. -
@StateObject 변경 될 때마다보기가 다시 렌더링되어 이미지로 채워집니다.
-
EnvironmentObject- Swiftui에서는 일반적으로 많은 모듈 식 하위보기의 계층 구조가 있습니다.
- ObservableObject의 주위를 통과하여 많은 보일러 플레이트를 피하기 위해
.environmentObject(...) - 계층 구조의 어느 관점에서든 변경 사항은 다른 관점에 반영됩니다.
- Swiftui 성능 고려 사항
- 느린보기 업데이트를 피하십시오
- 예를 들어 파견이없는 이니셜 라이저를 저렴하게 만듭니다
- 몸을 순수한 기능으로 만드십시오
- 가정을 피하십시오
- 새로운 이벤트 소스 :
onChange , onOpenURL , onContinueUserActivity 메인 스레드에서 실행
- 누가 데이터를 소유합니까?
- 공통 조상에서 데이터를 공유하십시오
-
@StateObject 활용합니다 -
App 에 글로벌 데이터를 배치하고 View 계층 구조를 전달하십시오. 그것으로 변경 사항은 앱의 모든 장면 (인스턴스/창)을 다시 렌더링합니다. - 새로운 2020 : 앱 재시작에 대한 데이터 지속성을 제공하고 진실의 원천으로 사용할 수있는 속성 포장지
-
@SceneStorage- Swiftui가 관리하는 읽기/쓰기 데이터를위한 Scene Per Speagity 래퍼
- 뷰 데이터에 대한 가벼운 저장
- 컬렉션 뷰를 채우는 데 사용하십시오
-
@AppStorage- app-scoped Global Storage,
UserDefaults , usable alleere (app/view)를 사용하여 지속 - 설정을 저장하는 데 적합합니다
-
@AppStorage("amountOfGold") private var amountOfGold = 5000 - 속성이 변경 될 때마다 자동으로 읽기/쓰기

Eliminate animation hitches with XCTest
https://developer.apple.com/wwdc20/10077
Presenter: Tanuja Mohan
- Hitch: A frame appears on screen later than expected
- VSYNC: Time the screen swaps the frame onto the display
- Hitch time: Time in ms that a frame is late to display
- Hitch ratio: Hitch time in ms per second for a given duration
- Apple doesn't use frames per second (fps) since:
- 60 or 120 fps is not always the desired target
- Display may intentionally not be updated
- Target frame rate may intentionally be lower than possible
- Hitch ratio is always comparable across tests, following ratios are recommended:
- Good: < 5ms/s
- Warning: 5..10ms/s - users will start recognizing hitches
- Critical: >10ms/s
- Can be measured using
XCTestMetrics and unit tests or for production apps using MetricsKit and Xcode Organizer -
XCTOSSignpostMetric gives you the following when using an animation os_signpost interval:- 지속
- Total count of hitches
- Total duration of hitches
- Hitch time ratio
- Frame rate
- Frame count
- Specify an animation os_signpost interval by:
-
os_signpost(.animationBegin, log: logHandle, name: "performanceAnimationInterval") -
os_signpost(.end, log: logHandle, name: "performanceAnimationInterval")
- UIKit has pre-defined metrics:
-
XCTOSSignpostMetric.navigationTransitionMetric -
XCTOSSignpostMetric.customNavigationTransitionMetric -
XCTOSSignpostMetric.scrollDecelerationMetric -
XCTOSSignpostMetric.scrollDraggingMetric
- Application state can be reset to avoid tests influencing themselves:
XCTMeasureOptions().invocationOptions = [.manualStop] - Listen to a live testing session at 8:15
Why is my app getting killed?
