So experimenting with UISplitViewController on Mac Catalyst. I have a triple split. The primary view controller is a sidebar. I have the default sidebar button showing in the toolbar and that collapsed/expands the sidebar fine. But when I drag to try to collapse the split (as is typical on macOS) the sidebar doesn't collapse. It clamps to the min. size. Is there anyway to enable this? I tried passing 0 to -setMinimumPrimaryColumnWidth: but that didn't work.

So I'm looking inside the documentation for TipKit, which ~1400 lines in a single file of documentation. If I right click a symbol there is no "Jump to Definition" in the context menu. Steps to reproduce: Navigate to TipKit generated "header". Right click a symbol like Tip (highlighted in bold): public struct AnyTip : Tip 3rd step) No Jump to Definition menu item appears in the context menu. Is this intentional behavior?

I have a customizable NSToolbar (using in a Mac Catalyst app "optimized for Mac"). When I right click and choose "Customize toolbar" I get the following error: Conflicting constraints detected: ( "<NSLayoutConstraint:0x6000014a24e0 NSToolbarItemGroupView:0x13de568c0.width <= 88.5 (active)>", "<NSAutoresizingMaskLayoutConstraint:0x6000014f5f90 h=--& v=--& NSToolbarItemGroupView:0x13de568c0.width == 89 (active)>" ).

Unable to simultaneously satisfy constraints: ( "<NSLayoutConstraint:0x6000014a24e0 NSToolbarItemGroupView:0x13de568c0.width <= 88.5 (active)>", "<NSAutoresizingMaskLayoutConstraint:0x6000014f5f90 h=--& v=--& NSToolbarItemGroupView:0x13de568c0.width == 89 (active)>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x6000014a24e0 NSToolbarItemGroupView:0x13de568c0.width <= 88.5 (active)> Set the NSUserDefault >NSConstraintBasedLayoutVisualizeMutuallyExclusiveConstraints to YES to have ->[NSWindow visualizeConstraints:] automatically called when this happens. And/or, set a symbolic breakpoint on LAYOUT_CONSTRAINTS_NOT_SATISFIABLE to catch this in the debugger.

In Xcode 15 Live Previews are available for UIKit view controllers and views. However I noticed they do not work if the deployment target is < 17.0. If I try to make a live preview for a view controller like so: #Preview { let someVC = ViewController() return someVC } It doesn't load. The error is described below: == PREVIEW UPDATE ERROR: CompileDylibError: Failed to build ASwiftViewController.swift Compiling failed: module 'SwiftUI' has no member named 'VStack' If I raise the deployment target to iOS 17 it starts working.

I'm trying to enable the web inspector on WKWebView in a Mac Catalyst app. I'm only doing this for debugging purposes. In the released the web inspector will not be enabled. Doing this under Mac Catalyst does not work:  WKPreferences *prefs = [[WKPreferences alloc]init];   [prefs _setDeveloperExtrasEnabled:YES]; //Assign the WKPreferences to a WKWebViewConfiguration and create the web view.. Is there any way to do this? Thanks in advance.

I see the -resumeAllMediaPlayback: says the replacement method is -setAllMediaPlaybackSuspended:completionHandler: I don't believe suspending and resuming media playback are matching actions, which would mean -resumeAllMediaPlayback: doesn't have a replacement API? The deprecated -resumeAllMediaPlayback: method doesn't seem to work on Sonoma (pauseAllMediaPlaybackWithCompletionHandler: does work but resume does not).

Is there a way to programmatically launch a macOS Action Extension (related documentation: https://developer.apple.com/library/archive/documentation/General/Conceptual/ExtensibilityPG/Action.html) I'm aware how to create "Action Extensions" but they only seem to be activated from NSTextView "rollover" button. Say I know there is an action extension that works on a particular type of data can I launch it from my app? Obviously we can launch "regular" apps with NSWorkspace by bundle iD but I was wondering if there is any API where my app could directly launch an action extension as the "host app" programmatically.

