I am really stuck. I uploaded my Mac Catalyst app. The binary passes validation beforehand. I submit for review. After being in "waiting for review" for a couple of minutes it is rejected with "invalid binary" and comes back with an email saying "ITMS-90053: This bundle is invalid - The bundle identifier is already in use by a different software package." The only app that is using the same bundle is the IOS version where I added the Mac platform.

My app uses CGEventTapCreateForPid to monitor keyboard events of a corresponding process. My app has already enabled the Accessibility permission, and AXIsProcessTrustedWithOptions returns true. However, CGEventTapCreateForPid returns null. What could be the problem? Does anyone know? I tested and found that if CGEventTapCreateForPid returns null, I can reset the Accessibility permission using tccutil reset Accessibility myapp_bundleid without restarting my app. But my app can still get the permission through AXIsProcessTrustedWithOptions

Starting with the macOS version 14.x.x and TextKit1, selecting multiple lines of text triggers a text replacement bug: some of the text on one of the selected lines inadvertently replaces a portion of the selected text. For example, the bug is exhibited when selecting the following lines: Carnaroli, Maratelli, or Vialone Nano are best Vialone Nano cooks quickly – watch it! It also absorbs condiments nicely. Avoid Baldo, Originario, Ribe and Roma To trigger the bug, select the three line paragraph using either the cursor or shift with arrow keys. Notice that a portion of the selected text was replaced. Command-Z to undo will allow you to repeat the undesired behavior. In this case, "e Nano cooks quickly - " is replaced by "Baldo, Originario, Ribe." This does not occur with all strings or selected strings, but in cases where it does occur, it is perfectly reproducible. It does not occur on iOS. Pasteboard contents are irrelevant. After triggering the bug repeatedly, at some point it stops occurring. Why does this bug occur? How can it be fixed? Here is some sample code to reproduce the issue. @end @implementation TestNoteViewController - (void)viewDidLoad { [super viewDidLoad]; [self createTextView]; } - (void)createTextView { NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:self.note.text attributes:nil]; NSTextStorage *textStorage = [NSTextStorage new]; [textStorage appendAttributedString:attrString]; CGRect newTextViewRect = self.view.bounds; // Create the layout manager NSLayoutManager *layoutManager = [NSLayoutManager new]; [textStorage addLayoutManager:layoutManager]; // Create a text container NSTextContainer *container = [[NSTextContainer alloc] initWithSize:CGSizeMake(newTextViewRect.size.width, CGFLOAT_MAX)]; [layoutManager addTextContainer:container]; // Create and place a text view UITextView *textView = [[UITextView alloc] initWithFrame:newTextViewRect textContainer:container]; [self.view addSubview:textView]; textView.translatesAutoresizingMaskIntoConstraints = NO; UILayoutGuide *safeArea = textView.superview.safeAreaLayoutGuide; [textView.leadingAnchor constraintEqualToAnchor:safeArea.leadingAnchor].active = YES; [textView.trailingAnchor constraintEqualToAnchor:safeArea.trailingAnchor].active = YES; [textView.topAnchor constraintEqualToAnchor:safeArea.topAnchor].active = YES; [textView.bottomAnchor constraintEqualToAnchor:textView.superview.bottomAnchor].active = YES; } @end

For some reason, I have to build my iOS app project on target My Mac(Designed for iPhone) instead of using Mac Catalyst. Now I want to access these window buttons, is there any possible way to do that? or print current view/components whatever it is while clicking button?

Hello, We've an iOS application that can be launched on macOS (with the "designed for iPhone" available with Catalyst). This application request authorization on MPMediaLibrary and play MPMediaItem with an audio player. After accepted, the authorization status is well flagged as .authorized I can browse all MPMediaItem without issue and display them in my app. But, when it comes the time to convert the MPMediaItem file's URL in AVAudioFile with: AVAudioFile(forReading: fileURL) We got 2 warnings in the console: ExtAudioFile.cpp:211 about to throw -54: open audio file AVAEInternal.h:109 [AVAudioFile.mm:135:AVAudioFileImpl: (ExtAudioFileOpenURL((CFURLRef)fileURL, &_extAudioFile)): error -54 We finally get an exception with this error: Error Domain=com.apple.coreaudio.avfaudio Code=-54 "(null)" UserInfo={failed call=ExtAudioFileOpenURL((CFURLRef)fileURL, &_extAudioFile)} This working perfectly on iOS and iPadOS, but with Catalyst we always got this error whatever the audio (from iTunes library) we try to play. Why do we have this permission issue only on macOS ? There is something different to do to get permission on macOS ? thanks !

I recently updated to macOS Sonoma 14.4 and now UIDevice.current.batteryLevel is always 0. Code to reproduce: import SwiftUI struct ContentView: View { @State private var monitoringEnabled = UIDevice.current.isBatteryMonitoringEnabled; @State private var batteryLevel = UIDevice.current.batteryLevel; var body: some View { VStack { Text("Battery Monitoring Enabled: " + String(monitoringEnabled)) Text("Battery Level: " + String(batteryLevel)) Button("Toggle Monitoring") { monitoringEnabled = !monitoringEnabled; UIDevice.current.isBatteryMonitoringEnabled = monitoringEnabled; batteryLevel = UIDevice.current.batteryLevel; } } .padding() } } Run the above on a macOS 14.4 target, click "Toggle Monitoring", and you'll see battery level is reported as 0: I also see the following error in my app logs when running on macOS 14.4: Error retrieving battery status: result=-536870207 percent=0 hasExternalConnected=1 isCharging=0 isFullyCharged=0 This code displays the expected battery level when running on an actual iOS device:

I am adding Group Activities integration with a MacCatalyst app. I have added the Group Activities entitlement in Xcode. I also checked the entitlements with : codesign --display --entitlements :- I can see the entitlement : <key>com.apple.developer.group-session</key><true/><key> The feature work fine on iPadOS but when I run it on MacOS, the GroupActivitySharingController is not loading properly. I get the following error messages: Cannot run query EXQuery: extension point com.apple.groupactivities platforms: 6 with error: (null) Failed to lookup extension with query EXQuery: extension point com.apple.groupactivities platforms: 6 on <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to fetch config for hostViewController <_GroupActivities_UIKit.PeoplePickerController: 0x600005020980> Failed to build remote hostViewController for <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250> Failed to fetch extensionViewController Calling -viewDidAppear: directly on a view controller is not supported, and may result in out-of-order callbacks and other inconsistent behavior. Use the -beginAppearanceTransition:animated: and -endAppearanceTransition APIs on UIViewController to manually drive appearance callbacks instead. Make a symbolic breakpoint at UIViewControllerAlertForAppearanceCallbackMisuse to catch this in the debugger. View controller: <_GroupActivities_UIKit.GroupActivitySharingController: 0x1417f1250> I got a similar error on iPadOS when the entitlement was not added. Now that I have the entitlement, the error appears only on MacOS. Does MacOS/MacCatalyst use a different entitlements file? What could be cuasing this?

Preparing an iPad App for native MacOS experience using Mac Catalyst (and AppKit when needed) and using SwiftUI. We observe that Horizontal Scroll is tricky using a Mouse! Most users have the habit of click+drag to scroll horizontally. This does not seem to be default behavior on ScrollView. Strange: Same App when compiled on "Mac (Designed for iPad)" [aka Silicon only] scrolls horizontally with click drag. But not if compiled with Mac Catalyst. Question: How can we enable general click-drag for horizontal scrolling using SwiftUI on Mac Catalyst? I wouldn't mind using specific AppKit framework if needed. Thanks in advance.

Hi, I have an imagePickerController where .allowsEditing is set to true after picking an image. I can move/scale it in iPhone/iPad simulators, but running on my Mac the scaling part of it doesn't work and I don't know how I could go about making the scaling work. Any suggestions much appreciated. Update: I am using a Magic Mouse. No Trackpad or Touchscreeen Mac.

I experience an issue with SceneKit that is driving me crazy ;( I have severe hangs when I disable Metal API Validation (which is default when you don't run from Xcode). So is there any way to force enable Metal API Validation for AppStore binary? (run MTL_DEBUG_LAYER=1 for Testflight or App Store) Hangs happen on Catalyst but also on iOS if I use lightingEnvironment...

We have an iOS app with a web View. To develop and debug, we inspect the web view using Safari Dev Tools (Developer menu). This Works: We are able to inspect the web view when the application is run on physical devices as well as on simulated devices (iPhone and iPad). This Does NOT Work: We are not able to inspect the web view of the same app running, unmodified, on same Mac. Safari’s Developer menu says “No Inspectable Applications” against the Mac. Requesting guidance or leads on ways to inspect and debug the app under these conditions. Many thanks!

In our mac catalyst app we access AppKit api's by using MacOS bundle(plugin). when using CGDisplayCreateImage(_: CGDirectDisplayID, rect: CGRect) method the plugin crashes.

Running in a Mac (Catalyst) target or Apple Silicon (designed for iPad). Just accessing the playbackStoreID from the MPMediaItem shows this error in the console: -[ITMediaItem valueForMPMediaEntityProperty:]: Unhandled MPMediaEntityProperty subscriptionStoreItemAdamID. The value returned is always “”. This works as expected on iOS and iPadOS, returning a valid playbackStoreID. import SwiftUI import MediaPlayer @main struct PSIDDemoApp: App { var body: some Scene { WindowGroup { Text("playbackStoreID demo") .task { let authResult = await MPMediaLibrary.requestAuthorization() if authResult == .authorized { if let item = MPMediaQuery.songs().items?.first { let persistentID = item.persistentID let playbackStoreID = item.playbackStoreID // <--- Here print("Item \(persistentID), \(playbackStoreID)") } } } } } } Xcode 15.1, also tested with Xcode 15.3 beta 2. MacOS Sonoma 14.3.1 FB13607631

It appears the app is sandboxed. I need to be able to access the broader file-system and pick a folder/file. Is this possible? Is it possible to invoke the app with a command-line argument? If so, how is it accessed (in code)?

While I'm keen on being on the latest version of macOS, I'm having trouble meeting the requirement that my app can run on a version of macOS that doesn't exist :) I'm using Xcode 15.2 (15C500b), targeting iOS 17.2. I've elected to have the App Store choose the minimum version for Catalyst. I've also tried selecting a version. ITMS-90899: Apple silicon Mac support issue - The app is not compatible with the provided minimum macOS version of 14.2. It can run on macOS 14.4 or later. Please specify an LSMinimumSystemVersion value of 14.4 or later in a new build, or select a compatible version in App Store Connect. For details, visit: ... Is there something I could be doing wrong to prompt this behaviour?

Running a Process executableURL path for a Catalyst target using a macOS type bundle returns the following error as output: (/Applications/Xcode-15.1.0.app/Contents/Developer/Platforms/MacOSX.platform/Developer/Library/Debugger/libViewDebuggerSupport_macCatalyst.dylib), but incompatible platform (have \'MacCatalyst\', need \'macOS\')) Is it possible to set which dylib platform is used by the macOS bundle executable file instead of using the MacCatalyst one?

Hello, I am working on an AUv3 extension project using SwiftUI in Xcode and have encountered a peculiar issue when implementing a simple alert on Mac Catalyst. The code is straightforward; it's merely an alert triggered by a button within a SwiftUI view. Here's the relevant portion of the code: import SwiftUI struct SwiftAUv3ExtensionMainView: View { var parameterTree: ObservableAUParameterGroup @State var showingAlert = false var body: some View { VStack { ParameterSlider(param: parameterTree.global.gain) Button(action: {showingAlert = true}, label: { Text("Button") }) } .alert("Alert", isPresented: $showingAlert, actions: {}, message: { Text("Message") }) } } The problem arises when this alert is displayed and subsequently closed. Upon closing the alert, the cursor turns into a spinning rainbow and the app freezes for several seconds. Additionally, Xcode's console displays the warning: -[NSWindow makeKeyWindow] called on _NSAlertPanel which returned NO from -[NSWindow canBecomeKeyWindow]. I am looking for insights or solutions to address this issue. Has anyone else experienced similar problems with SwiftUI alerts in AUv3 extension projects, especially when using Mac Catalyst? Any advice or suggestions would be greatly appreciated. Thank you.
