I really need help. Can anyone decrypt the following message for me: Dear Developer, We identified one or more issues with a recent delivery for your app, "MYAPP" 2.0 (1200). Please correct the following issues, then upload again. ITMS-90288: Invalid Code Signing Entitlements - The entitlements in your app bundle signature do not match the ones that are contained in the provisioning profile. According to the provisioning profile, the bundle contains a key value that is not allowed: '' for the key 'com.apple.application-identifier' in 'MYAPP.app/Contents/Frameworks/libsqlite3s.dylib' ITMS-90286: Invalid Code Signing Entitlements - Your application bundle's signature contains code signing entitlements that are not supported on macOS. Specifically, value '' for key 'com.apple.application-identifier' in 'MYAPP.app/Contents/Frameworks/libsqlite3s.dylib' is not supported. This value should be a string starting with your TEAMID, followed by a dot '.', followed by the bundle identifier . The 2 dylibs are built by myself and for years I did not have this problem with submission. What should I do? Although I know something is wrong with entitlements/signature, but I have no clue at all on what I need to exactly.

I target my project to macOS version 10.10. Now I have an NSStackView in IB and I can set its distribution property in the inspector pane. But there is a yellow warning saying that the distribution property is available only on 10.11+. My question is - will my app crash if it runs on macOS 10.10?

I have an annoying problem with Xcode 14.2. After opening a project, Quick Help pane works normally. But once a debugging session ends, it stops working (showing nothing). Meanwhile ALT+CLICK won't work either (no response). After closing and re-opening the project Quick Help works again. Is there any workaround for this nuiance? I already went back to 13.14.1.

I cannot find any docs on this image name but I can select it from the dropdown list in IB. What is the mim macOS version for this name?

I think I can do this by creating a custom view overriding the following 2 methods: @implementation MyTextField - (BOOL)becomeFirstResponder { NSLog(@"%s: %@", __func__, self); return [super becomeFirstResponder]; //return YES; } - (BOOL)resignFirstResponder { NSLog(@"%s: %@", __func__, self); return [super resignFirstResponder]; //return YES; } @end But there is a gotcha - I always get successive become/resign. That is when I get becomeFirstResponder, I also get resignFirstResponder immediately. Note - I only have one MyTextField instance on my window. Is there another safe way to achieve my goal?

This is the first time I use KVO pattern. The code is quite simple but I could not get it working - the log method never gets run. What's wrong with my code? @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; [self.view.window addObserver:self forKeyPath:@"firstResponder" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:nil]; } - (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context { NSLog(@"%@", change); } @end

I am currently using Xcode 14.2 (14C18), but it has some glitches (which I don't want to enumerate here). I now want to revert back to an earlier older version. Any suggestions?

I really like to implement an overlay that is similar with what we have in NSDatePicker: I know most of the time, we just use what Apple gives us behind the curtain, but I really want to know if this even possible. Thanks!

I want to add "Show in Finder" in my app that is similar to the one in Xcode. How do I do this using objc?

In IB I connect a button to a VC and set the segue kind to 'Popover'. Now I have a problem. How do I get the NSPopover and its delegate? -(void)prepareForSegue:(NSStoryboardSegue *)segue sender:(id)sender {     NSLog(@"%s: %@", __func__, segue.destinationController);     NSViewController* vc = segue.destinationController; }

I am aware of the following approach: Add a custom view into a view in IB. Set the class of this custom view, say "MyDatePickerView". Now my datepicker view has a moderate complex UI, and I want to isolate its functionalities into a standalone XIB. Is it possible to do this in IB (I know I can do it in code)?

Got confused about these 2 methods. NSObject protocol has an isEqual: method. NSObject implements NSObject protocol but it does not have isEqual:, instead it has an isEqualTo: method. What's the magic behind the design? Or is the doc wrong? Should I implement both methods in a derived class?

I have a need to tell if 2 images are different by unimportant details. For example, one image is only slightly different than another because: *) It is a little stretched *) or it has 99% portion of another (only missing some pixels on borders) I wonder if there is an efficient algorithm to achieve my goal. Any suggestions are welcome.

I did searches on the Internet but could not find a definitive answer. The best thing I get is CGImageSourceCreateThumbnailAtIndex API function. But I don't know how create CGImageSource out of an NSImage object. Thanks for any suggestions.

I have a custom view that acts as a container for many NSImageViews that will be created dynamically on the fly. When the container view is resized (by parent window), some new subviews may be created and added to the container view, or some subviews may be removed because they are not fit into a smaller view. I have two ways to handle the 'disappearing' subviews. One way is to hide them, the other is to remove them from the container view. My concern is that - Is there a (big) performance difference between the two methods? Which is better?
