My app saves the file URLs obtained from UIDocumentPickerViewController as bookmark data and reads them on the "history screen". In the "history screen", whenever viewWillAppear is called in ViewController, URLByResolveBookmarkData is called for all bookmarks to check if the file has been deleted or moved. (Please see code below) - (void)refresh { NSManagedObjectContext* context = self.managedObjectContext; // read all bookmarks NSArray<HistoryItem*>* all = [self histories]; [all enumerateObjectsUsingBlock:^(HistoryItem * _Nonnull item, NSUInteger idx, BOOL * _Nonnull stop) { BOOL isStale; NSURL* url = [NSURL URLByResolvingBookmarkData: item.bookmark options: 0 relativeToURL: nil bookmarkDataIsStale: &isStale error: nil]; if(url == nil) { // file is deleted [context deleteObject: item]; } else { item.filename = url.lastPathComponent; if(isStale) { // file is moved NSData *data = [url bookmarkDataWithOptions: 0 includingResourceValuesForKeys: 0 relativeToURL: nil error: nil]; if(data != nil) { item.bookmark = data; } } } }]; [context save: nil]; } Then, after many calls to viewWillAppear, calling startAccessingSecurityScopedResource on the URL obtained by URLByResolvingBookmarkData returns NO. I suspect that URLByResolveBookmarkData is consuming some resources, because the problem reproduces even if I change the code inside the block to only call URLByResolveBookmarkData, and it doesn't reproduce when I empty the block. Does URLByResolvingBookmarkData consume any resources? If so, how do I release the consumed resources? OS: iOS 15 Xcode: 15.0

Will there be any restrictions/Limitations on publishing iOS applications that internally run Python scripts on the App Store during the Apple Review process?

I am looking for a way to run the .py (python file) inside the iOS application, but I am unable to find a way for iOS apps. but for MAC I see PythonKit support. Appreciate any help.

Hello, Our application uses following code to activate itself: void BecomeFrontMostApp() { @autoreleasepool { if ([NSApp isActive] == YES) return; [[NSRunningApplication currentApplication] activateWithOptions: NSApplicationActivateIgnoringOtherApps | NSApplicationActivateAllWindows ]; } } Code works on Ventura and previous OS versions but not on Sonoma. On Sonoma application does not come to foreground but instead dock icon starts jumping same way when calling: [NSApp requestUserAttention: NSCriticalRequest]; And activateWithOptions returns false. I checked activationPolicy on the app running on Sonoma - it is NSApplicationActivationPolicyRegular Any ideas how to fix this appreciated.

This status is essential for generating simulated CGEvents. Games often use this API to implement cursor lock. If we send CGEvents with a moving position, it's possible for the cursor to move outside the game window and cause the game window to become inactive. If we don't send CGEvents with updated positions, we can only control the mouse within the game but not in other windows or the desktop.

Updating to MacOS 12, in Objective C, I get the above warning regarding changing kUTTypeJPEG to UTTypeJPEG in two places The old code still works but even after the @import UniformTypeIdentifiers changing kUTTypeJPEG to UTTypeJPEG with various types, e.g. CFString, CFStringRef, and that UTTYPE doesn't bridge???, etc. (I am obviously clueless about this) I get the compiler warnings to go away but then the program crashes. How do I fix these? Something to do with ARC or bridging??? CGImageDestinationRef destinationRef = CGImageDestinationCreateWithURL((__bridge CFURLRef)theURL, (NSString *)kUTTypeJPEG, 1, NULL); NSDictionary *imageSourceCreationOptions = [NSDictionary dictionaryWithObjectsAndKeys: kUTTypeJPEG,(NSString *)kCGImageSourceTypeIdentifierHint, (NSNumber *)kCFBooleanTrue, (NSString *)kCGImageSourceShouldCache, (NSNumber *)kCFBooleanTrue, (NSString *)kCGImageSourceShouldAllowFloat, nil];

