Scrolling with two fingers with a UIScrollView

Question

I have an app where my main view accepts both touchesBegan and touchesMoved, and therefore takes in single finger touches, and drags. I want to im

Answer 1

I put this in the viewDidLoad method and this accomplishes the scroll view handling the two touch pan behavior and another pan gesture handler handling the one touch pan behavior -->

scrollView.panGestureRecognizer.minimumNumberOfTouches = 2

let panGR = UIPanGestureRecognizer(target: self, action: #selector(ViewController.handlePan(_:)))
panGR.minimumNumberOfTouches = 1
panGR.maximumNumberOfTouches = 1

scrollView.gestureRecognizers?.append(panGR)

and in the handlePan method which is a function attached to the ViewController there is simply a print statement to verify that the method is being entered -->

@IBAction func handlePan(_ sender: UIPanGestureRecognizer) {
    print("Entered handlePan numberOfTuoches: \(sender.numberOfTouches)")
}
