Xcode 10.2 Swift 5:

override func viewDidLoad() {
    super.viewDidLoad()
    // ...
    Timer.scheduledTimer(timeInterval: 8.0, target: self, selector: Selector(("your @obcj func name")), userInfo: nil, repeats: true)
}

//Anywhere in the same view controller to stop the loop:
Timer.cancelPreviousPerformRequests(withTarget: your @obcj func name())
