Toolbar

NSToolbar (Mac API) UIWindowScene.titlebar.toolbar — access

func scene(_ scene: UIScene,
			willConnectTo session: UISceneSession,
			options connectionOptions: 				UIScene.ConnectionOptions) {

Print global NSUserDefaults:

defaults read -g

Write a date via Terminal:

defaults write [com.myapp] [theKey] -date [2019-07-08T17:08:48Z] Writes 8th of July, 2019, 17:08:48 for theKey for domain com.myapp

Nil & NSUserDefaults

Not friends. Even with NSNull. To remove a key-value pair, call removeObject:forKey:
