Swift version

        if UIDevice.currentDevice().userInterfaceIdiom == .Pad{
            label.text = "iPad"
        }else{
            
            var detectionSize:CGFloat = 0
            
            if self.interfaceOrientation == .Portrait{
                detectionSize = self.view.bounds.height
            }else{
                detectionSize = self.view.bounds.width
            }
            
            switch detectionSize{
            case 480:
                label.text = "iPhone 4S"
            case 568:
                label.text = "iPhone 5/5S"
            case 667:
                label.text = "iPhone 6"
            case 736:
                label.text = "iPhone 6 Plus"
            default:
