Setting elementFullscreenEnabled property to YES on WKPreferences is not honored on Mac Catalyst.  WKWebViewConfiguration *webViewConfig = [[WKWebViewConfiguration alloc]init];  WKPreferences *prefs = [[WKPreferences alloc]init]; prefs.elementFullscreenEnabled = YES;   webViewConfig.preferences = prefs; //then create the WKWebView.. I load a Youtube url in the WKWebView. Youtube complains that the browser doesn't support full screen. Is there a workaround? Full screen does work in an AppKit app though using the exact same API...though it causes an Autolayout crash (I will be making another thread about that separate issue shortly).

I'm trying to create a dynamic menu on Mac Catalyst. Using a UIBarButtonitem like so to make a "pull down" button: UIDeferredMenuElement *deferredmenuElement; deferredmenuElement = [UIDeferredMenuElement elementWithUncachedProvider:^(void (^ _Nonnull completion)(NSArray<UIMenuElement *> * _Nonnull)) { UIAction *actionOne = [UIAction actionWithTitle:@"Action One" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action one fired."); }]; UIAction *actionTwo = [UIAction actionWithTitle:@"Action Two" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action two fired."); }]; UIAction *actionThree = [UIAction actionWithTitle:@"Action Three" image:nil identifier:nil handler:^(__kindof UIAction * _Nonnull action) { NSLog(@"action three fired."); }]; completion(@[actionOne,actionTwo,actionThree]); }]; UIMenu *wrappedMenu = [UIMenu menuWithChildren:@[deferredmenuElement]]; UIBarButtonItem *uiBarButtonItem = [[UIBarButtonItem alloc]initWithTitle:nil menu:wrappedMenu]; uiBarButtonItem.image = [UIImage systemImageNamed:@"rectangle.and.pencil.and.ellipsis"]; self.navigationItem.rightBarButtonItems = @[uiBarButtonItem]; The button appears in the toolbar but when I click it to expose the menu I get a menu with on element in it that says "Loading...". The the uncached provider block is never called. Running Ventura 13.2.1 and Xcode 14.2.

I have looked high and low all and cannot find an answer or solution. I have an app that is primarily used by Mac users. I am looking to implement promo codes in the coming weeks. The presentCodeRedemptionSheet call does not work for Mac Catalyst apps saying "This function doesn’t affect Mac apps built with Mac Catalyst" in the documentation. AppStore.presentOfferCodeRedeemSheet also does not work for Mac Catalyst. If it is the case that you can't redeem in-app, that is fine if I can direct users to the Mac App Store to redeem promo codes, but I cannot find a way to do that either. I can only find a route to redeem gift cards. I have also tried clicking on a specific promo code link (something like https://apps.apple.com/redeem?ctx=offercodes&id=00000000&code=PROMOCODE) and that just redirects to the Gift Card redemption screen in the Mac App Store. So is there any way for a Mac only user (a user that does not have an iPhone or iPad) to use app promo codes? Thanks!

Hi, I am giving Mac Catalyst a try and Apple has provided a tutorial for that but it seems a bit buggy. In the tutorial https://developer.apple.com/tutorials/mac-catalyst/updating-the-app-icon there is the completed Catalyst xcode project (in the Complete folder). I downloaded and ran the completed project in Xcode Version 14.2, using my Mac to run it in simulation. The toolbar at the top of the window has the icons for edit and favorite but they appear to be greyed out and don't do anything when clicked. The selectors are set properly for their actions in the ToolBarDelegate file but nothing happens when I select a recipe, which it appears you have to do in order for those buttons to work, then try to click either one of those items Those buttons never appear to be enabled at all even though I have selected a recipe and the coding seems correct. I am confused as to why this doesn't work. The NSSharingServicePickerToolbarItem is enabled and seems to work. I didn't post any code since the project can be readily downloaded and viewed/run. Any help is much appreciated

