Hello, given this following simple SwiftUI setup: struct ContentView: View { var body: some View { CustomFocusView() } } struct CustomFocusView: View { @FocusState private var isFocused: Bool var body: some View { color .frame(width: 128, height: 128) .focusable(true) .focused($isFocused) .onTapGesture { isFocused.toggle() } .onKeyPress("a") { print("A pressed") return .handled } } var color: Color { isFocused ? .blue : .red } } If I run this via Mac – Designed for iPad, the CustomFocusView toggles focus as expected and cycles through red and blue. Now if I run this same exact code via Mac Catalyst absolutely nothing happens and so far I wasn't able to ever get this view to accept focused state. Is this expected? I would appreciate if anyone could hint me on how to get this working. Thank and best regards!

I have an iOS app which has an embedded Quicklook Extension that works perfectly - in the Files app on iPad/iPhone I can QuickLook view and edit custom file types without problems. However, when I run the app on a Silicon Mac using Mac Catalyst (or (Made For iPad)) while the Finder does recognise the custom file types (allowing "Open in…" or double-clicking to open) it does not show the Quick Look extension. How do I add Finder QuickLook extension functionality to a Mac Catalyst app? Thanks

Hello, I have encountered a question that I hope to receive an answer to. Currently, I am working on a music project for Mac Catalyst and need to enable music files such as FLAC to be opened by right clicking to view my Mac Catalyst app. But currently, I have encountered a problem where I can see my app option in the right-click open mode after debugging the newly created macOS project using the following configuration. But when I created an iOS project and converted it to a Mac Catalyst app, and then modified the info.plist with the same configuration, I couldn't see my app in the open mode after debugging. May I ask how to solve this problem? Do I need to configure any permissions or features in the Mac Catalyst project? I have been searching for a long time but have not found a solution regarding it. Please resolve it, thank you. Here is the configuration of my macOS project: CFBundleDocumentTypes CFBundleTypeExtensions flac CFBundleTypeIconSystemGenerated 1 CFBundleTypeName FLAC Audio File CFBundleTypeRole Viewer LSHandlerRank Default Note: Sandbox permissions have been enabled for both the macOS project and the iOS to Mac Catalyst project. The Mac Catalyst project also has additional permissions for com. apple. security. files. user taught. read write

I was trying to set custom audio output device for a generated audio on macCatalyst. While using let status = AudioUnitSetProperty(outputUnit, kAudioOutputUnitProperty_CurrentDevice, kAudioUnitScope_Global, 0, &outputDeviceID, UInt32(MemoryLayout.size)) kAudioOutputUnitProperty_CurrentDevice is invalid, and status = -10879, indicating an error. STEPS TO REPRODUCE Set Run Destination to MacOS and run the program. "AudioUnitSetProperty: 0" should be printed, indicating it works fine. Set Run Destination to Mac Catalyst and run the program. "Error setting output device: -10879" should be printed, indicating an error.

I'm trying to use ScreenCaptureKit on a Mac Catalyst app, on macOS 12.5.1. I'm not sure if I'm doing something wrong, but it crashes as soon as I try to request SCShareableContent. It crashes on internal code, calling a method it can't find, which makes me think this is a bug in the framework rather than incorrect configuration. Any hints on how to work around this problem? The crash is: ** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[RPDaemonProxy fetchShareableContentWithOption:windowID:withCompletionHandler:]: unrecognized selector sent to instance 0x6000037d5dc0' terminating with uncaught exception of type NSException ScreenCaptureKit-Crash.txt

Okay so I'm getting this log every time I present a UIAlertController: Mac Catalyst: Presenting view controller <UIAlertController: 0x10f027000> from detached view controller <MyViewController: 0x10d104080> is not supported, and may result in incorrect safe area insets and a corrupt root presentation. Make sure <MyViewController: 0x10d104080> is in the view controller hierarchy before presenting from it. Will become a hard exception in a future release. A few points: MyViewController is not detached and the presentation shows just fine. I specifically check for this before presenting the alert controller like so: BOOL okayToPresentError = (self.isViewLoaded && self.view.window != nil); if (okayToPresentError) { [self presentErrorInAlertController:error]; } else { //Wait until view did appear. self.errorToPresentInViewDidAppear = error; } It spews out every time an error is fed back to my app and I present the alert controller (I can turn off the network connection and I show an alert controller with a "retry" button in it which will loop the error back so I can replay the error alert presentation over and over again) . Every time the alert controller is presented, I get this spewing in the console. Please don't start throwing hard exceptions because the check is faulty.

