implementing custom keyboard shortcuts not firing in macOS 13.6 app using AppKit
I need help solving I'm working on a project and hit a roadblock. I'm working with a persistent scenario where custom keyboard shortcuts are not triggering their associated actions in my macOS 13.6 application built with AppKit. I've set up the shortcuts in my menu items, and they appear correctly in the menu, but when I use the keyboard combination, nothing happens. I've verified that the responder chain is intact, and the actions are correctly linked to their selectors. I've implemented the shortcuts as follows: ```swift let menuItem = NSMenuItem(title: "My Action", action: #selector(myAction), keyEquivalent: "m") menuItem.keyEquivalentModifierMask = [.command, .shift] mainMenu.addItem(menuItem) ``` The `myAction` selector is defined like this: ```swift @objc func myAction() { print("Action triggered") } ``` I've also tried ensuring that the window is first responder when I press the shortcut, but even then, the action does not get called. My application is a single window app, and I'm not using any modal dialogs that could be intercepting the keystrokes. Moreover, when I check the console logs, I don't see any relevant behavior messages that could give me a hint about what might be wrong. I've looked into using `NSApplication.shared.keyWindow` to debug whether the key window is correctly set, and it seems to be fine. Are there any specific scenarios in which custom keyboard shortcuts might unexpected result to work in macOS applications? Any insights into debugging this scenario or best practices for implementing keyboard shortcuts would be much appreciated. My development environment is Linux. Any ideas how to fix this? My development environment is Windows 11.