0 I am developing a Mac Catalyst app using UIKit. I have set the "Mac Catalyst Interface" of the target to "Optimize for Mac". All UISliders in my app update their UI "one interaction late": When I click on the slider track, the value of the slider changes accordingly, but the knob does not move to the appropriate position. Only when I click the second time, the knob moves to that position. But when I click on a different position on the track instead, the knob will move to the location corresponding to the previous click. What I tried: Changing "isContinuous", it has no effect. Listen for the "valueChanged" event and in the handler call "setNeedsLayout()" on the slider. Listen for the "valueChanged" event and in the handler call "setNeedsDisplay()" on the slider. When I change the target's "Mac Catalyst Interface" to "Scaled to match iPad", UISlider behaves as expected. But I need it to be "Optimize for Mac". FWIW, here is my code to add a UISlider in a UIViewController, it is super basic stuff: import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() let slider = UISlider() view.addSubview(slider) slider.translatesAutoresizingMaskIntoConstraints = false NSLayoutConstraint.activate([ slider.heightAnchor.constraint(equalToConstant: 50), slider.widthAnchor.constraint(equalToConstant: 300), slider.centerXAnchor.constraint(equalTo: view.centerXAnchor), slider.centerYAnchor.constraint(equalTo: view.centerYAnchor) ]) slider.addTarget(self, action: #selector(onSlider(_:)), for: .valueChanged) } @objc func onSlider(_ slider: UISlider) { // slider.setNeedsLayout() // slider.setNeedsDisplay() print("on slider: \(slider.value)") } }

I have a multiple window Mac Catalyst app. I'm using a NSToolbar and the menu bar via UIMenuBuilder. I noticed after changing windows the menu bar isn't always validating properly. For example my app implements "Undo" and "redo". So I can reproduce the issue using these steps: Perform an action that can be undone. Open a new window. This new window has its own undo manager. In the Menu bar select Edit -> Undo Undo validates even though the current window has nothing on its local undo stack. If invoked undo is performed on the inactive window which definitely seems wrong. The same thing sometimes happens in reverse (that is, undo doesn't validate when it should after switching windows). This also happens with other actions after switching windows. Sometimes I can get the actions to validate by hitting the Tab key to move focus then shift tabbing back, which seems to force proper lookup in the responder chain (but sometimes that doesn't work). It seems that Catalyst is losing track of the real active window/window scene for some reason and is validating actions on the wrong window scene. Anyone experience this and know where I could be going wrong and/or know of a possible workaround? I tried subclassing UIApplication and implementing the methods there (and then forwarding them to the active UIWindowScene). However this doesn't work, the wrong window scene has its activationState set to UISceneActivationStateForegroundActive when the problem occurs.

Hi, I'm building an app for iPhone, iPad and Mac (Mac Catalyst). Unfortunately when I'm adding Family Controls capability to project I'm unable to run Mac Catalyst version of app. Everything is compiling, it fails when run and shows "Could not launch App" Launch Service error IDELaunchErrorDomain: code 20 RBSRequestErrorDomain: code 5 NSPOSIXErrorDomain: code 153 iOS version work without any problems and Screen Time releated Api too. My minimum deployment target is iOS 15. Our permission for Family Controls to distribute in AppStore is currently processing but I guess it shouldn't has influence as I'm running debug. Best, Marcin

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

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

A good while back, I created a Mac Catalyst version of an app. The app uses UICalendarView for both iOS and Mac. I have multiple date selection enabled. In the past, I thought I could select multiple dates on the Mac without needing to use the Command key modifier. And now I can't. Is this a change or am I dreaming? How can I go back to being able to select multiple dates without using the command key modifier?

In Xcode 15 beta 6, building any Mac Catalyst project will encounter the following Linker warning. ld: warning: building for 'macCatalyst', but linking in dylib (/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa.tbd) built for 'macOS'

When initializing a CIColor with a dynamic UIColor (like the system colors that resolve differently based on light/dark mode) on macOS 14 (Mac Catalyst), the resulting CIColor is invalid/uninitialized. For instance: po CIColor(color: UIColor.systemGray2) → <uninitialized> po CIColor(color: UIColor.systemGray2.resolvedColor(with: .current)) → <CIColor 0x60000339afd0 (0.388235 0.388235 0.4 1) ExtendedSRGB> But also, not all colors work even when resolved: po CIColor(color: UIColor.systemGray.resolvedColor(with: .current)) → <uninitialized> I think this is caused by the color space of the resulting UIColor: po UIColor.systemGray.resolvedColor(with: .current) → kCGColorSpaceModelRGB 0.596078 0.596078 0.615686 1 po UIColor.systemGray2.resolvedColor(with: .current) → UIExtendedSRGBColorSpace 0.388235 0.388235 0.4 1 This worked correctly before in macOS 13.