https://developer.apple.com/wwdc20/10078
Presenter: Andy Aude
- Most common reasons why apps can be terminated in the background
- 충돌
- Segmentation fault
- Illegal instruction
- Asserts and uncaught exceptions
- CPU resource limit
- High sustained CPU load in background
- Energy Exception Report
- Xcode Organizer
-
MXCPUExceptionDiagnostic
- Reports contain call stack points out hotspots in code
- Consider moving work into
BGProcessingTask
- 지키는 개
- Long hang during key app transitions
-
application(_:didFinishLaunchingWithOptions:) -
applicationDidEnterBackground(_:) -
applicationWillEnterForeground(_:)
- These transitions have a time limit on the order of 20 seconds
- Terminations are disabled in Simulator and in the Debugger
- Eliminate deadlocks, infinite loops, synchronous work
- Report available via
MXCrashDiagnostic
- Memory limit exceeded
- App using too much memory
- Same limit for foreground and background
- Use Instruments and Memory Debugger
- Keep in mind older devices
- Memory pressure exit (jetsam)
- Not a bug with your app
- Most common termination
- System freeing up memory for active applications
- Reducing jetsame rate
- Aim for less than 50MB in background
- Upon background flush state to disk, clear out image views, drop caches
- Recovering from jetsame
- Save state upon entering background
- Adopt UIKit State Restoration
- User should not realize app was terminated
- Background task timeout
-
UIApplication.beginBackgroundTask(expirationHandler:) -
UIApplication.endBackgroundTask(_:) - Failure to end the task explicitly result in termination
- Counts exposed via
MXBackgroundExitData - Preventable
- Use the named variant of the UIKit API
beginBackgroundTask(withName:expirationHandler:) - Terminations do not occur in Debugger
- New console message in iOS 13.4 ( Background Task DatabaseTransaction was created over 30 seconds ago. In Applications running in the background, this creates a risk of termination. Remember to call
endBackgroundTask for your task in a timely manner to avoid this. )
- Expiration handler
- Implement an
expirationHandler - Call
endBackgroundTask(_:) inside the handler - Do not begin new work
- Do not rely on it exclusively
- Add telemetry at the start and end of each expiration handler
- Inspect
MXMetricPayload
- Check
backgroundTimeRemaining- Only start work if plenty of time remains
- Unsafe to begin tasks with < 5 seconds remaining
- Avoid leaking
UIBackgroundTaskIdentifier
- New MetricKit API (iOS 14)
-
MXBackgroundExitData shows how often these terminations happen providing counts of each termination type-
cumulativeBadAccessExitCount -
cumulativeIllegalInstructionExitCount -
cumulativeAbnormalExitCount -
cumulativeMemoryResourceLimitExitCount -
cumulativeMemoryPressureExitCount -
cumulativeSuspendedWithLockedFileExitCount -

Design for intelligence: Apps, evolved
https://developer.apple.com/wwdc20/10086
Presenter: Mark Mikin
- This is one of those "why" sessions. Why we should build something?
- Intelligent System Experience
- The main idea is to be proactive
- Intelligence is how the OS works with the apps that people use every day to make the "every day" easier for people
- Intelligence is design (it should be viewed as a design practice)
- Living design . 저게 뭐에요?
- The core job of the designer is to help people accomplish something
- One of the key ways a designer can leverage this is by using elements familiar to the user
- People use a signifier or a symbol
- For example, "Share" button. In the case of iOS, almost everyone can easily recognize the "default" share symbol because it consistently gets used across a lot of apps
- Intelligence is a platform convention, it's in a static glyph or icon, like the share button. It's live
- Intelligence manifests itself by adapting to how the system, the platform, conforms to how people use their devices
- Intelligence is expected (people expect their devices and apps to be smart)
- Extensibility
- Intelligence is powered by an app through extensibility
- Apps have actually been evolving over time
- A lot of the technologies built by Apple that are foundational to the intelligence system (starting from App Extensions debuted at WWDC 2014 and ending with App Clips so far)
- It's built to help growing ecosystem of devices and apps
- Intelligence system is built from a foundation of respecting users privacy
- In the next sessions about system intelligence, Apple's team will try to cover it from a few different angles

Design for intelligence: Discover new opportunities
