I'm trying to implement a Help Window from Help Menu in macOS (Mac Catalyst). I have SceneConfiguration in Info.plist and multi-window enabled. Tapping Help menu opens a new Help Window on macOS. I thought it was working great! Unfortunately, tapping Help menu again opens a new Help Window. I only want one Help window to be shown. I expected UIApplication.shared.activateSceneSession(for: request) to use an existing UIScene if one was already present. In my experience I always get a new Scene and thus a new Window. What am I missing? AppDelegate.swift func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration { // It's important that each UISceneConfiguration have a unique configuration name. var configurationName: String! switch options.userActivities.first?.activityType { case UserActivity.HelpMenuActivityType: configurationName = SceneConfiguration.helpWindowConfiguration default: configurationName = SceneConfiguration.defaultConfiguration } return UISceneConfiguration(name: configurationName, sessionRole: connectingSceneSession.role) } override func buildMenu(with builder: UIMenuBuilder) { super.buildMenu(with: builder) ... builder.remove(menu: .help) builder.insertSibling(helpMenu(), afterMenu: .window) } func helpMenu() -> UIMenu { let children: [UIAction] = [ UIAction(... ) { [weak self] action in self?.helpMenuTappedHandler(action) } ] .... } func helpMenuTappedHandler(_ action: UIAction) { let userActivity: NSUserActivity = ... userActivity.targetContentIdentifier = ... let options: UIScene.ActivationRequestOptions = .init() options.requestingScene = ... let request: UISceneSessionActivationRequest = .init(role: .windowApplication, userActivity: userActivity, options: options) UIApplication.shared.activateSceneSession(for: request, errorHandler: handleHelpError) }

Hi, I have a IOS app and we are using fairplay DRM to play videos. In IOS app we are allowing offline download of the videos and hence we are getting a persistent fairplay license. In IOS app everything is working fine. Now we have used the same app and built for MacOS catalyst. In MAC OS catalyst app we are not able to play the video and getting error code -42650 We are able to get the persistent license from server, but when we play the video with the license we are getting the error. Below are the logs: 2024-12-06 22:05:48.911266+0530 0x4dffe2 Default 0x0 85505 0 teachonline: (MediaToolbox) [com.apple.coremedia:] <<<< FigPKDKeyManager >>>> keyManager_processOfflineKeyInternal: 0x600000322000 160D4519-C60B-4FD0-B69A-20B2A4597017 created decrypt context:0x0 with offline key; updated offline key:0x0 err:-42650 2024-12-06 22:05:48.911369+0530 0x4dffe2 Default 0x0 85505 0 teachonline: (MediaToolbox) [com.apple.coremedia:player] <<<< FigStreamPlayer >>>> fpfs_ensureDecryptorHasStarted: [0x7fc44e4dc520|P/NW] <0x7fc44fa44000|I/SRA.01>: track 1 latching decryptorFailure -42650 85505 0 teachonline: (MediaToolbox) [com.apple.coremedia:player] <<<< FigStreamPlayer >>>> fpfs_StopPlayingItem: [0x7fc44e4dc520|P/NW] <0x7fc44fa44000|I/SRA.01>: Pausing, err=Error Domain=CoreMediaErrorDomain Code=-42650 "(null)" I have copied only the lines which has errors.

A Mac Catalyst App Creates an AppKit Bundle Plugin in which @available does not work。 In AppKit Bundle Plugin, there is not watchOS and iOS version can not be higher than 28, but the log has been output. if (@available(watchOS 18.0, *)) { NSLog(@"bundle is available watchOS"); } if (@available(iOS 28.0, *)) { NSLog(@"bundle is available iOS"); } demo link: https://pan.baidu.com/s/1s_5qmsL6Bh-df3A1PfD0OA Extracted code: 5ndj

I'm trying to run an xctest bundle, built for catalyst, with xcrun. i.e. xcrun xctest path_to_my_test.xctest It fails, complaining that: The bundle "MyBundle" couldn't be loaded because it is damaged or missing necessary resources. Try reinstalling the bundle.....but incompatible platform (have 'MacCatalyst', need 'macOS') So it seems like because I'm not executing it in a sim it wants the bundle to be a macOS bundle. But I would have thought it would be possible to run a Mac Catalyst target directly on a macOS host the same as a native macOS test target. Is this not possible?

If I have a Catalyst app with a WKWebView and I select text, I can drag forward to extend the selection, but I can't reduce the length of the selected range by dragging backwards. I've reproduced this in a trivial sample app. Is there some property I need to set somewhere? I've filed this as FB15645411.

