How to trigger button action on leftMouseDown in Swift, Mac OSX, Cocoa

Question

I want to trigger a button on left mouse down in my mac osx app using swift.

This is the way to do it in Objective-C

[myButton sendActionOn:NSLeftMouseDownMask];

I can't figure out how to do it in Swift. Can anybody help me out with my problem?

Thanks!

Don't have Xcode with me but it should have been the same in Swift: `myButton.sendActionOn(NSLeftMouseDownMask)` — Code Different, Jul 28 '15 at 21:21
I'm getting the error message: Use of unresolved identifier 'NSLeftMouseDownMask' if i'm trying your solution. Or do I have to import anything? — stefOCDP, Jul 28 '15 at 21:27
Then I'm getting this error message: Cannot invoke 'sendActionOn' with an argument list of type '(NSEventType)' — stefOCDP, Jul 28 '15 at 21:34

After a bit of fiddling in Xcode, this is what worked for me (Swift 2.0):

myButton.sendActionOn(Int(NSEventMask.LeftMouseDownMask.rawValue))

Swift 5:

myButton.sendAction(on: NSEvent.EventTypeMask.leftMouseDown)
