My configuration: A iOS app that supports Mac Catalyst. This Mac Catalyst app is “optimized for Mac” it is not scaled to match iPad. I open the asset catalog and add a “Data Asset” which is a .txt file. This is set to “Universal.” I add “Mac” variant for this data asset and I add a .txt with different text. I load the string at runtime like this: NSDataAsset *scriptData = [[NSDataAsset alloc]initWithName:@"TextDataAsset"]; NSString *loadedText = [[NSString alloc]initWithData:scriptData.data encoding:NSUTF8StringEncoding]; When I run that on Mac Catalyst the text loadedText is an empty string, which is wrong. Running on iOS I get the expected string. Is this the intended behavior? Am I supposed to use the "iPad" device for Mac assets (because I don't believe that is the case with images, etc.) In any case I filed FB12005255

I'm getting some new behavior I haven't seen before (on Venture 13.2.1) on UITableView. Steps to reproduce: A table view row is selected and I swipe to delete the selected row. After about a half of a second the table view selects another row. I'm not programmatically making a selection here after the swipe to delete. UIKit is doing it. I set a breakpoint in -tableView:didSelectRowAtIndexPath: and it is related to the focus system: #1 0x00000001b350b140 in -[UITableView _selectRowAtIndexPath:animated:scrollPosition:notifyDelegate:isCellMultiSelect:deselectPrevious:performCustomSelectionAction:] () #2 0x00000001b3512df8 in -[UITableView _didUpdateFocusInContext:withAnimationCoordinator:] () #3 0x0000000213b38988 in -[UITableViewAccessibility _didUpdateFocusInContext:withAnimationCoordinator:] () #4 0x00000001b2f54260 in __84-[UIFocusSystem _sendDidUpdateFocusNotificationsInContext:withAnimationCoordinator:]_block_invoke () #5 0x00000001b2f08944 in _UIFocusEnvironmentEnumerateAncestorEnvironments () #6 0x00000001b2f54480 in -[UIFocusSystem _sendNotificationsForFocusUpdateInContext:withAnimationCoordinator:usingBlock:] () #7 0x00000001b2f53ff0 in -[UIFocusSystem _sendDidUpdateFocusNotificationsInContext:withAnimationCoordinator:] () #8 0x00000001b2f53630 in -[UIFocusSystem _updateFocusWithContext:report:] () #9 0x00000001b2f5319c in -[UIFocusSystem updateFocusIfNeeded] () #10 0x00000001b2f561dc in __43-[UIFocusSystem _updateFocusUpdateThrottle]_block_invoke () #11 0x00000001b3725e70 in -[_UIAfterCACommitBlock run] () #12 0x00000001b37262cc in -[_UIAfterCACommitQueue flush] () #13 0x00000001b2851630 in _runAfterCACommitDeferredBlocks () #14 0x00000001b28513ac in _cleanUpAfterCAFlushAndRunDeferredBlocks () #15 0x00000001b28512c8 in _afterCACommitHandler () #16 0x00000001887b0db8 in CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION () #17 0x00000001887b0ca4 in __CFRunLoopDoObservers () This wasn't happening before. I'm not sure if it is related to the Ventura 13.2.1 update or if there is some minor tweak on my end that is causing this change in behavior though I'm not thrilling with UIKit making a selection without asking me about it. I could live with the automatic row selection if the next row below the deleted row was automatically selected but sometimes it is not. Sometimes UITableView is auto selecting a row two cells back which doesn't make any sense to me.

