iOS 13 Segmented Control: Remove swipe gesture to select segment

Question

TLDR: How to remove the swipe/pan gesture recognizer for UISegmentedControl on iOS 13?

Hi, on iOS 13, lots changed with UISegmentedControl. Mostly, the changes were

Answer 1

I upgraded @Aystub's answer. You can only allow UITapGestureRecogniger to select a segment.

class NoSwipeSegmentedControl: UISegmentedControl {
        override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {

            if(gestureRecognizer.isKind(of: UITapGestureRecognizer.self)){
                return false
            }else{
                return true
            }

       }
}

I have a similar setup (UISegmentedControl inside a UIScrollView bc it's too long and the client didn't want to compress the content to fit). This worked for me (Built on Xcode 11.1):

class NoSwipeSegmentedControl: UISegmentedControl {

    override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }
}

Then set the class of my UISegmentedControl to that. In my app this only prevents the swipe-to-select gesture on UISegmentedControl objects embedded within a UIScrollView. If it is not in a UIScrollView nothing behaves any differently. Which makes sense because gestureRecognizerShouldBegin() returns true by default. So why this allows the UIScrollView to take priority on the swipe gesture, I have no idea. But hope it helps.

Using this code allows the segmented control to still be swiped UNLESS it's embedded in a UIScrollView. This is the smallest tradeoff in functionality in my opinion

final class NoSwipeSegmentedControl: UISegmentedControl {

    override func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
        guard type(of: gestureRecognizer).description() != "UIScrollViewPanGestureRecognizer" else {
            return true
        }
        return super.gestureRecognizerShouldBegin(gestureRecognizer)
    }

}
