Dub Dub Time Machine - Swift Connection, Paris, France, September 2024

Every year, we all get excited about all the new stuff introduced at WWDC, but when we go back to the office, we're hit with the reality that our app supports N-2 - and we won't be able to use all the new shiny for another two years.

What if you could have a reminder two years later of what the (old) new hotness was? Join Ellen as she guides you through the amazing revolutionary world of...iOS 16! Major Swift UI Goodies! TextKit 2! WeatherKit! SwiftRegex! And all sorts of random tiny improvements you can finally actually *use*.

7. Why can't we upgrade?!
8. Existing customer stats
9. Losing new customers on old OS versions
10. ! ♻
18. iOS 16!
19. SwiftUI
20. NavigationView
21. Navigation View
22. NavigationStack NavigationSplitView
23. Better Programmatic Navigation
24. Navigation Stack
25. enum Route: Hashable { case login case signup case home case profile } class NavigationModel: ObservableObject { @Published var navigationPath = [Route]() func handleDeeplinkToProfile() { self.navigationPath = [.home, .profile] } }
26. enum Route: Hashable { case login case signup case home case profile } class NavigationModel: ObservableObject { @Published var navigationPath = [Route]() }
27. struct ContentView: View { @StateObject var navigationModel: NavigationModel var body: some View { NavigationStack(path: self.$navigationModel.navigationPath) { VStack(spacing: 20) { NavigationLink(value: Route.login) { Text("Login") } /" ..$ } .navigationDestination(for: Route.self) { route in switch route { case .login: return TitleView(title: "I am the login page!", navigationModel: self.navigationModel) /" ..$ } } } } }

39. NavigationSplitView
41. AnyLayout
42. @Environment(\.horizontalSizeClass) var horizontalSizeClass var body: some View { if self.horizontalSizeClass =" .compact { return VStack { /$..& } } else { return HStack { /$..& } } }
44. @Environment(\.horizontalSizeClass) var horizontalSizeClass var body: some View { if self.horizontalSizeClass =" .compact { return AnyView(VStack { /$..& }) } else { return AnyView(HStack { /$..& }) } }
46. AnyView -> ☠ Performance
47. AnyLayout -> ! Performance
48. @Environment(\.horizontalSizeClass) var horizontalSizeClass var body: some View { let layout: AnyLayout if self.horizontalSizeClass =" .compact { layout = AnyLayout(VStackLayout()) } else { layout = AnyLayout(HStackLayout()) } return layout { Text("1") Text("2") } }
49. @Environment(\.horizontalSizeClass) var horizontalSizeClass var body: some View { let layout: AnyLayout if self.horizontalSizeClass =" .compact { layout = AnyLayout(VStackLayout()) } else { layout = AnyLayout(HStackLayout()) } return layout { Text("1") Text("2") } }
50. @Environment(\.horizontalSizeClass) var horizontalSizeClass var body: some View { let layout: AnyLayout if self.horizontalSizeClass =" .compact { layout = AnyLayout(VStackLayout()) } else { layout = AnyLayout(HStackLayout()) } return layout { Text("1") Text("2") } }
51. Batteries included: ZStackLayout GridLayout
52. Batteries NOT included: Build your own! (Layout is a public protocol)
53. Making UIKit cells with SwiftUI
54. UIHostingConfiguration
55. let item = items[indexPath.row] cell.contentConfiguration = UIHostingConfiguration { HStack { Text(item.title) Spacer() Image(systemName: "star.fill") .foregroundColor(item.isFavorite ? .yellow : .gray) } }
56. let item = items[indexPath.row] cell.contentConfiguration = UIHostingConfiguration { ItemView(for: item) }
57. ! New SwiftUI stuff
58. Swift Charts

