The iOS 26 sample below speaks well on iPhone/iPad devices and the iOS simulator. But it does not speak on "Mac (Designed for iPad)", with a voice downloaded via the macOS settings. Instead it issues this warning : Invalid maui voice identifier com.apple.voice.enhanced.en-US.Samantha How to make an iOS app speak on "Mac (Designed for iPad)", with a downloaded voice ? Note : I use iOS 26.5.2 and macOS 26.5.2. I use voices that can be found in System Settings > Accessibility > Read & Speak > System voice. I have checked that "Samantha (Enhanced)" is the "System voice" in the macOS settings. I have checked that the same issue occurs with other voices and other languages. There is no such issue for a voice that never needs to be downloaded. import AVFAudio import SwiftUI @main struct SampleApp: App { var body: some Scene { WindowGroup { SampleView() } } } struct SampleView: View { private var synthesizer = AVSpeechSynthesizer() var body: some View { Button("Speak", action: speak) } private func speak() { let utterance = AVSpeechUtterance(string: "I speak English.") utterance.voice = AVSpeechSynthesisVoice(language: "en") self.synthesizer.speak(utterance) } }

The issue can be reproduced as follows : Launch the iOS 26.5 Simulator. Go to the Settings app. Tap Accessibility. Tap Spoken Content. Turn on Speak Selection. Tap Voices. An empty view gets opened, in which no language can be selected. How can voices be downloaded in the iOS 26.5 Simulator ? Note: There is not such issue in the iOS 18.5 Simulator. Note: There is not such issue in a real iOS 26.5 Device.

To compare the tap areas of two similar buttons, the sample below is run in the preview canvas for an iPhone with iOS 26. Button 1 is outside the toolbar, whereas Button 2 is inside the toolbar. When tapping outside Button 1 near its edge, unexpectedly the action is triggered. When tapping inside Button 2 near its edge, unexpectedly the action is not triggered. Why are the tap areas of similar buttons not similar ? How to make a tap area have the edge of the button ? . . import SwiftUI struct SampleView: View { var body: some View { NavigationStack { Button(action: self.action) { Text("Button 1") } .buttonStyle(.glassProminent) .toolbar { ToolbarItem { Button(action: self.action) { Text("Button 2") } .buttonStyle(.glassProminent) } } } } private func action() { print("Action Triggered !") } } #Preview { SampleView() }

When upgrading an app from iOS 18 to iOS 26, some labels in a toolbar menu get wrapped unexpectedly. The issue can be reproduced through the sample below, which contains this label : "Envoyer une réaction" On iPhone with iOS 18, the label is displayed on 1 line. But on iPhone with iOS 26, the label is displayed on 2 lines. No improvement was obtained through these modifiers : .lineLimit, .frame and .fixedSize . . How to avoid this unnecessary label wrapping that disrupts the readability ? . . import SwiftUI struct SampleView: View { var body: some View { NavigationStack { Color.clear .toolbar { ToolbarItem { Menu { Button(action: {}) { Label("Envoyer une réaction", systemImage: "envelope") } } label: { Image(systemName: "ellipsis") } } } } } } #Preview { SampleView() }

To make a toolbar button that has the maximum width, I proceed as shown below with iOS 26. The appearance of the button is as expected, but its behavior is incorrect. The action is not triggered when tapping within the button, but outside its text. How to make the action triggered when tapping anywhere within the button ? import SwiftUI struct SampleView: View { var body: some View { NavigationStack { Text("") .toolbar { ToolbarItem(placement: .bottomBar) { Button(role: .confirm, action: self.action) { Text("Action") } .frame(maxWidth: .infinity) } } } } private func action() { print("Action Triggered !") } } #Preview { SampleView() }

In the Keynote/Numbers/Pages apps for iPhone, there is a Help menu item for presenting a Help modal view. The view has a button for showing the hierarchical table of contents, and a field for searching the Help pages. How is such a Help modal view built through SwiftUI ? In which format is the Help content stored ?