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 configured a WKWebView to support full screen elements like this:  WKWebViewConfiguration *webViewConfig = [[WKWebViewConfiguration alloc]init]; WKPreferences *prefs = [[WKPreferences alloc]init];  prefs.elementFullscreenEnabled = YES;  webViewConfig.preferences = prefs; //Create a WKWebView with the configuration and load a url like Youtube that supports playing videos in full screen.... Then I run the app and play a YouTube video. I enter full screen. Then I exit full screen and I hit an Autolayout crash. 0 libobjc.A.dylib 0x188365820 objc_msgSend + 32 1 CoreAutoLayout 0x1904ed82c -[NSLayoutConstraint _layoutEngine] + 36 2 CoreAutoLayout 0x1904ee3c0 __55+[NSLayoutConstraint _addOrRemoveConstraints:activate:]_block_invoke + 160 3 CoreAutoLayout 0x1904d4514 -[NSISEngine withBehaviors:performModifications:] + 88 4 CoreAutoLayout 0x1904ee238 +[NSLayoutConstraint _addOrRemoveConstraints:activate:] + 308 5 WebKit 0x1a82777fc -[WKFullScreenWindowController finishedExitFullScreenAnimationAndExitImmediately:] + 936 6 WebKit 0x1a7d63868 -[WKFullScreenWindowController windowDidExitFullScreen:] + 44 7 CoreFoundation 0x1887a6560 CFNOTIFICATIONCENTER_IS_CALLING_OUT_TO_AN_OBSERVER + 148 8 CoreFoundation 0x188844044 ___CFXRegistrationPost_block_invoke + 88 9 CoreFoundation 0x188843f8c _CFXRegistrationPost + 440 10 CoreFoundation 0x188777b64 _CFXNotificationPost + 708 11 Foundation 0x18966738c -[NSNotificationCenter postNotificationName:object:userInfo:] + 88 12 AppKit 0x18c4a3210 -[NSWindow(NSFullScreen) _didExitFullScreen] + 336 13 AppKit 0x18c2aa3ac -[_NSExitFullScreenTransitionController _doAfterExitFullScreen] + 304 14 AppKit 0x18c2acb28 ___NSRunLoopTimerCreateWithHandler_block_invoke + 56 15 CoreFoundation 0x1887cb54c CFRUNLOOP_IS_CALLING_OUT_TO_A_TIMER_CALLBACK_FUNCTION + 32 16 CoreFoundation 0x1887cb1f4 __CFRunLoopDoTimer + 940 17 CoreFoundation 0x1887cad4c __CFRunLoopDoTimers + 356 18 CoreFoundation 0x1887b0734 __CFRunLoopRun + 1896 19 CoreFoundation 0x1887af878 CFRunLoopRunSpecific + 612 20 HIToolbox 0x191e8ffa0 RunCurrentEventLoopInMode + 292 21 HIToolbox 0x191e8fde4 ReceiveNextEventCommon + 672 22 HIToolbox 0x191e8fb2c _BlockUntilNextEventMatchingListInModeWithFilter + 72 23 AppKit 0x18ba3584c _DPSNextEvent + 632 24 AppKit 0x18ba349dc -[NSApplication(NSEvent) _nextEventMatchingEventMask:untilDate:inMode:dequeue:] + 728 25 AppKit 0x18ba28e0c -[NSApplication run] + 464 26 AppKit 0x18ba00250 NSApplicationMain + 880 27 AppKitWKWebviewProjectForWebInspector 0x102fbbf80 main + 44 (main.m:14) 28 dyld 0x1883a7e50 start + 2544

When playing a video in WKWebView I get this exception thrown after playing a video in "Full window mode" (that is when video takes over the size of the window, not to be confused with "full screen mode").

Airplaying video doesn't seem to be working on Mac Catalyst (works on iOS). I'm on the same network. Testing on Youtube. The "Airplay" button appears but clicking it does nothing. Anyone else experiencing this?

I notice on some pages to be having text selection issues on Mac Catalyst. AppKit WKWebview appears to work better. Is there a workaround? Related: https://stackoverflow.com/questions/74959180/how-to-use-appkit-wkwebview-in-a-mac-catalyst-app https://stackoverflow.com/questions/61215569/macos-maccatalyst-wkwebview-text-selection-behavior Would be great if Mac Catalyst just got the normal Mac WKWebView but there appears to be differences.

I set the elementFullscreenEnabled property on WKPreferences to YES. On iPad this enables web videos to be played in full screen. However when I play the video and rotate the device, the layout becomes completely broken on orientation change. Anyone know of a workaround? I can key value observe the web view's full screen state property but there is no obvious way to get ahold of the UI being used to play the video?

