Override keyDown: and keyUp: method.

-(void)keyUp:(NSEvent*)event -(void)keyDown:(NSEvent*)event

and

- (BOOL)acceptsFirstResponder { return YES; }

In subclass of NSViewController you should refer Cocoa Event-Handling Guide .

If you are trying to simply get an event for escape, use this instead:

override var acceptsFirstResponder: Bool { return true } override func cancelOperation(_ sender: Any?) { // The user pressed escape }

Setting window to "Auto Recalculates View Loop" in Inteface Builder has worked for me.
