Requesting user Permission for Speech Framework crashes visionOS simulator
When a new application runs on VisionOS 2.4 simulator and tries to access the Speech Framework, prompting a request for authorisation to use Speech Recognition, the application freezes. Using Swift 6. Report Identifier: FB17666252 @MainActor func checkAvailabilityAndPermissions() async { logger.debug("Checking speech recognition availability and permissions...") // 1. Verify that the speechRecognizer instance exists guard let recognizer = speechRecognizer else { logger.error("Speech recognizer is nil - speech recognition won't be available.") reportError(.configurationError(description: "Speech recognizer could not be created."), context: "checkAvailabilityAndPermissions") self.isAvailable = false return } // 2. Check recognizer availability (might change at runtime) if !recognizer.isAvailable { logger.error("Speech recognizer is not available for the current locale.") reportError(.configurationError(description: "Speech recognizer not available."), context: "checkAvailabilityAndPermissions") self.isAvailable = false return } logger.trace("Speech recognizer exists and is available.") // 3. Request Speech Recognition Authorization // IMPORTANT: Add `NSSpeechRecognitionUsageDescription` to Info.plist let speechAuthStatus = SFSpeechRecognizer.authorizationStatus() // FAILS HERE logger.debug("Current Speech Recognition authorization status: \(speechAuthStatus.rawValue)") if speechAuthStatus == .notDetermined { logger.info("Requesting speech recognition authorization...") // Use structured concurrency to wait for permission result let authStatus = await withCheckedContinuation { continuation in SFSpeechRecognizer.requestAuthorization { status in continuation.resume(returning: status) } } logger.debug("Received authorization status: \(authStatus.rawValue)") // Now handle the authorization result let speechAuthorized = (authStatus == .authorized) handleAuthorizationStatus(status: authStatus, type: "Speech Recognition") // If speech is granted, now check microphone if speechAuthorized { await checkMicrophonePermission() } } else { let speechAuthorized = (speechAuthStatus == .authorized) handleAuthorizationStatus(status: speechAuthStatus, type: "Speech Recognition") // If speech is already authorized, check microphone if speechAuthorized { await checkMicrophonePermission() } } }

Bundling OSX installer plugin with productbuild/pkgbuild
I'm trying to create a .pkg installer with productbuild/pkgbuild. But I'd also like to add my custom installer plugin to this. I'm using the following script. I'd like to add my bundle into this script. Since there are no official docs from apple how to do this nor there are a lot of updated resources, here are some things I have tried. adding the following line to Distrubtion.xml <bundle id="pluginid" path="path/to/myplugin.bundle"/> adding component tag to pkgbuild also doesn't do anything --component "path/to/myplugin.bundle" The bundle itself is build with XCode - it is a simple UI for user to type some input in Apple provides documentation for Distribution.xml file, which supports different UI elements but doesn't support text input - docs I have been also looking at this tutorial , it is very outdated but i could still fit it to my needs except the part where the .bundle file needs to be inserted into .pkg. Note - there is no option to view the contents of .pkg file build with pkbuild/productbuild How can i do this process correctly? I would like to link my installer pane plugin to a generic .pkg(with licenses and so on). I'd appreciate any kind of help!

Detect when app window is being moved
Is there a way to detect when your apps (or any app I guess) is being moved by the user clicking and dragging the main window around the desktop at all? I'm trying to find out if there's a way I can find out if a window is being clicked and dragged and whether there's certain triggers to the movement a little bit like shaking an iPhone with Shake to Undo. Thanks

Can SwiftUI TextFields in a List on macOS be marked as always editable?
In SwiftUI's List, on macOS, if I embed a TextField then the text field is presented as non-editable. If the user clicks on the text and waits a short period of time, the text field will become editable. I'm aware this is generally the correct behaviour for macOS. However, is there a way in SwiftUI to supress this behaviour such that the TextField is always presented as being editable? I want a scrollable, List of editable text fields, much like how a Form is presented. The reason I'm not using a Form is because I want List's support for reordering by drag-and-drop (.onMove). Use Case A view that allows a user to compose a questionnaire. They are able to add and remove questions (rows) and each question is editable. They require drag-and-drop support so that they can reorder the questions.

Recently used applications on guardian phone - FamilyControls, DeviceActivityReport
For an iOS app that runs in both child and parent mode across iOS devices. On the child device, with Family Controls enabled using .child permissions via AuthorizationCenter.requestAuthorization(for: .child). Is any way to display a list of recently used apps by the child on the parent (guardian) device, in a privacy-preserving and Apple-compliant way?

