Piping NSEventMask together in 'addLocalMonitorForEventsMatchingMask'

Question

I have the following code for listening for mouse events outside the view (subclass of NSView). This works great as it is, but I cannot figure out how to pipe the NSEventMasks together. I basically want to have the same event listener fire on NSEventMask.LeftMouseDownMask, NSEventMask.RightMouseDownMask and NSEventMask.OtherMouseDownMask.

Does anyone know how to pipe them together or if it's even possible in Swift?

Working code

localMouseEventListener = NSEvent.addLocalMonitorForEventsMatchingMask(NSEventMask.LeftMouseDownMask) { (event: NSEvent) -> NSEvent? in

        // Event handling...

        return event
    }

This answer might help you.

In short you can now use arrays, so this seems to make the compiler happy:

localMouseEventListener = NSEvent.addLocalMonitorForEventsMatchingMask([.LeftMouseDownMask, .RightMouseDownMask, .OtherMouseDownMask]) { (event: NSEvent) -> NSEvent? in

    // Event handling...

    return event
}