https://developer.apple.com/wwdc20/10088
Presenters: JP Lacerda
- 지능
- Goal to make your Apple products knowing/understanding you
- Achieve and Discover more, Less tedium, Fewer distraction
- System helps you through suggestions from Siri , Shortcuts , Suggestions , Widgets
- Siri / Shortcuts
- Helps you getting things done by a single tap or asking Siri
- Helps you setting up simple and complex operations ran, eg just by your voice
- View shortcuts through the new Siri suggestion Widget displayed just at the right time to you using the new smart stack and on-device intelligence
- Siri suggestions automatically appear at the right place and time, eg restaurant reservations are added automatically to the calendar
- Siri can remind you when it's time to leave right on your lock screen
- Get Siri suggestions in Maps to eg conveniently find your way to the Airport
- Privacy / Analytics
- Apple chose opt-in to enable analytics on your device to help improve their intelligence services
- 예
- 82% of all notification-based check-ins come from suggestions (data from some Airline apps)
- Apps are visible on average 5x more per day via lock screen, sharing suggestion, search or other entry points
- Give your app superpowers
- Think about which entry points are suitable for your app
- Consider how you can measure the impact of intelligence on your app
- Understand intelligence from the users perspective

UICollectionView was built on the separation of concerns between the data, or the "what"; from the layout, the "where" content is being rendered. - For layout, an abstract class is
UICollectionViewLayout , and a concrete subclass is UICollectionViewFlowLayout . - For the presentation, there are
UICollectionViewCell and UICollectionReusableView . - In iOS 13, there are two new components for Data and Layout respectively with Diffable Data Source and Compositional Layout.
- Section snapshot [New in iOS 14]
- Allow data sources to be more composable into section-sized chunks of data.
- Allow modeling of hierarchical data, which is needed to support rendering outline-style UIs.
- Compositional Layout
- 요약
- Compositional Layout was introduced in iOS 13
- Allows us to build rich, complex layouts by composing smaller, easy-to-reason bits of layout together.
- Describes what the layout to look like instead of how the layout ought to work.
- Section-specific layouts to help you build more sophisticated UIs
- Support for orthogonal scrolling sections.
- Lists [New in iOS 14]
-
UITableView -like sections right in to any UICollectionView . - Rich with features you've come to expect from
UITableView , like swipe actions and many common cell layouts. - Easily mix and match Lists with other kinds of layout on a per-section basis.
- Concrete
UICollectionViewListCell , header and footer support - New Sidebar appearance we see in many iPadOS system apps.
- Modern Cells
- Cell registrations
- Simple, reusable way to set up a cell from a view model.
- Eliminate the extra step of registering a cell class or nib to associate it with a reuse identifier.
- Use a generic registration type which incorporates a configuration closure for setting up a new cell from a view model.
- Cell content configurations.
- Standardized layouts for cells similar to what is seen in
UITableView standard cell types. - Can be used with any cell, or even a generic UIView.
- Background configurations.
- Similar to content configurations but apply to any cell's background with the ability to adjust properties such as color, border styles and more.
What's new in Universal Links
https://developer.apple.com/wwdc20/10098
Presenter: Christopher Linn
- Universal Links
- HTTPS URLs that represent your content both on the web and in your app
- Allow to open your app instead of browser
- Enable by adding an entitlement to your app and a JSON file to your web server - creates secure association between both
- Custom URL schemes not recommended anymore - switch as soon as possible
- Support for watchOS
- Same functionalities like on iOS, tvOS and macOS
- Apply entitlement to your WatchKit extension - not your WatchKit App
- Use
[WKExtensionDelegate.handle(_ userActivity: NSUserActivity) -> Void](https://developer.apple.com/documentation/watchkit/wkextensiondelegate/2798966-handle) to handle Universal Links - Use
[WKExtension.shared().openSystemURL(url)](https://developer.apple.com/documentation/watchkit/wkextension/1628224-opensystemurl) to open Universal Links in other apps - Different API on iOS (UIKit) and macOS (AppKit)
- Universal Links in SwiftUI