So I copy a link to the pasteboard in Mac Catalyst. I can do this directly or by using system provided "Copy" in WKWebView from the WebUIDelegate method -webView:contextMenuForElement:willCommitWithAnimator: (which creates a "Copy Link action in the system provided "suggested actions"). So when I copy a link on Mac Catalyst like this: [UIPasteboard generalPasteboard].URLs = @[urlToCopy]; And I try to paste it in Xcode (assuming I'd be pasting the URL string in this context) Xcode plays NSBeep and nothing is pasted. I have to paste the link in TextEdit in a Plain Text Document, select the text, copy it again and then paste it back in Xcode. I'm having a pretty bad day here. Almost nothing is working.

I have a UISearchController. It uses a search results controller (the search results controller uses a UITableView). If I select a row.. scroll a bit, deactivate the window then reactivate the window the scroll position starts flying. Usually this random scroll exposes the selected row but sometimes it scroll elsewhere. I subclassed UITableView to try to figure out what's causing this random scrolling. I have a breakpoint in -scrollRectToVisible:scrollRectToVisible: -(void)scrollRectToVisible:(CGRect)rect animated:(BOOL)animated {     [super scrollRectToVisible:rect animated:animated]; //<--Break point here } And was able to determine that its coming from UIFocusSystem/UISearchController: #1 0x00000001d65d748c in -[UISearchController _willUpdateFocusInContext:withAnimationCoordinator:] () #2 0x00000001d611fdd0 in __85-[UIFocusSystem _sendWillUpdateFocusNotificationsInContext:withAnimationCoordinator:]_block_invoke () #3 0x00000001d60d4944 in _UIFocusEnvironmentEnumerateAncestorEnvironments () #4 0x00000001d6120480 in -[UIFocusSystem _sendNotificationsForFocusUpdateInContext:withAnimationCoordinator:usingBlock:] () #5 0x00000001d611faf8 in -[UIFocusSystem _sendWillUpdateFocusNotificationsInContext:withAnimationCoordinator:] () #6 0x00000001d611f42c in -[UIFocusSystem _updateFocusWithContext:report:] () #7 0x00000001d611b90c in -[UIFocusSystem _setEnabled:withAnimationCoordinator:] () #8 0x00000001d61a1128 in __49-[_UIFocusSystemSceneComponent _setupFocusSystem]_block_invoke () #9 0x00000001d618ccac in -[_UIFocusStateObserver notifyObserversIfNecessary] () -- Workarounds/input always appreciated.

When I use the verify receipt endpoint in my Mac apps, the Mac App Store review team always rejects them. I have apps that have been on the store for years that used this code and they verify in the production environment fine but every time I try to send an update it gets rejected. My app does simple receipt validation like this: My app uses the verify receipt endpoint and talks to the server directly (not super secure but that’s okay I don’t need to maintain a server for this app). The verify receipt endpoint always says the receipt is invalid in in the App Review team’s testing environment. My app calls exit(173) after the verify receipt endpoint tells me the receipt is invalid. The systems shows a dialog saying the app is Damaged. I cannot reproduce this in my testing environment nor do I see the issue occurring in the current versions of these apps live on the App Store (no code changes has been made to the receipt validation code). The issue seems to only occur in the App Review team’s testing environment. I've been running into this issue for about a year now. I had a TSI opened last year related to this but the issue never got resolved. I just have to comment out the receipt validation code in every app...then submit my update. Anyone else run into this with verify receipt?

I'm trying to configure the "Now Playing" information for my app on iOS. Using MPNowPlayingInfoCenter/MPRemoteCommandCenter is pretty straightforward for this. The issue I'm having is that the audio I'm playing is generated "on the fly" and I do not know the exact duration in seconds. I am able to synthesize an NSProgress to display the progress of the playback but the units are not in seconds. So if I use the NSProgress units with MPNowPlayingInfoCenter the "Now Playing" shows the units in seconds but it appears to be jumpy (because again my progress units are not in seconds but an approximation of the percent completed). [playInfo setObject:@(self.progress.totalUnitCount) forKey:MPMediaItemPropertyPlaybackDuration]; [playInfo setObject:@(self.progress.completedUnitCount) forKey:MPNowPlayingInfoPropertyElapsedPlaybackTime]; I see there is a MPNowPlayingInfoPropertyPlaybackProgress which looks like it would be perfect. I tried setting that instead of MPMediaItemPropertyPlaybackDuration/MPNowPlayingInfoPropertyElapsedPlaybackTime but it appears to have no effect in the "Now Playing" UI. I also tried setting MPNowPlayingInfoPropertyIsLiveStream to YES but that just makes the "Now Playing" UI display "Live" instead of the progress value. Is there a way I can show a progress bar without the units being displayed in seconds? Thanks in advance.

