How to listen to global hotkeys with Swift in an OS X app?

Question

I\'m trying to have a handler in my Mac OS X app written in Swift for a global (system-wide) hotkey combo but I just cannot find proper documentation for it. I\'ve read that

Answer 1

A quick Swift 3 update for the setup:

let opts = NSDictionary(object: kCFBooleanTrue, forKey: kAXTrustedCheckOptionPrompt.takeUnretainedValue() as NSString) as CFDictionary

guard AXIsProcessTrustedWithOptions(opts) == true else { return }

NSEvent.addGlobalMonitorForEvents(matching: .keyDown, handler: self.handler)
