After detecting the UIImageView tap with Swift, I want to transition to the detail screen.

I set up two UI ImageViews on the storyboard, each with the same image.
I set the tag to 1 and 2 respectively.

@IBOutlet weak variv2:UIImageView!

@IBOutlet weak variv:UIImageView!

override func viewDidLoad(){
    super.viewDidLoad()
    varimg = UIImage(named: "paint2.png")
    iv.image=img
    iv2.image=img
}
override functouchesBegan(touches:NSSet, withEvent:UIEvent) {
        var touch = touches.anyObject() as UITouch
        println(touch.view.tag)
        switch(touch.view.tag){
        case1:
            break
        case2:
            break
        default:
            break
        }
    }

As a result, 1,2 will be output to LOG when UIImageView is tapped, and 0 will be output when pressed otherwise.

What I want to do is to tap UIImageView and move to the next screen, and I want to release a large image of the tapped image.
It's like a detail screen.
Please.

There are several techniques, but UIGestureRecognizer, UITapGesConsider a pattern that utilizes the textureRecognizer.

override func viewDidLoad(){
    super.viewDidLoad()
    let img = UIImage(named: "paint2.png")
    iv.image=img
    iv2.image=img

    let gesture=UITapGestureRecognizer(target:self, action "didClickImageView:")
    iv.addGestureRecognizer(gesture)
    iv2.addGestureRecognizer(gesture)
}

func didClickImageView (recognizer: UIGestureRecognizer) {
    iflet imageView=recognizer.view as?UIImageView{
        let image=imageView.image
        let nextViewController=/**The following UIViewController instances*/
        nextViewController.image=iamge
        /** Transition to netViewController*/
    }
}
