I need to store some data of my application in system keychain which should to accessible to all the users in the system. Here is the below sample code : // Create a SecAccessControlRef for a keychain item with access control SecAccessControlRef accessControl = SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlocked, kSecAccessControlUserPresence, NULL ); // Define a query dictionary for a keychain item NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: @"MyService", (__bridge id)kSecAttrAccount: @"MyAccount", (__bridge id)kSecValueData: [@"MyPassword" dataUsingEncoding:NSUTF8StringEncoding], (__bridge id)kSecAttrAccessControl: (__bridge_transfer id)accessControl, }; // Add the keychain item to the default keychain (login keychain) OSStatus status = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (status != errSecSuccess) { NSLog(@"Error adding keychain item: %d", (int)status); } I tried using SecKeychainOpen to access the system keychain but SecKeychainOpen is deprecated and I could not find any equivalent latest API to support that. SecKeychainRef systemKeychain; OSStatus status = SecKeychainOpen("/Library/Keychains/System.keychain", &systemKeychain); if (status != errSecSuccess) { NSLog(@"Error opening system keychain: %d", status); } else { SecAccessControlRef accessControl = SecAccessControlCreateWithFlags( kCFAllocatorDefault, kSecAttrAccessibleWhenUnlocked, kSecAccessControlUserPresence, NULL ); NSDictionary *query = @{ (__bridge id)kSecClass: (__bridge id)kSecClassGenericPassword, (__bridge id)kSecAttrService: @"MyService", (__bridge id)kSecAttrAccount: @"MyAccount", (__bridge id)kSecValueData: [@"MyPassword" dataUsingEncoding:NSUTF8StringEncoding], (__bridge id)kSecUseKeychain: (__bridge id)systemKeychain, (__bridge id)kSecAttrAccessControl: (__bridge_transfer id)accessControl, }; // Add the keychain item to the system keychain status = SecItemAdd((__bridge CFDictionaryRef)query, NULL); if (status != errSecSuccess) { NSLog(@"Error adding keychain item to system keychain: %d", (int)status); } if (systemKeychain) { CFRelease(systemKeychain); } } ANY suggestions will be helpful, Please help!

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, 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?

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];

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.

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.

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.

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

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

In the context of a system utility that reports OS stats periodically, the security type for a connected WiFi network could be obtained with Core WLAN via CWInterface.security. This used to work up to Ventur; howver, after upgrading to Sonoma, cwInterface.security now returns kCWSecurityUnknown. In other posts, I have read about changes in how Core WLAN works which are related to Sonoma. How can I determine the security type for a connected WiFi network on Sonoma? It would be preferable if the suggested approach would also work on previous macOS versions as well. Many thanks in advance! :-)

as I open the pop-up menu and move the mouse before that opened, MouseEntered Event and MouseExited Event are called when mouse moved. The following trackingAreas options are inclued in the view in pop-up area. NSTrackingInVisibleRect, NSTrackingMouseEnteredAndExited, NSTrackingMouseMoved, NSTrackingActiveInKeyWindow LocationInWindow of MouseExitedEvent seem to be incorrect. This problems does not occur in the following cases. Do not move the mouse until the popup is fully opened. Left mouse button down on pop-up area. Move the mouse out of the pop-up area. This issue occurs in Sonoma(MacOS14.0) and later. I would like to know if this is a code issue or a bug in the OS Version.

In iOS 17 Im getting following error : Alert NSInternalinconsistencyException-UlViewController is missing its initial trait collection populated during initialization. This is a serious bug, likely caused by accessing properties or methods on the view controller before calling a UlViewController initializer.

Hello! I need assistance writing an Objective-C function that can interface with the game engine Unity and listen for changes in built-in output and see if headphones are or are not currently connected to a Mac device.

I am developing an mobile application on objective C. I use UIImageView a lot to display several images on my app. It works fine up to iOS 16. Starting on iOS 17 both on a real iPhone and on the simulators the images don't show. It is like UIImageView does not load the images on iOS17. Is there anything new on iOS17 regarding how to use UIImageView?

In iOS 17, I am having an issue where UIPopoverPresentationControllers are not retaining the preferred size of the UIViewController they contain. The following method uses a UIPopoverPresentationController popoverVC to display a UIViewController contentVC from a UIView view anchor location frame. + (void) showDialogiPad:(UIViewController *)contentVC fromPresentingVC:(UIViewController *)presentingVC inView:(UIView *)view atFrame:(CGRect)frame withDirection:(UIPopoverArrowDirection)direction { // Set content view controller size contentVC.preferredContentSize = contentVC.view.frame.size; // Choose the presentation style in which the content is // displayed in a popover view contentVC.modalPresentationStyle = UIModalPresentationPopover; // Get a popover presentation controller UIPopoverPresentationController *popoverVC = contentVC.popoverPresentationController; // Set the popover size and anchor location contentVC.popoverPresentationController.sourceRect = frame; contentVC.popoverPresentationController.sourceView = view; // Set the arrow direction for the popover popoverVC.permittedArrowDirections = direction; // Present the popover presentation controller [presentingVC presentViewController:contentVC animated:YES completion:nil]; } Prior to iOS 17, the code displayed the popover as expected as shown here: The issue now however is since the update to iOS 17, the popover is now squashed and displayed as: A few observations: The popover dialog actually displays properly the first time you open it. Every subsequent time you open it, it is squashed. When I comment out the line that sets the preferredContentSize, the popover opens at the max size every time - so it shows all the content but it is not set to the size I want it to be. If I leave preferredContentSize as is but change modalPresentationStyle to UIModalPresentationFormSheet, the size of the popover is correct but the popover always presents in the middle of the screen.

I am building a project which has swift, cpp and objective - c files. Till now the app was working fine. But now Since the app is built using the newer Xcode version ie Xcode 15, the app is crashing in the BigSur( MacOS 11) using arm64 processor. It works fine in all other OS including OS 11 with x86_64 processor. When I checked the reason for the crash, the crash report points at the place where we created cpp instances in objective c file. My code is as follows _deviceList = new AudioDeviceList(false); // AudioDeviceList is the cpp class and I am creating instance for this in Objective c file mBassTrebleLevelLeft = new BassTreble(512); // BassTreble is the cpp class and I am creating instance for this in Objective c file The crash points at these lines. Can anyone please help me why there is issue with Xcode 15 on creation of cpp instance?