Edit: Was able to resolve. This thread may be deleted.

I’m using UISheetPresentationController with a UIViewController. While the sheet is being resized I’d like to position certain subviews a certain way during the resizing event. For example I may hide some subviews on a smaller detent and unhide them on a larger detent. But while the sheet is being resized in between the small and large detent I’d like to have some subviews placed at certain locations of the view hierarchy. As far as I can tell the only way to do this is with unreliable hard coded values: -(void)viewDidLayoutSubviews { [super viewDidLayoutSubviews]; CGFloat currentHeight = self.view.bounds.size.height; if (currentHeight <= mediumDetent) { [self doLayoutForMediumDetent]; } else if (currentHeight >= fullSizeDetent) { [self doLayoutForFullSizedDetent]; } else { [self doLayoutInBetweenFullAndMediumSheetWithCurrentSize:currentHeight]; } } I don't really know for sure the height of the detents. I'm using estimates so this layout code is fragile. For the medium detent the documentation states that it is "A system detent for a sheet that is approximately half the height of the screen, and is inactive in compact height." but on certain devices the medium detent height is not exactly 1/2 the screen height. Ideally it would be nice to have API like this: -(void)viewDidLayoutSubviews { [super viewDidLayoutSubviews]; CGFloat mediumHeight = [self.sheetPresentationController resolvedHeightForDetentWithIdentiier:someID withTraitCollection:self.traitCollection]; CGFloat fullHeight = [self.sheetPresentationController resolvedHeightForDetentWithIdentiier:FullSizeID withTraitCollection:self.traitCollection]; if (self.sheetPresentationController.isInLiveResize) { //do whatever during live resize } else { //do whatever at the current size } } Is there currently a better way to achieve what I'm after?

So I'm using a custom presentation controller which requires me to specify a transitioningDelegate on the view controller before presenting it like this: vcToPresent.modalPresentationStyle = UIModalPresentationCustom; vcToPresent.transitioningDelegate = transitionDelegate; Now I want to enforce a particular view controller to always use my custom presentation controller. Unfortunately I cannot just override the presentationController getter and return my own custom class; I have to make a transitioning delegate and an additional animator (and my custom presentation controller can animate alongside it). To have a view controller use my own presentation controller I have to do this: -(void)presentCustomVC { MyViewController *vcToPresent = [MyViewController makeViewController]; MyTransitioningDelegate *transitionDelegate = [[MyTransitioningDelegate alloc]init]; vcToPresent.modalPresentationStyle = UIModalPresentationCustom; vcToPresent.transitioningDelegate = transitionDelegate; [self presentViewController:vcToPresent animated:YES completion:nil]; } So I have to copy this transitioningDelegate set up code in every view controller that presents MyViewController. I can make the API look a little better by creating a factory method in MyViewController like this: +(MyViewController*)makeViewController { UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil]; MyViewController *theVC = [storyboard instantiateInitialViewController]; MyTransitioningDelegate *transDelegate = [[MyTransitioningDelegate alloc]init]; theVC.modalPresentationStyle = UIModalPresentationCustom; theVC.transitioningDelegate = transDelegate; return theVC; } The problem with that is the transitioningDelegate gets deallocated right away (before the view controller can be presented). The transitioningDelegate property on UIViewController is weak for some reason. Shouldn't the transitioningDelegate property be declared strong? My custom transitioningDelegate has no strong reference to the presented view controller? If I add a redundant property to MyViewController like this: @property (nonatomic,strong) MyTransitioningDelegate *strongTransDelegate; And then do this: theVC.modalPresentationStyle = UIModalPresentationCustom; theVC.transitioningDelegate = transDelegate; theVC.strongTransDelegate = transitionDelegate; All seems to work well. When the view controller is dismissed the transitioning delegate is deallocated. However I'm assuming the transitioningDelegate property on UIViewController was declared as weak for a reason? I don't want to accidentally create a retain cycle in some unforeseen circumstance. Documentation makes no mention on who should be the "owner" of the transitioning delegate?
