Create wait time in Swift

We want to wait a certain time, let use NSTimer.

Declare a count variable above viewDidLoad

var count=1

Copy this function in to above last close bracket.

func update(){

        count = count + 1

    if count==10{

            let vc = second()

            self.presentViewController(vc, animated: true, completion: nil)        }

    }

Add this line to inside viewDidLoad.

let time=NSTimer.scheduledTimerWithTimeInterval(1.0, target:self,  selector: "update",userInfo: nil, repeats: true)

We wait 10 seconds and open class second.

Another way is to create a delay function.

func delay(delay:Double, closure:()->()) {

dispatch_after(

dispatch_time(

DISPATCH_TIME_NOW,

Int64(delay * Double(NSEC_PER_SEC))

            ),

dispatch_get_main_queue(), closure)

    }

When want to wait 10 seconds, call function like this.

delay(10) {

let vc = third()

self.presentViewController(vc, animated: true, completion: nil)

  }