I'm experimenting with getting my AUv3 plugins working correctly on iOS and MacOS using Catalyst. I'm having trouble getting the plugin windows to look right in Logic Pro X on MacOS. My plugin is designed to look right in Garageband's minimal 'letterbox' layout (1024x335, or ~1:3 aspect ratio) I have implemented supportedViewConfigurations to help the host choose the best display dimensions On iOS this works, although Logic Pro iPad doesn't seem to call supportedViewConfigurations at all, only Garageband does. On MacOS, Logic Pro does call supportedViewConfigurations but only provides oversized screen sizes, making the plugins look awkward. I can also remove the supportedViewConfigurations method on MacOS, but this introduces other issues: I guess my question boils down to this: how do I tell Logic Pro X on MacOS what the optimal window size of my plugin is, using Mac Catalyst?

Hi, Firstly: The whole question is about MacCatalyst (in IOS it works as intended) In my Maccatalyst app I want to share Userdefaults between app and widget. I have added an app group to the widget and the app and have set up Userdefauls accordingly. Here is the problem: Xcode claims that the app group should start with "group.***" because Catalyst is based on iOS. If I do so, my Catalyst app rises the "App wants to access data from other apps" requester on EVERY launch. So, I can't use it in production. Even if I would accept the requester, the widget isn't able to access the defaults at all because it does not rise that requester, but silently ignores the access. In contrast, if I setup the app group name with our TeamID (instead of group.*) then the requester vanishes, but Xcode does not accept it, issuing a warning and displaying the app group in red. I don't think this is advisable 'state' for production code. Even then widget can't see the data either. What is the recommended way of sharing Userdefaults between Catalyst app and Catalyst Widget (not the iOS widget which displays the "open on iPhone warning" when clicked) on macOS ? Thanks

I am using a Mac Catalyst with SwiftUI for our document-based app with DocumentGroup. The issue is that when we create a new document or open an existing one, the opened view is completely blank. It is only blank/empty when the "Optimzie for Mac" is checked. If it is "Scaled t oMatch iPad", then it works well. Xcode 16.1 macOS 15.1 struct DocumentGroupTestApp: App { var body: some Scene { DocumentGroup(newDocument: WritingAppDocument()) { file in TestView() // it is empty when it gets opened. It does not work if the option "Optimize for Mac" is checked. If it is scale iPad, then it works. } } } struct TestView: View { var body: some View { Text("Hello, World!") } }

I couldn't find any documentation related to if WebRTC is supported in macOS/macOS Catalyst, but all my tests related to that fail. I also experience the same as in this post: https://developer.apple.com/forums/thread/695871?login=true Meanwhile in iOS it works well.

As of macOS Sequoia 15.1 (and probably earlier), in System Settings under Accessibility -> Display, there's a Text Size option that looks an awful lot like Dynamic Type on iOS: I have an iOS app with robust support for Dynamic Type that I've brought to the Mac via Catalyst. Is there any way for me to opt this app into supporting this setting, maybe with some Info.plist key? Calendar's Info.plist has a CTIgnoreUserFonts value set to true, but the Info.plist for Notes has no such value.

I have a Catalyst app that supports multiple scenes / windows. It has one "main" window type and lots of other secondary windows that can be opened. I'm using the system window restoration functionality via NSQuitAlwaysKeepsWindows to restore windows with their user activity data after the app is quit and restarted. Normally, this works great. If I open my app, change the size and position of my window, quit, and reopen it, the window size and position comes back as expected. But if I close the window using the red stoplight button and then click the app icon to bring it back, it comes back at the default position and size. This isn't how other system apps work - if I close the system Calendar app with the stoplight button, it comes back at the same size and position. How do I get this behavior with my Catalyst app? Is there some identifier property I need to set somewhere? I don't see such a property on UISceneConfiguration. If it matters, I'm using the configurationForConnectingSceneSession method to configure my windows when they open, instead of setting it up in the Info.plist.

I'm trying to debug a couple of crash reports for a Mac Catalyst app and seem to be unable to symbolicate my crash reports. In the Xcode Organizer, I see unsymbolicated lines for my app, despite having the original archive for the build in question. A search for the relevant dSYM (using the process from https://developer.apple.com/documentation/xcode/adding-identifiable-symbol-names-to-a-crash-report#Locate-a-dSYM-Using-Spotlight) yields no results. Unlike iOS builds, the "Download dSYMs" button isn't present in the organizer, nor is the option to download dSYMs from App Store Connect. I assume this is because macOS apps don't use bitcode. The app's Debug Information Format is set to DWARF with dSYM File. Has anyone else run into this issue? Any ideas about how I can symbolicate the crash logs?