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 have a global variable in WKUserScript declared as a const in Javascript. I load this script in a custom WKContentWorld I create with my own name (not the pageWorld or default world). There some nasty javascript out there on most popular sites. I noticed that unhandled errors on the page can break stop my WKUserScript from working. In one particular case there is this nasty script on page for ads that uses document.write like so: b.contentWindow.document.write(e), b.contentWindow.document.close() And the web inspector shows an error here "Can't create duplicate variable: 'MyGlobalVariableNameInsMyUserScriptHere'" This script being used on the web page is going to end up getting blocked. But my question is this, isn't using my own content world supposed to protect me against this type of thing? This global javascript variable (an array) is global in my javascript file and holds some data in it but it is not inserted into the DOM. Shouldn't document.write/document.close calls from the page not cause this type of error in my user script? And if the entire DOM is being rewritten shouldn't a new script (representing my user script) be created from scratch? I think I can avoid the error by changing the variable from const to var (haven't tried yet). But is this how it's supposed to be?

I have a WKWebView that sets the UIDelegate: self.webView.UIDelegate = self; The following methods are never called when I right click in the WKWebView to being up a context menu: -(void)webView:(WKWebView*)webView contextMenuForElement:(WKContextMenuElementInfo*)elementInfo willCommitWithAnimator:(id <UIContextMenuInteractionCommitAnimating>)animator -(void)webView:(WKWebView*)webView contextMenuConfigurationForElement:(WKContextMenuElementInfo*)elementInfo completionHandler:(void (^)(UIContextMenuConfiguration * _Nullable configuration))completionHandler - (void)webView:(WKWebView *)webView contextMenuDidEndForElement:(WKContextMenuElementInfo *)elementInfo; This is from a Mac Catalyst app (I'm on macOS 14.0 23A344)

So I have a WKWebView with a loaded page. This page is playing an embedded Youtube video. The playback state is WKMediaPlaybackStatePlaying. All good. Then I click a link on the page (navigation jumps to a new page) and the video is no longer playing. No video or audio. The navigationDelegate calls -webView:didFinishNavigation: And my navigationDelegate call -requestMediaPlaybackStateWithCompletionHandler: on the webview from within -webView:didFinishNavigation: And in the completion handler of -requestMediaPlaybackStateWithCompletionHandler: the playback state is WKMediaPlaybackStatePlaying but nothing is playing because we are on a new page.... I even tried calling -requestMediaPlaybackStateWithCompletionHandler: after a delay but that doesn't seem to make a difference (even gave it a delay as long as 5 seconds)

I'm aware signing in to an Apple ID on a macOS Virtual Machine is not supported, unfortunately. But is there a way to download Xcode from within the VM? I know the developer website used to have links where you could directly download Xcode outside the Mac App Store but I can't seem to find it?

Have an app I'm working on that stores an item in the keychain. Everything was was working fine. I have a button in the UI that allows the user to clear out the keychain item:NSDictionary *query = @{(__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: service, (__bridge id)kSecAttrAccount: accountKey}; OSStatus status = SecItemDelete((__bridge CFDictionaryRef)(query));Status is -25244 which is errSecInvalidOwnerEdit. This app created the keychain item to begin with. What would be the appropriate way to handle this type of error?

I'm trying to convert a PyTorch forward Transformer model to CoreML but am running into several issues, like these errors: "For mlprogram, inputs with infinite upper_bound is not allowed. Please set upper. bound" 570 • to a positive value in "RangeDim)" for the "inputs" param in ct.convert().' raise NotImplementedError ( 259 "inplace_ops pass doesn't yet support append op inside conditional" Are there any more samples besides https://developer.apple.com/videos/play/tech-talks/10154 The sample in that video an imageType is used as input but in my model text is the input (and the output). I also get warned that converting "torch script" is experimental but in the video it says it a torch script is required to convert (though I know the video is a few years old).

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.
