Created April 1, 2015 23:31
Flashing the screen in Swift. Sticking this here because it took me a while to work out the right variable types and casting.
func flashScreen() {
let inDuration: CGDisplayFadeInterval = 0.5
let outDuration: CGDisplayFadeInterval = 0.5
let color = NSColor.redColor()
var fadeToken: CGDisplayFadeReservationToken = 0
let colorToUse = color.colorUsingColorSpaceName(NSCalibratedRGBColorSpace)!
let err = CGAcquireDisplayFadeReservation(inDuration + outDuration, &fadeToken)
if Int(err) != Int(kCGErrorSuccess.value) {
NSLog("Error acquiring fade reservation")