- Now it is possible to handle Universal Links equally on all platforms
- Handle Universal Links using
.onOpenURL { url in /* ... */ } - Open Universal Links in other apps using
@Environment (.openURL) var openURL; let url = /* ... */; openURL(url)
- Enhanced Pattern Matching
-
* matches zero or more characters greedily -
? matches any one character -
*? matches at least one character -
"components": [{ "/": "/sourdough/?*", "caseSensitive": false }] for case-insensitive pattern matching (macOS Catalina 10.15.5 and iOS 13.5) -
"components": [{ "/": "/中國哲學書電子化計劃/?*", "percentEncoded": false }] for Unicode pattern matching (macOS Big Sur and iOS 14) -
"defaults": { "percentEncoded": false, "caseSensitive": false } to specify defaults for all components (macOS Big Sur and iOS 14)- Apply
defaults to "details" (includes app IDs and components) or only to "components" to match all elements of the respective arrays
- Substitution Variables
- Named lists of substrings to match against
- Names can contain anything but
$ , ( , ) - Names are always case sensitive in patterns
- Values can contain
? and * but no other substitution variables - Values are case-sensitive by default
- Available today in macOS Catalina 10.15.6 and iOS 13.5
- Predefined Substitution Variables
-
$(alpha)* - match upper and lower case letters -
$(upper),$(lower)* - match either upper or lower case letters -
$(alnum)* - match upper and lower case letters including digits -
$(digit),$(xdigit)* - match either digits or hexadecimal digits -
$(region)** - match every ISO region code defined by Foundation: Locale.isoRegionCodes -
$(lang)** - match every ISO language code defined by Foundation: Locale.isoLanguageCodes - Use
"exclude": true to exclude specific patterns - Substitution variables can be used to form different combinations of patterns, eg show different menus for different countries
- 예
{
"appLinks" : {
"substitutionVariables" : {
"food" : [ " burrito " , " sushi " ],
"Canadian food" : [ " burrito " , " poutine " , " tête-de-violon " ]
},
"details" : [{
"appIDs" : [ " ABCDEF.com..example.restaurant " ],
"components" : [
{ "/" : " $(lang)_CA/$(Canadian food)/ " , "percentEncoded" : false }
{ "/" : " $(lang)_CA/$(food)/ " , "exclude" : true }
{ "/" : " $(lang)_$(region)/$(food)/ " }
]
}]
}
}
- Universal Links Workflow
- After download of an app the system checks its entitlements to see if it needs any app-association files, and downloads them
- App association files can now be downloaded in parallel by connecting to an Apple CDN instead of opening one connection per downloaded app
- CDN is dedicated to associated domains
- CDN uses single HTTP/2 connection for all associated domains on a device
- CDN Reduces load on your server
- CDN routes devices to a known-good, known-fast connection
- Alternate Modes for internal domains not reachable from an Apple CDN
- Managed Mode when distributing within your organization (see What's New in Managing Apple Devices (WWDC20))
- System trusted root certificate
- MDN admin must opt-in
- Works using any profile
- Developer Mode when building your app
- Use any SSL certificate
- User must opt-in from
iOS Settings > Developer > Associated Domains Development or for macOS using the command swcutil developer-mode -e true - Only works using a development profile
- Server path for all modes:
https://example.com/.well-known/apple-app-site-association - Specify domains for different modes in the entitlements as
<string>applinks:testing.example.com?mode=developer</string> (or ?mode=managed or ?mode=developer+managed ) in an array under the key com.apple.developer.associated-domains

Presenters: Ada Chan, Luming Yin
- Intro
- App Clips provide entry points to your users to experience your app with minimal friction.
- Use deep-linked navigation to present the App Clip
- User Quest
- User is in a smoothie shop. They see an NFC tag and tap it using the phone.
- An app clip shows up on the phone's lockscreen with summarized detail about that smoothie.
- User taps "open" and a single screen of your app shows up.
- User can then proceed to the payment via Apple Pay.
- 활성화
- Tapping NFC tags or scanning QR codes - they're just deep links after all (a URL)
- Maps and Siri Nearby Suggestions (for registered businesses)
- Smart app banner in your website (shown in Safari and Messages)
- Apple App Clip codes will be introduced later this year (it's a prettified QR code)
- If the user already has the your app installed, following an App Clip link will open the full app instead.