Prior to Sequoia, Mac Catalyst Apps worked fine when using group folders that started with group. They now get an alert that the Mac Catalyst app is trying to access data from other applications. This may also impact some SwiftUI developers. According to this the documentation for the App Group Entitlements entitlement, on macOS we should begin use the Team Identifier instead of group. Should Mac Catalyst follow the macOS or iOS rules for com.apple.security.application-groups? If they should need to follow the macOS rules now, that creates several issues for developers. We would now need separate build targets to pick up the different Entitlements files. More distressing is that we would need to do some kind of migration process to get our files to the new location. There wouldn't be a transparent way to do so where the user wasn't warned about the application accessing files that don't belong to it. Any clarification on what Mac Catalyst developers should be doing to prepare for Sequoia would be greatly appreciated.

Currently I came across an issue in mac catalyst project. All the buttons in my project are not visible, they are in their actual positions and also clickable and performing their tasks as assigned but they are not visible. When Iam doing: crossButton.setImage(UIImage(named: "CrossComMac"), for: .normal) Button does not contain image While in the below code, image is visible but Iam not able to resize it. crossButton.imageView?.image = UIImage(named: "CrossComMac") Also title of the button is not visible too. Anything related to button in my mac catalyst project is not visible. Main issue: Button's image is visible in Xcode running project Button's image is not visible in build project...(funny thing right)

Hello! I discovered a bug on Catalyst about a three years ago but it still seems to be not fixed. My bug report number is FB9705748. The Internet is silent on this so I'm even not sure, perhaps it's only me. So to the problem. When you display UICollectionViewController or UIViewController that contains UICollectionView, interact with the collection view then dismiss the view controller, the displayed view controller isn't released if dismissal is done through navigation bar item. The problem occurs only when the run target is My Mac (Mac Catalyst). Everything is fine when you run on iOS or via My Mac (Designed for iPad). The sample project is uploaded to GitHub. It has a video that shows this strange behavior, see the log for 'deinit' messages. I did have some workaround to fix this but it stops to work, presumable on the new macOS. Also, chances are that it's not only UICollectionView which initiates the glitch, it's just that I only encounter it with collection views.

I have created a Mac Catalyst version of the same app, and it was transferred from an old account to a new one. However, the Mac Catalyst build has been stuck in progress for several days when attempting to notarize it. After many days, I got the rejection with the following error: Team is not yet configured for notarization. Please contact Developer Programs Support at developer.apple.com under the topic Development and Technical / Other Development or Technical Questions. I have already tried to create a new developer ID certificate, but it still has the same issue. On the other hand, the iOS app is working fine and has been published in the App Store. Could you please assist us in resolving this issue as quickly as possible? Your prompt help would be greatly appreciated.

We have a IOS app and we are using the same app for Mac Catalyst. In IOS we are able to detect when user take the screenshot using UIApplicationUserDidTakeScreenshotNotification. But in MACCatalyst it is not working. As per docs UIApplicationUserDidTakeScreenshotNotification and UIScreenCapturedDidChangeNotification are both supported for MacCatalyst 13.1+. But I am not getting screen shot notifications using both

I have an iOS app which I'm trying to ship to the Mac App Store. The app was created for iOS 7, but has been kept up to date. I mention it because it has an old project file. I'm able to build and run the app on my Silicon Mac fine. However, when I archive with target "My Mac (Designed for iPad)", I get an archive of type "iOS App Archive". Here's what I've checked: Target is set to “My Mac (Designed for iPad)” “SUPPORTS_MACCATALYST” is set to “YES” on the main target and the extensions “MACOSX_DEPLOYMENT_TARGET” set to “14.6” on the main target and the extensions “Supported Platforms” is set to “iOS” except for Watch targets and targets which also run on watchOS. If I filter the build logs for "Catalyst" there are no results. If I filter them for "Mac" there are no relevant results. Clean build folder Delete derived data Restart Xcode Xcode Version 16.2 (16C5032a) macOS Version 15.2 Other notes: The app has a widget extension and an intents extension and two custom frameworks When I try and archive for Mac using Xcode Cloud, it runs for 90 minutes and then fails. I suspect it’s related to this issue but I’m not sure. I’ve had issues like this solved with DTS before, but that isn’t allowed any more. Any help would be greatly appreciated.

