Using Xcode 12.5.1 I have 2 properties on an object @property NSMutableArray *mutA1; @property NSMutableArray *mutA2; During initialization I do this: self.mutA1 = [NSMutableArray arrayWithCapacity:10]; self.mutA2 = [NSMutableArray arrayWithCapacity:10]; The first assignment works fine but I get an error on the second assignment! Exception NSException * "[<__NSArrayM 0x6000037f1ec0> addObserver:forKeyPath:options:context:] is not supported. Key path: count" 0x00006000037d74e0 What can explain this? I am just stumped!! Thank you for any help! Steve

Could someone please clarify how to access SmartGroups using the CNContacts framework?

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

I'm building an app for deployment on iPhone, iPad and Mac Catalyst. I am using Automatic Code Signing. Project build without a single warning of any kind... Debugging and running the app on both iPhone and iPad is working fine both in the simulators as well as on various test devices. I have now turned to debugging on my Mac (M1Pro-MBP). I have run Clean many times....When I set the run destination to My Mac Catalyst and run I immediately see a dialog stating: "The LaunchServices launcher has returned an error. Please check the system logs for the underlying cause of the error." There is button to reveal details. Those details are shown below. At the moment I am under the impression that this must be a relatively straightforward configuration issue which I have overlooked.... The app does contain an action and if I build and run only the action with Mac Catalyst as the destination it runs fine.. I only hit the error when I try to run the container app with embedded action with my Mac as the run destination.... Can anyone shed any light on this matter? All thoughts appreciated!

Folks; I have a sandboxed macOS app that provides text handling via a service. This app has been for sale in the Mac App Store for several years. The basic mechanics of the service work just fine… To set the scene: user opens a file in some fashion user makes a text selection within this open file user invokes my app’s service In the course of development of this service, I now have established an NSURL (file) for the user’s document. However, when I later attempt to open this url I get a sandbox error: client lacks entitlements? for path: …. NOTE: It does not matter where the file is located! My app already has this entitlement: com.apple.security.files.user-selected.read-write My question: Is there an entitlement that will permit me to programmatically open this fileURL?

macOS 10.15.6 - Xcode 11.7 This app has been in App Store for over a year. The code in question here has been working and tested. It no longer functions as before... Attempting to test a brand new install using a sandbox account on a Mac. Receipt validation is run in main.m with: ...             return NSApplicationMain(argc, (const char **)argv);         } } @catch (NSException *e) {         exit(173);     } Delete the appropriate folder in ~/../Containers Clean - Build - Run When Run the exception is trapped and the prompt for sandbox credentials is shown. Upon completion of the credentials I receive the 'app is damaged and cannot be opened...' I have logged out, I have rebooted, I have tried with a different sandbox account - all to no avail. Any thoughts would be deeply appreciated! Thanks for your time! Steve