How to read a value when tapping a point on a Chart3D
Hi. Chart3D seems to be perfect to visualize a chart on one of my apps. However I would need a way to read the point of a SurfacePlot of a Chart3D that was touched by the user? Something like a Chart .chartOverlay that has a ChartProxy that can convert screen coordinates of the chart in values, but in 3D (maybe using hit testing ). Thanks and best regards. João Colaço

A wrinkle converting a UIKit Document-based app to SwiftUI Document Group
The app I'm converting includes two unique document types. UI-wise they have key similarities (eg contents are password protected) But serialization/model - wise. they are different documents. I have not been able to find any documentation on options for implementing this (eg use a (abstract?) base class derived from FileDocument, with two concrete sub classes? maybe just a single subclass of FileDocument that contains model details for both file types?) Stepping back from implementation options, am I crazy for attempting to use DocumentGroup to create a single app that would need to be able to open/modify/save multiple unique document types? any/all guidance much appreciated.

ViewThatFits and Text Truncation
I'm using ViewThatFits to handle different screen sizes as well as the orientation of the phone. Essentially, I have a smaller view that should only be used in portrait mode on the phone and a larger view that should be used in every other instance. The issue is that both of those views have a Text view that is bound to a String within a SwiftData model. If the String is too long the ViewThatFits considers that when choosing the appropriate subview. This results in a list of items where most items use one view while one or more may use the other view. It would be great if there was a modifier that could be applied to the Text view that resulted in the ViewThatFits ignoring it when determining the appropriate subview. Until such a modifier is available, has anyone come up with creative ways around this?

visionOS NavigationSplitView - Refreshable ProgressView Disappears
Description I've encountered an issue with NavigationSplitView on visionOS when using a refreshable ScrollView or List in the detail view. The Problem: When implementing pull-to-refresh in the detail view of a NavigationSplitView, the ProgressView disappears and generates this warning: Trying to convert coordinates between views that are in different UIWindows, which isn't supported. Use convertPoint:fromCoordinateSpace: instead. I discovered that if the detail view includes a .navigationTitle(), the ProgressView remains visible and works correctly! Below is a minimal reproducible example showing this behavior. When you run this code, you'll notice: The sidebar refreshable works fine The detail refreshable works only when .navigationTitle("Something") is present Remove the navigationTitle and the detail view's refresh indicator disappears minimal Demo import SwiftUI struct MinimalRefreshableDemo: View { @State private var items = ["Item 1", "Item 2", "Item 3"] @State private var detailItems = ["Detail 1", "Detail 2", "Detail 3"] @State private var selectedItem: String? = "Item 1" var body: some View { NavigationSplitView { List(items, id: \.self, selection: $selectedItem) { item in Text(item) } .refreshable { items = ["Item 1", "Item 2", "Item 3"] } .navigationTitle("Chat") } detail: { List { ForEach(detailItems, id: \.self) { item in Text(item) .frame(height: 100) .frame(maxWidth: .infinity) } } .refreshable { detailItems = ["Detail 1", "Detail 2", "Detail 3"] } .navigationTitle("Something") } } } #Preview { MinimalRefreshableDemo() } Is this expected behavior? Has anyone else encountered this issue or found a solution that doesn't require adding a navigation title?

NSTextLists not rendered when NSTextContentStorageDelegate textContentStorage (_:, textParagraphWith:) is implemented
I have a UITextView that contains paragraphs with text bullet lists (via NSTextList). I also implement NSTextContentStorageDelegate.textContentStorage(_:, textParagraphWith:) in order to apply some custom attributes to the text without affecting the underlying attributed text. My implementation returns a new NSParagraph that modifies the foreground color of the text. I based this on the example in the WWDC 21 session "Meet Text Kit 2". UITextView stops rendering the bullets when I implement the delegate function and return a custom paragraph. Why? func textContentStorage(_ textContentStorage: NSTextContentStorage, textParagraphWith range: NSRange) -> NSTextParagraph? { guard let originalText = textContentStorage.textStorage?.attributedSubstring(from: range) else { return nil } let updatedText = NSMutableAttributedString(attributedString: originalText) updatedText.addAttribute(.foregroundColor, value: UIColor.green, range: NSRange(location: 0, length: updatedText.length)) let paragraph = NSTextParagraph(attributedString: updatedText) // Verify that the text still contains NSTextList if let paragraphStyle = paragraph.attributedString.attribute(.paragraphStyle, at: 0, effectiveRange: nil) as? NSParagraphStyle { assert(!paragraphStyle.textLists.isEmpty) } else { assertionFailure("Paragraph has lost its text lists") } return paragraph }

How to move from Share Extension to the main screen

Emulate AppKit NSPopUpButton in SwiftUI
How to make a control that looks and feels as close as possible to NSPopUpButton in SwiftUI, so a Mac user accepts the control as being native Mac UI? Items should have icon and text, I need separators between some items and certain items may be disabled at times, so they should not be selectable. Picker seems to lack some of those features (separators and disabled items), and Menu looks and behaves differently. Any guidance? For now I went with Menu, but find both the "chevron.down" icon at the trailing end as well as the positioning of the menu below the control weird.

