Activation Behavior of a Global Command Palette

Art Lasovsky:

To improve this, we can add NSApplicationDelegate to our app and set the activation policy to .prohibited in the applicationWillFinishLaunching(_:) method. Then, in the applicationDidFinishLaunching(_:) method, we can set the activation policy to .accessory(or .regular if we want the dock icon to be visible).

This way, the app will launch without stealing focus.

[…]

We override the close() method and add NSApp.hide() to deactivate the app after closing the window.

By overriding the cancelOperation(_:) and resignKey() methods, we ensure that our launcher will be closed when the user presses the Esc key or selects another window.
