Swipe to open new screen Swift

We want user can swipe screen to open new class, use this function.

func tap (g:UIGestureRecognizer) {

let vc = second()

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

 }

Add this line in to viewDidLoad.

let t = UIPanGestureRecognizer(target:self, action:#selector(tap(_:)))

view.addGestureRecognizer(t)

On new class, if want swipe back to previous screen, use this.

func tap (g:UIGestureRecognizer) {

self.dismissViewControllerAnimated(true, completion: nil)

    }

Add to viewDidLoad.

let t2 = UIPanGestureRecognizer(target:self, action:#selector(second.tap(_:)))

view.addGestureRecognizer(t2)

}