I have an app which uses SwiftUI and Mac Catalyst. When running on a Mac I want to provide a preferences menu entry with the usual keyboard shortcut Command + ,. An implementation via the Settings bundle is out of question since my preferences are too complex for this. Here is a reduced example of my implementation: import SwiftUI @main struct PreferencesMenuTestApp: App { @UIApplicationDelegateAdaptor private var appDelegate: AppDelegate var body: some Scene { WindowGroup { ContentView() } } } class AppDelegate: UIResponder, UIApplicationDelegate { override func buildMenu(with builder: UIMenuBuilder) { let preferencesCommand = UIKeyCommand(title: "Preferences…", action: #selector(showPreferences), input: ",", modifierFlags: .command) // let preferencesCommand = UIAction(title: "Preferences…") { action in // debugPrint("show preferences") // } let menu = UIMenu(title: "Preferences…", options: .displayInline, children: [preferencesCommand]) builder.insertSibling(menu, afterMenu: .about) } @objc func showPreferences() { debugPrint("show preferences") } } The problem is that the menu entry is disabled. Obviously the provided selector is not recognised. When I mark the AppDelegate with @main, then the menu entry is enabled. Of course then the app's window is empty. When I switch to the UIAction implementation (the out commented code) it works fine. But since one cannot provide a keyboard shortcut for UIActions this is not a good solution. What am I missing? How would one implement a preferences menu entry that actually works?

I've got the following error on Mac Catalyst: TypeError: undefined is not an object (evaluating 'navigator.mediaDevices.getUserMedia') macOS 13.5.1 (22G 90) Safari 17.0 (18616.1.24.11.5, 18616) UserAgent "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/17.0 Safari/605.1.15" The same app works well on iOS.

Hello! New to swift development. I've created a very basic iOS app that uses the network extension to block web domains. Now, I am trying to make it work on a macOS using Mac Catalyst. However, when I build the project, I get this error: 2023-09-08 23:31:32.540010+0600 controlShift[69583:2468143] [Metadata] unable to get a dev_t for store 1795162192. 2023-09-08 23:31:33.986014+0600 controlShift[69583:2467453] [] -[NEFilterManager saveToPreferencesWithCompletionHandler:]_block_invoke_3: failed to save the new configuration: (null) The app launches and the UI works correctly. However, it fails to save the preference as stated in the error, so it does not block anything. Here is the relevant part of the code in the root file: var body: some Scene { WindowGroup { ContentView() .environment(\.managedObjectContext, persistenceController.container.viewContext) .onAppear { NEFilterManager.shared().loadFromPreferences { error in if let loadError = error { print("Failed to load the filter configuration: \(loadError)") return } } DispatchQueue.main.asyncAfter(deadline: .now()+1.5) { if NEFilterManager.shared().providerConfiguration == nil { let newConfiguration = NEFilterProviderConfiguration() newConfiguration.username = "UserName" newConfiguration.organization = "myApp " newConfiguration.filterBrowsers = true newConfiguration.filterSockets = true newConfiguration.serverAddress = "http://192.168.100.48:3000" NEFilterManager.shared().providerConfiguration = newConfiguration } NEFilterManager.shared().isEnabled = true NEFilterManager.shared().saveToPreferences { error in if let saveError = error { print("Failed to save the filter configuration: \(saveError)") } } } } } I'm at a loss for what is wrong. Lmk if you need additional details. Thanks! btw, I am very new to swift and iOS/macOS development in general so if there's a better way to write or structure the logic inside the "onAppear" method (of which I'm sure there is), lmk as well. ^_^

I'm trying to update our Mac version of our iOS app using Xcode 14.2, the update worked using Xcode 11. The detailed error is: Invalid Provisioning Profile. The provisioning profile included in the bundle maccatalyst.com.xxxxxxx.yyyyyyyy [maccatalyst.com.xxxxxxx.yyyyyyyy.pkg/Payload/yyyyyyy.app] is invalid.

When I build my app for my real device I get this error /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS16.4.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSURL.h:10:9 'Foundation/NSURLHandle.h' file not found I have latest macOS (13.5.2 (22G91)) and the latest Xcode (14.3.1 (14E300c)). I got this issue about 5 months now, even on my old Intel mac. My new M1 mac was not restored by a Backup and I still get this issue. Can someone please give me a hint or advice to get this issue fixed?

When using xcodebuild to build my project, I specify a destination of generic/platform=macOS Xcode informs me that my destination is ambiguous as there is a generic destination for Mac Catalyst. --- xcodebuild: WARNING: Using the first of multiple matching destinations: { platform:macOS, name:Any Mac } { platform:macOS, variant:Mac Catalyst, name:Any Mac } At the end of the day, that's OK. It's selected the proper destination by happenstance. But is there a way t change my destination specifier so that it can zero in on the MacOS destination that is not the MacCatalyst variant? I've tried using "generic/platform=macOS,variant=". But that does not work.