- 설정
- Configure web server and App Clip for link handling
- Web Server: Update the apple-app-site-association file
- App Clip: Add associated domains entitlement and handle NSUserActivity
- Configure App Clip default and advanced experiences on App Store Connect
- Layout requirements:
- Title: 18 chars limit
- Subtitle: 43 chars limit
- 영상:
- Size: 3000 x 2000px
- Aspect Ratio: 3:2
- Format: png/jpg
- Transparency: No
- 모범 사례
- URL mapping is based on most specific prefix match against registered App Clip experience URLs
- Your App Clip must be able to launch using an exact registered URL. 예를 들어:
- App registers https://bikesrental.com/rent instead of https://website.com/rent?bikeID=2
- When receiving https://website.com/rent?bikeID=2, it should be able to deliver the https://website.com/rent App Clip
- App is responsible for parsing the remaining arguments and presenting the specific bike with ID 2
- You can also register a more specific URL if you want to provide a different and more specific App Clip experience for it
- Configure the Smart App Banner to open App Clip (add this if the content of your web page can be delivered as a better and more streamlined app experience)
- Add/update your website's HTML to add the Smart App Banner meta tag
- 시험
- Specify an App Clip URL under the
_XCAppClipURL environment variable to launch App Clip from Xcode - TestFlight - new App Clips section in App Store Connect

Design for location privacy
https://developer.apple.com/wwdc20/10162
Presenter: Rachel Needle
- Today people share precise location data
- In iOS 14, Core Location allowing users to control and share their approximate location
- All kinds of apps will be impacted by this change (even Apple's apps)
- How to adapt the app to work without precise location?
- Prioritize user control
- Give everyone control over their location data they share and respect their preferences
- Don't require precise location
- Replace precise data with approximate where possible
- Identify where else you use precise location and remove non-essential uses of precise location
- Build trust through transparency
- Communicate with people about what data your app uses and how that data is used
- Make status easy to access
- Allow users to change their decision
- Offer proportional value
- Only ask for precise location when you really need it
- Request precise location in response to user action
- Position the request close to the value it provides
- Consider checking out these two sessions to get detailed information
- Build trust through better privacy
- What's new in location

https://developer.apple.com/wwdc20/10164
Presenters: Wil Addario-Turner
- Tests can pass or fail, or with
XCTSkip , be marked with an explicit "skip" result. - In Xcode 11.4,
XCTSkip , XCTSkipIf and XCTSkipUnless were introduced to allow skipping tests at runtime. - Call
throw XCTSkip("message") and the test will be skipped. -
XCTSkipIf skips when the expression is true. XCTSkipUnless skips when the expression is false. - Check the results from the test navigator and the test report with the line where the skip occurred, along with a reason explaining why.
Embrace Swift type inference
https://developer.apple.com/wwdc20/10165
Presenter: Holly Borla
- Leveraging type inference
- A type can be inferred by the compiler given the context surrounding a variable or function
- SwiftUI code relies on type inference for reusable views
- A demo is presented showing a SwiftUI component being built using generics
- How type inference works in compiler
- Think of type inference as a puzzle
- It resolves the puzzle by filling in the missing pieces using clues from the source code
- Solving one puzzle can give the compiler more clues on how to solve other puzzles
- Type inference errors
- If a puzzle can't be solved, there's an error in the source code
- During type inference, the compiler will record information about errors in source code
- Compiler uses heuristics to attempt to fix errors in order to continue type inference
- Once type inference is done, the compiler will provide actionable error messages based on collected information (some errors might have auto-fixes)
- Swift 5.3 and Xcode 12 improved error handling a lot, showing more meaningful and reliable error messages
- Using Swift and Xcode to fix compile errors
- The compiler will leave breadcrumbs about what the compiler was doing when it found an error
- This can help you connect the dots between the error you're seeing on the editor and other files in your project
- Hold ⌥ + ⇧ on an error breadcrumb and drag it to the right of the source editor, to open the source editor and the breadcrumbs details side by side

What's new in Swift
https://developer.apple.com/wwdc20/10170
Presenters: Ted Kremenek, Kyle Macomber
- Swift Releases
- Xcode 11.4 - Swift 5.2
- Xcode 12 (beta) - Swift 5.3
- Runtime Performance
- Code Size
- Code size is the part of the app that represents the machine code representation of the app's logic
- Swift 5.3 is below 1.5 times the code size of Objective-C version (based on app that ships with iOS)
- Size difference is inevitable because of Swift safety features
- SwiftUI app binary code size can be reduced by 40% (based on MoviesSwiftUI app)
- Memory Layout
- Comparing models with three properties in Obj-C (
NSUUID , NSString and float ) and Swift ( UUID , String , Float ) - In Obj-C, object variables are just pointers which then hold a pointer to their properties
- Swift's use of value types avoid the need to access values via pointers (UUID and Strings)
- Significant memory benefit because it is allocated directly within array storage (contiguous block of memory)
- Heap memory use comparison: 20kB in Swift 5.1 vs 35kB in Obj-C (400 models in array)
- Swift's Standard Library now is below Foundation in the stack which means it can be used to develop low-level frameworks for Objective-C frameworks where previously C has to be used!