We are developing an MacOS app from our iOS app using MacCatalyst. If I press long on the app icon on the Dock, a list of recent files appears. If I tap one one of these files nothing happens. I would expect the scene delegate function: func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) would be called but it is not. Can somebody maybe explain what I am missing here? The list of recent files also appears in the Menu under File > Open recent files. There I can tap on a file and it it is opened correctly using the scene delegate method mentioned above. The files can also be opened with the app using the Finder, so the associated file types with the app are correct.

I'm trying to build a Multiplatform app for Mac but get this incomprehensible error. Anyone any idea what this means and how to fix it? "Driver threw Swift requires a minimum deployment target of iOS 7.0.0 without emitting errors."

I don't know why, but for my MacCatalyst target, I have to make my view controller Y orgin 36 and the subtract the view height by 36 points, or the view is clipped. The following works in my main UIViewController, but feels super hacky. I'd feel better if I understood the issue and addressed it properly. override func viewWillLayoutSubviews() { super.viewWillLayoutSubviews() #if targetEnvironment(macCatalyst) if view.frame.origin.y < 1 { let f = UIApplication.shared.sceneBounds let newFrame = CGRect(x: 0.0, y: 36, width: f.size.width, height: f.size.height - 36) self.view.frame = newFrame } #endif } My guess is it starts the view under the title bar, but I have these set in the view controller: self.extendedLayoutIncludesOpaqueBars = false self.edgesForExtendedLayout = []

I have a text based action for iPhone and Mac Catalyst I am developing in Xcode 14.3.1 on macOS 13.4.1. I have the container app, an action and an AppGroup defined. I have confirmed that I can read the necessary shared defaults when the action launches. At this point the UI for the action is a simple textview in which I hope to display a modified version of the text passed to the action in the NSExtensionItems. I am not using a simulator. I am running the action directly using Xcode. What is happening is that the ActionViewController viewDidLoad runs but no visible window opens. In the console I see this as the action launches: 2023-07-05 18:27:23.692277-0700 XYZ[4634:279295] [ViewBridge] ViewBridge attempted to look up a hosted window with identifier 8E816BD5-67D3-402D-ADEB-AC59EDFA1F3B, but it was never registered. 2023-07-05 18:27:23.692408-0700 XYZ[4634:279295] [WindowHosting] UIScene property of UINSSceneViewController was accessed before it was set. .... The last line above is repeated 12 times.... Any helpful ideas would be deeply appreciated! Steve

Getting this error several times when presenting a modal window over my splitview window when running it on my Mac using Swift/Mac Catalyst in XCode 14.2.

(The "bleep" was a debugging print code I put in the unwind segue). I'm working through Apple's Mac Catalyst tutorial but it seems to be riddled with bugs and coding issues, even in the final part of the completed app which I dowmloaded and ran. I don't see these problems on IPad simulator. I don't know if it's because Catalyst has problems itself or there's something else going on that I can fix myself. Any insight into these errors would be very much appreciated! PS: The app seems to run ok on Mac without crashing despite the muliple issues

When running a Mac Catalyst app that uses DocumentGroup, the app fails to display the document content. The document picker works as expected, but creating a new document or opening an existing one results in an empty window. This issue occurs regardless of whether “Optimize for Mac” or “Scale iPad” is selected. Steps to Reproduce: 1. Download the sample project provided by Apple for building a document-based app in SwiftUI. 2. Delete the macOS version of the project. 3. Add a Mac Catalyst version of the app. 4. In the Mac Catalyst settings, select “Optimize for Mac” (the bug also appears if it is “Scale iPad”). 5. Run the project on macOS. Expected Result: The app should correctly display the content of the document when creating or opening it. Actual Result: The app opens an empty window when a new document is created or an existing one is opened. Impact: We have received multiple 1-star reviews, and our retention has dropped by two-thirds due to this issue. Environment: Xcode 16.1; macOS 15.1 & 15.2 (on 15.0 it works fine) Has anyone experienced the same issue? I filed multiple reports so far.

I just want Mac Catalyst app can look up the SSID of the currently connected WiFI. Xcode returns I can't use CoreWLan in Mac Catalyst, so I used NEHotspotNetwork, although I do not have convince whether Mac Catalyst allows it. The same code of destination works fine on iPhone, but not on Mac Catalyst and Mac(Designed for iPad). What is the proper way to get SSID of WiFI in Mac Catalyst? Is there another way to do this? The code I tried is below and I used CoreLocation API before call this function. func getWiFiSsid() { NEHotspotNetwork.fetchCurrent { network in if let network = network { print(network) } else { print("network is nil!") } } } Below is Entitlement file.
