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. ....

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.

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.

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