- Diagnostics
- New diagnostics in the Swift compiler result in more precise and actionable errors
- Additional notes in error messages (SwiftUI as an example)
- More info on swift.org
- Code completion
- Much better code completion thanks to improvements in SourceKit
- Code completion for dictionary literals, ternary expressions and more dynamic features like key paths
- Code completion in Xcode 12.0 is 15x faster compared to Xcode 11.5
- Code Indentation
- Improved indentation formatting in chained methods calls, tuples, multiline
if and guards - Improved indentation in SwiftUI as well
- 디버깅
- Debugger now displays the reason for Swift runtime failure traps
- Cross-Platform Support
- Multiple platform support
- Apple Platforms
- Ubuntu 16.04, 18.04, 20.04
- Centos 8
- Amazon Linux 2
- Windows (coming soon)
- Swift on AWS Lambda
- Runtime is open-source and is available on GitHub
- 언어

Explore app clips
https://developer.apple.com/wwdc20/10174
Presenters: James Savage, Luming Yin
- What is an App Clip?
- App Clip Experience URL is required to run App Clips which are parts of your app
- On-demand app experiences
- App Clip Experiences
- App Clip URLs are similar to Universal Links
- Registered using App Store Connect
- Surfaced through user actions via NFC / QR codes / links in Safari or other apps / Apple App Clip codes combine the ease of NFC and visual codes so they can be tapped or scanned
- New App Clip Target in Xcode
- Contains all assets
- Needs to be submitted along with the app for review
- It gets downloaded separately if the app is not installed on user's device
- Should be as small as possible for quick downloads (less than 10MB but with enough assets to load UI quickly)
- Focused user flows - one at a time
- 데모
- Ordering smoothies
- New App Clip target embedded in the application
- Name and bundle ID for App Clip added
- It can build and run with boilerplate code right away
- Add code and resources
-
NutritionFacts dependency added - Create new Assets Catalog as shared assets
- Drag App Icon, Colors and other image assets required for app clip into the shared assets catalog
- Add the required model and view files to App Clip target
- Let go of unwanted Swift files like navigation
- Conditionally compile out the references to files not added to App Clip
- Build Settings > Swift Compiler custom flags > Active Compilation Conditions > Add APPCLIP condition for required schemes.