96. Not SwiftUI
97. TextKit 2
98. TextKit 2 (the bane of my existence)
101. NSLayoutManager -> NSTextLayoutManager .layoutManager -> .textLayoutManager NSContentStorage -> NSTextContentStorage
102. .layoutManager -> .textLayoutManager
103. /" NSTextContentStorageDelegate public func textContentStorage( _ textContentStorage: NSTextContentStorage, textParagraphWith range: NSRange) -$ NSTextParagraph?
104. /" NSTextLayoutManagerDelegate public func textLayoutManager( _ textLayoutManager: NSTextLayoutManager, textLayoutFragmentFor location: NSTextLocation, in textElement: NSTextElement) -$ NSTextLayoutFragment
105. TK2 Good ‣ Way better separation of display vs storage concerns
106. TK2 Good ‣ Way better separation of display vs storage concerns ‣ Layout fragments to allow more complex and reusable design choices
107. TK2 Good ‣ Way better separation of display vs storage concerns ‣ Layout fragments to allow more complex and reusable design choices ‣ Handling composed character languages and emoji is much easier
108. TK2 Less Good...
109. Existing UITextView bugs
110. UITextRange <-> NSTextRange <-> NSRange <-> Swift.Range
111. Who Uses What ‣ UITextRange/Location: Selection in UITextView
112. Who Uses What ‣ UITextRange/Location: Selection in UITextView ‣ NSTextRange/Location: Fragments, Layout manager, Text Elements, Text content storage delegate
113. Who Uses What ‣ UITextRange/Location: Selection in UITextView ‣ NSTextRange/Location: Fragments, Layout manager, Text Elements, Text content storage delegate ‣ NSRange: Working with ranges of the underlying NSString or NSAttributedString
114. Who Uses What ‣ UITextRange/Location: Selection in UITextView ‣ NSTextRange/Location: Fragments, Layout manager, Text Elements, Text content storage delegate ‣ NSRange: Working with ranges of the underlying NSString or NSAttributedString ‣ Swift.Range: Working with any Swift.String or Swift.AttributedString you wound up with
115. "Make the selected range bold"
116. "Make the selected range bold" ‣ Make sure NSTextStorage for the UITextView is hooked up to NSTextContentStorage's underlying text storage
117. "Make the selected range bold" ‣ Make sure NSTextStorage for the UITextView is hooked up to NSTextContentStorage's underlying text storage ‣ Get UITextRange of selected text from UITextView
118. "Make the selected range bold" ‣ Make sure NSTextStorage for the UITextView is hooked up to NSTextContentStorage's underlying text storage ‣ Get UITextRange of selected text from UITextView ‣ Convert UITextRange to NSRange
119. "Make the selected range bold" ‣ Make sure NSTextStorage for the UITextView is hooked up to NSTextContentStorage's underlying text storage ‣ Get UITextRange of selected text from UITextView ‣ Convert UITextRange to NSRange ‣ Use NSRange to update underlying NSAttributedString in textContentStorage.contentStorage font to a bold one
120. "Make the selected range bold" ‣ Make sure NSTextStorage for the UITextView is hooked up to NSTextContentStorage's underlying text storage ‣ Get UITextRange of selected text from UITextView ‣ Convert UITextRange to NSRange ‣ Use NSRange to update underlying NSAttributedString in textContentStorage.contentStorage font to a bold one ‣ Have layout elements reload using NSTextRange
121. When should you use TextKit 2?
122. Use TK2: ‣ New Apps
123. Use TK2: ‣ New Apps ‣ Apps without super-complicated text logic that interact with TK1
124. Use TK2: ‣ New Apps ‣ Apps without super-complicated text logic that interact with TK1 ‣ Apps with complicated but well-tested text logic
125. Use TK2: ‣ New Apps ‣ Apps without super-complicated text logic that interact with TK1 ‣ Apps with complicated but well-tested text logic ‣ Apps which want deeper interaction with Apple Intelligence™
127. Save yourself some trouble! ‣ Existing apps with very complex and untested display and/or storage logic
128. Data Scanner View Controller
129. Before ↔ " # $
130. After ! DataScannerViewController
131. Features ‣ Locations of detected data already in view coordinates
132. Features ‣ Locations of detected data already in view coordinates ‣ Items have unique identifiers
133. Features ‣ Locations of detected data already in view coordinates ‣ Items have unique identifiers ‣ Items are placed in reading order in delegate callbacks
134. Features ‣ Locations of detected data already in view coordinates ‣ Items have unique identifiers ‣ Items are placed in reading order in delegate callbacks ‣ Async stream available if you don't need to create UI.
135. Non-UI features!
136. Transferable Protocol
137. Transferable Protocol* * - Kind of for UI but doesn't provide any itself
138. Drag + Drop Copy + Paste Across apps
139. Generic Transferrables ‣ ProxyRepresentation
140. Generic Transferrables ‣ ProxyRepresentation ‣ CodableRepresentation
141. Generic Transferrables ‣ ProxyRepresentation ‣ CodableRepresentation ‣ DataRepresentation
142. Generic Transferrables ‣ ProxyRepresentation ‣ CodableRepresentation ‣ DataRepresentation ‣ FileRepresentation
