macos - quitting xcode cocoa swift app

Question

I have written my first swift OS/X application in XCode 6. It all works except I cannot figure out how to exit the app. I have a button to exit and the ExitNow function defined as follows:

@IBAction func ExitNow(sender: AnyObject) {
    // ???
}

I cannot figure out what the code would be. By searching online I've found various options, but they were either in Objective C or too general for me to comprehend. I would appreciate an example which would behave the same way as cmd-Q.

Answer 1

You should be able to just call terminate on the global NSApp object.

@IBAction func ExitNow(sender: AnyObject) {
    NSApplication.sharedApplication().terminate(self)
}

Edit With Swift 3 the code is now:

@IBAction func ExitNow(sender: AnyObject) {
    NSApplication.shared().terminate(self)
}

Edit 2 With Swift 4 & 5 the code is now:

@IBAction func ExitNow(sender: AnyObject) {
    NSApplication.shared.terminate(self)
}