- Use #if !APPCLIP to compile out unwanted references in Swift code
- Write code for App Clip
- Add required models and views to the new AppClip
- Include existing views in the App Clip's content view
- Technology Overview
- App Clips are built using same UI components as an app
- When launched, it receives
NSUserActivity- Use the URL to identify the type of experience to be handled
- Unlike extensions, App Clip can make use of all iOS SDK APIs
- Note: Access to sensitive data is limited
- Always check if data is available
- New location confirmation API helps get the location quickly without requesting full access
- New API for migrating data from App Clip to main app using shared data container once installed
- App Clip and its local storage will be deleted after period of inactivity
- Can not be launched via Universal Links or custom URL schemes
- Can not include bundle extensions like content blockers
- Device states and transitions
- User scans QR code
- iOS locates, downloads and runs the App Clip
- If the App Clip is not revisited for a while, the App Clip and its data gets deleted
- Treat App Clip data as cache; which can be deleted
- If the App Clip is visited frequently, its lifespan will be extended and data may never be cleared
- When user downloads your app, iOS will automatically migrate the data container and the permissions that were already granted by the user
- iOS still deletes the App Clip and its container after copying the data container to the app
- Other technologies
- Apple Pay
- Notifications
- SwiftUI

What's new in HealthKit
https://developer.apple.com/wwdc20/10182
Presenter: Netra Kenkarey
- 증상
- Developers can now track symptoms in HealthKit, read and write symptom samples
- HealthKit attempted to cover and track a wide range of symptoms (shortness of breath, sleep changes, appetite changes, fever, headache, etc.)
- There are 13 symptom data types in HealthKit
- Electrocardiogram (ECG)
- ECG samples will be available for reading in the latest version of iOS and watchOS
- An ECG sample can be read as an
HKElectrocardiogram (it represents a waveform as a series of voltage values) - ECG sample has important properties that describe the measurements
- classification (
HKElectrocardiogram.Classification )- Apple Watch will give the result of the recording in the form of a classification
- The classification is divided into 2 types
- Sinus Rhythm (heart is beating in a uniform pattern)
- Atrial fibrillation (form of irregular rhythm, user should probably go see their doctor)
- If Apple Watch is unable to determine the ECG result, either due to a low or a high heart rate or due to any other reason, the result is considered inconclusive
- symptomStatus (
HKElectrocardiogram.SymptomsStatus )- It tells if the user associated a symptom with this ECG (eg heartburn, tightness in the chest)
- The symptom experienced can be recorded along with the ECG
- averageHeartRage (
HKQuantity? ) - samplingFrequence (
HKQuantity? ) - numberOfVoltageMeasurements (
Int )- It refers to the individual voltage measurements that make up an ECG sample
-
HKElectrocardiogramQuery- To retrieve the individual measurements run the
HKElectrocardiogramQuery - Fetch the ECG samples with any of the HealthKit queries and then initialize the
HKElectrocardiogramQuery with the fetched sample - When this query is executed on the HealthStore, you get the individual voltage measurements back in the ECG and the data handler
- 유동성
- New set of mobility types (available for reading and writing on the latest iOS and watchOS)
- Walking speed and step length
- Walking assymetry and double support percentage
- Stair ascent and descent speed
- Six-minute walk test distance

Get your test results faster
https://developer.apple.com/wwdc20/10221
Presenters: Sean Olszewski
- The Testing Feedback Loop
- Write tests > run tests > Interpret result >if sufficient confidence [ > Next task] else go back to write tests
- Short feedback loops is important because that means you get results from your tests faster, you can ship features to your users faster.
- Real world example: Result bundle from that CI job, which never finished. Due to dead lock, poorly chosen timeout.
- Execution Time Allowance [NEW in XCode 12]
- When enabled, Xcode enforces a limit on the amount of time each individual test can take. When a test exceeds this limit, Xcode will first capture spin dump, then kill the test that hung, restart the test runner, so that the rest of the suite can execute.
- A spin dump shows you which functions each thread is spending the most time in. It's also possible to manually capture spin dump from Terminal using the spin dump command or from within Activity Monitor.
- By default, each test gets 10 minutes. If you need to a specific test or test class, you can use the
executionTimeAllowance API to special case a particular test or subclass. For values under 60 seconds, they'll be rounded up to 60 seconds, the nearest whole minute. - Prevent a test requests unlimited time by enforcing a maximum allowance.
- You can customize the default time allowance and a maximum allowance either via a setting in the Test Plan or through an Xcodebuild option.
- Use
XCTest 's performance APIs to automate testing for regressions in the performance. Use Instruments to identify what parts of your code are slow,
- Parallel Distributed Testing
- Xcode build will distribute tests to each run destination by class. Each device runs a single test class at a time.
- If you're testing logic that is device or OS specific, this can lead to unexpected failures or skipped tests.