In navigationLink closure, FocusState doesn't work in sheet
Hello, I have a question about FocusState, navigationLink and sheet, the code which in navigationLink closure doesn’t work, but work without navigationLink, just like the following code struct ContentView: View { var body: some View { NavigationStack { // this work interView() // this doesn't work NavigationLink { interView() } label: { Text("into interView") } } } } struct interView: View { @FocusState var focusStateA : Int? @State var show : Bool = false @State var text: String = "" var body: some View { ScrollView { VStack { coreView Button("Detail") { show.toggle() } } .sheet(isPresented: $show, content: { coreView }) } } } extension interView { var coreView : some View { VStack { VStack { putdown TextField("hi", text: $text) .focused($focusStateA , equals: 1) } } } var putdown : some View { Button(action: { if focusStateA != nil { focusStateA = nil print("OK") } else { print("It's nil") } }, label: { Text("Put down the keyboard") }) } } and there are some strange phenomena, I must put all view into a scrollview, otherwise, it even doesn’t work without navigationLink This problem has existed in IOS 18, and now in IOS26 still doesn’t be settled, is it a problem or some character?

Is it possible to auto-expand the iOS 26 text selection menu?
I've got a UIKit app that displays a lot of text, and we've completely turned off the system text selection menu and we show our own custom thing instead, to increase discoverability of our text selection actions. But now that iOS 26 can show the full menu even on iPhone, we're looking at switching back to the system menu. It still shows a smaller horizontal-layout menu at first, and then you tap the > symbol to expand to the full menu. Is it possible to jump straight to the full menu, and skip the smaller horizontal one entirely?

UISplitViewController changes behavior of `viewControllers` property on iOS 26
I am attempting to start my application on iOS 26 with Xcode 26. It uses an UISplitViewController that is instantiated through a Storyboard. It uses the "Unspecified" style, which is a holdover from a previous version of iOS. I'm not sure if this is a bug in iOS, or if I am supposed to change it now. The viewControllers property only has the primary view controller on iOS, although it has the primary and detail view controllers on iPadOS. When I start the application on iOS 18.5, it has both primary and detail controllers on both platforms.

Can the macOS Quick Look preview plugin support network capabilities?
I developed a quick look preview plugin on MacOS, and want to add some data tracking to understand user usage. However, I'm encountering errors when using network capabilities within the plugin. I want to confirm whether the preview plugin blocks network capabilities.

Emulate AppKit NSPopUpButton in SwiftUI
How to make a control that looks and feels as close as possible to NSPopUpButton in SwiftUI, so a Mac user accepts the control as being native Mac UI? Items should have icon and text, I need separators between some items and certain items may be disabled at times, so they should not be selectable. Picker seems to lack some of those features (separators and disabled items), and Menu looks and behaves differently. Any guidance? For now I went with Menu, but find both the "chevron.down" icon at the trailing end as well as the positioning of the menu below the control weird.

In navigationLink closure, FocusState doesn't work in sheet
Hello, I have a question about FocusState, navigationLink and sheet, the code which in navigationLink closure doesn’t work, but work without navigationLink, just like the following code struct ContentView: View { var body: some View { NavigationStack { // this work interView() // this doesn't work NavigationLink { interView() } label: { Text("into interView") } } } } struct interView: View { @FocusState var focusStateA : Int? @State var show : Bool = false @State var text: String = "" var body: some View { ScrollView { VStack { coreView Button("Detail") { show.toggle() } } .sheet(isPresented: $show, content: { coreView }) } } } extension interView { var coreView : some View { VStack { VStack { putdown TextField("hi", text: $text) .focused($focusStateA , equals: 1) } } } var putdown : some View { Button(action: { if focusStateA != nil { focusStateA = nil print("OK") } else { print("It's nil") } }, label: { Text("Put down the keyboard") }) } } and there are some strange phenomena, I must put all view into a scrollview, otherwise, it even doesn’t work without navigationLink This problem has existed in IOS 18, and now in IOS26 still doesn’t be settled, is it a problem or some character?

Is it possible to auto-expand the iOS 26 text selection menu?
I've got a UIKit app that displays a lot of text, and we've completely turned off the system text selection menu and we show our own custom thing instead, to increase discoverability of our text selection actions. But now that iOS 26 can show the full menu even on iPhone, we're looking at switching back to the system menu. It still shows a smaller horizontal-layout menu at first, and then you tap the > symbol to expand to the full menu. Is it possible to jump straight to the full menu, and skip the smaller horizontal one entirely?

UISplitViewController changes behavior of `viewControllers` property on iOS 26
I am attempting to start my application on iOS 26 with Xcode 26. It uses an UISplitViewController that is instantiated through a Storyboard. It uses the "Unspecified" style, which is a holdover from a previous version of iOS. I'm not sure if this is a bug in iOS, or if I am supposed to change it now. The viewControllers property only has the primary view controller on iOS, although it has the primary and detail view controllers on iPadOS. When I start the application on iOS 18.5, it has both primary and detail controllers on both platforms.
