You could use an NSTimer. Start or invalidate and restart the timer for 2 seconds in your textDidChange. Have the timer fire the findUser method when it actually pops.

    var debounceTimer: NSTimer?

@IBAction func test() {
    if let timer = debounceTimer {
        timer.invalidate()
    }
    debounceTimer = NSTimer(timeInterval: 2.0, target: self, selector: Selector("getUser"), userInfo: nil, repeats: false)
    NSRunLoop.currentRunLoop().addTimer(debounceTimer!, forMode: "NSDefaultRunLoopMode")
}

func getUser() {
    println("yeah")
}
