如何从 UIViewController 调用 AppDelegate 方法

Question

In my appDelegate.m file I have this method

- (void) goToRN {
   [RCTKeyWindow().rootViewController dismissViewControllerAnimated:true completion:nil];
}

and I would like to call this method from my ConsentViewController.swift file like: AppDelegate().goToRN()

but I'm getting this error: Value of type 'AppDelegate' has no member 'goToRN'

You can get it from the application global variable:

NSApp.delegate