Hi, My app supports VoiceOver and VoiceControl, and I find it hard or perhaps even impossible to support both when it comes to grouping accessibility elements. I have an element containing multiple subviews, and I want to define it as a group of accessibility custom actions to enhance VoiceOver navigation. (So that the user can focus on the entire element, and just swipe up or down if they want to activate one of its subviews as a custom action). To do that, I'm setting isAccessibilityElement to YES and I'm using accessibilityCustomActions where I create a custom action for each of this element's subviews. This works fine and presents the accessibility custom actions as expected. The struggle comes when I try to combine it with Voice Control. Since the element contains multiple subviews, I want each of these subviews to be accessible when using Voice Control with item numbers, for example. Instead, Voice Control is setting a number only on the entire element, ignoring its subviews. This is not functional because each of these subviews performs a different action when activating it. I found that VoiceControl is only numbering subviews when the parent's isAccessibilityElement is set to NO. And indeed, when changing to NO, the subviews are getting numbered, but the custom actions group break, and VoiceOver treats each element as a separate accessibility element. So I can't use accessibilityCustomActions AND supporting VoiceControl. Is this an intended behavior defined by Apple? Or, is there anyway I can support them both?

Is there a way to customize the context menu that pops up when right clicking on a toolbar (or the title bar of the window containing it)? As of Sonoma, the steps that worked (described here: https://developer.apple.com/forums/thread/21887) up to Ventura no longer work. I'm developing in Objective-C.

Hi all, Our Objective-C project has quite a few Swift submodule that are linked with static Mach-O. The submodules are built and used in Objective-C files (.m, .mm) using the syntax #import <MyModule/MyModule-Swift.h> Since Xcode 14.3 and the early versions of Xcode 15.0, whenever I make any code changes in the .m .mm files (even just a space), all files using the Swift submodules are rebuilt. During my checks, I noticed the generated header of the submodules (MyModule-Swift.h) is regenerated even when its content hasn't changed. The modification time of the header file leads to the rebuilding of all Objective-C files. Of course, our project has a clean build when importing *-Swift.h in the .pch file, sometimes errors are thrown due to header changes during the build process. This behavior was not present in Xcode 14.2. More info I've tried configuring some flags in the Build settings, but they didn't work. Does anyone have any solutions to suggest for fixing this issue and saving our project ? :( Thanks!

Now that live previews are available in UIKit (source: https://developer.apple.com/wwdc23/10252) I was wondering how to get a UIViewController from Objective-C. The Swift macro looks like this: #Preview { var controller = SomeViewController() return controller; } Is there a way to get a live preview for UIViewControllers/UIViews written in Objective-C (other than wrapping it as a child view controller in an empty swift view controller)?

I'm trying to simply set my audio to the iPhone earpiece. No success, this seems like it would work. Using iOS 17 on an iPhone 15 Pro. It doesn't throw any errors. Any advice appreciated. @implementation AudioTogglePlugin - (void)setAudioMode:(CDVInvokedUrlCommand *)command { NSLog(@"... audiotoggle test ..."); NSError* err; AVAudioSession *session = [AVAudioSession sharedInstance]; [session setCategory:AVAudioSessionCategoryPlayAndRecord mode:AVAudioSessionModeVoiceChat options:AVAudioSessionCategoryOptionMixWithOthers error:NULL]; [session overrideOutputAudioPort:AVAudioSessionPortOverrideNone error:&err]; [session setActive:YES error:NULL]; NSLog(@"... audiotoggle error ... %@", err); NSLog(@"... audiotoggle route ... %@", [session currentRoute]); } @end The audio route stays on "Speaker": inputs = ( "<AVAudioSessionPortDescription: 0x283ae0d50, type = MicrophoneBuiltIn; name = iPhone Microphone; UID = Built-In Microphone; selectedDataSource = Front>" ); outputs = ( "<AVAudioSessionPortDescription: 0x283ae0dd0, type = Speaker; name = Speaker; UID = Speaker; selectedDataSource = (null)>" )>

Hi there, I am currently facing an issue with PDFKit page rendering. In one of my application, I have to open annoted PDF for reading and when user tap on particular annotation, I have to jump certain number of pages in same PDF to open the new desired page. Example: User is on page 2 and when user tap on menu button, I need to navigate directly on page number 8. With above scenario, my application takes a while to load page number 8 and User can see white screen before loading PDF page. When I checked console log, I can see following as an error. F.I: App requires to use usePageViewController for pagination. I am using as per following: _pdfView = [[PDFView alloc] initWithFrame:[UIScreen mainScreen].bounds]; [view addSubview:self.pdfView]; self.pdfView.delegate = self; [self.pdfView setAutoScales:true]; [self.pdfView setDisplayDirection:kPDFDisplayDirectionHorizontal]; [self.pdfView usePageViewController:true withViewOptions:nil]; [self.pdfView setBackgroundColor:UIColor.whiteColor]; Warning: Unable to complete drawing page index 24 on time as a request to forceUpdateActivePageIndex:withMaxDuration: 0.02 I hope if someone can help me on that Thanks.

Hi Team, I have been recently working on MacOS native application which interactes with Native API's to fetch SSID but recently this below mentioned API is returning nil as response on Sonoma OS Version. Below is the Objective - C for code reference CWWiFiClient *client = [CWWiFiClient sharedWiFiClient]; CWInterface *interface = [client interface]; NSString *ssid = [interface ssid]; I'm referring to following API - https://developer.apple.com/documentation/corewlan/cwwificlient?language=objc And trying to retrieve ssid https://developer.apple.com/documentation/corewlan/cwinterface?language=objc Note : The API is working on MacOS 13.0+ version and this seems to have broken in 14.0+ version Could you please provide us more details on the API issue, or any alternatives that can be followed, because from the documentation the above code seems to be a valid operation and nothing that is deprecated or restricted.

iOS app targeting iOS 15.5 has been working fine up to iOS 17 Beta (21A5326a). With iOS 17 RC (21A329) it is now crashing on launch. Anybody experiencing similar issue?

Why kVK_F2 is not equivalent to constant NSF2FunctionKey for F2 key press event, What is equivalent constant of kVK_F2, since carbon framework is deprecated. When I printed the keyCode, The [Event keyCode] against NSF2FunctionKey is 63237(0xF705) whereas for kVK_F2, it prints is 120 which is 0x78. 0x78 seems to be the standard keyboard value for F2 key. Sample code : //@property (nonatomic, strong) id eventMonitor; NSEvent* (^handler)(NSEvent*) = ^(NSEvent *theEvent) { NSEvent *result = theEvent; NSUInteger flags = [theEvent modifierFlags] &amp; NSEventModifierFlagDeviceIndependentFlagsMask; if ((flags &amp; NSEventModifierFlagFunction) &amp;&amp; (flags &amp; NSEventModifierFlagCommand) &amp;&amp; ([theEvent keyCode] == NSF2FunctionKey)) { NSLog(@"Command + F2 key pressed."); } return result; }; _eventMonitor = [NSEvent addLocalMonitorForEventsMatchingMask:(NSEventModifierFlagFunction | NSEventMaskKeyDown) handler:handler];

Hello all, I have an application which retrieves URL from browser using accessibility. From time to time I am having this crash and I don't know the reason for it. Could you please help me? This is the stacktrace: It is happening on MacOS 13.5 and it happens on an application built for x86_64 and arm64

Calling loadFileRepresentationForTypeIdentifier sometimes returns an empty file, the URL params is filled with a path where a file exists, however it contains empty content. My app is released on the store and this error happens 1.5% of the time my users pick an image / video from their gallery using the UIImagePickerControllerDelegate. I was able to reproduce this bug and here is a screenshot of XCode in debug mode so you can see that the file is empty right after calling loadFileRepresentationForTypeIdentifier I'm using XCode 14.3.1, a real iPhone 12 with iOS 16.3.1 and coding in Objective-C. Step to repro : 1- Capture a live photo with your device 2- Pick this photo from your gallery using UIImagePickerControllerDelegate -> didFinishPicking 3- Grab the item provider and call provider loadFileRepresentationForTypeIdentifier:@"public.jpeg" 4- Inside the completion handler check the file size of the URL provided in the parameters It is 1.5% repro, so to repro in local I had to take hundreds of live photos. But with patience, it happens and you can debug. Note: Calling a second time loadFileRepresentationForTypeIdentifier:@"public.jpeg" inside the completionHandler returns a URL pointing to a real file with existing content, thus there might be some race conditions somewhere. Do you have any workarounds?
