So I experience crash in UItextview while user interacts with URL link there. All crash reports have iOS version 11 only. This looks like well-known bug in iOS 9, but there

Answer 1

A crash is caused by a UIDragInteraction/UITextDragAssistant on iOS 11.0 and 11.1. It is fixed on iOS 11.2. Subclassing your UITextView and disabling drag and drop gestures will prevent the crash for any iOS version:

class NoDragDropTextView: UITextView {

    override func addGestureRecognizer(_ gestureRecognizer: UIGestureRecognizer) {

        // required to prevent drag and drop gestures
        // also prevents a crash on iOS 11.0-11.1
        gestureRecognizer.isEnabled = false

        super.addGestureRecognizer(gestureRecognizer)
    }
}
