Access to AppDelegate methods from NSViewController

Question

I'm trying to execute a method present in AppDelegate from my NSViewController class. I tried this line to access to the AppDelegate :

let appDelegate = UIApplication.shared.delegate as! AppDelegate;

Without success : Use of unresolved identifier 'UIApplication'. Tried to import UIKit, doesn't works ... cause it's for IOS ?

PS : It's hard to learn how to develop in swift ... a lot of tutorials are for objective C, and the swifts can also be for IOS ...

Look at docs for `NSApplication`...anything UI* is iOS. Your problem is more about platform than language. — Phillip Mills, Jun 22 '17 at 13:38
I'm a noob ... would you please make an answer ? I'll accept it :) — Antoine, Jun 22 '17 at 13:42

NSViewController is clearly macOS.

In macOS you get the application delegate with

let appDelegate = NSApp.delegate as! AppDelegate

NSApp is a shortcut for NSApplication.shared

Weird that NSApplication.shared as! AppDelegate will fail, but NSApp works as expected. – Starwave Nov 13 '19 at 15:24
@Starwave It's not weird. You have to write `NSApplication.shared.delegate as! AppDelegate ` – vadian Nov 14 '19 at 08:07
