In Swift this can be achieved using below code

class DragView: UIView { 
  // Starting center position
  var initialCenter: CGPoint?

  override func didMoveToWindow() {
    super.didMoveToWindow()
    // Add longPress gesture recognizer
    let longPress = UILongPressGestureRecognizer(target: self, action: #selector(longPressAction(gesture:)))
    addGestureRecognizer(longPress)
  }

  // Handle longPress action
  func longPressAction(gesture: UILongPressGestureRecognizer) {
    if gesture.state == .began {
        guard let view = gesture.view else {
            return
        }
        initialCenter = gesture.location(in: view.superview)
    }
    else if gesture.state == .changed {
        guard let originalCenter = initialCenter else {
            return
        }

        guard let view = gesture.view else {
            return
        }

        let point = gesture.location(in: view.superview)

        // Calculate new center position
        var newCenter = view.center;
        newCenter.x += point.x - originalCenter.x;
        newCenter.y += point.y - originalCenter.y;

        // Update view center
        view.center = newCenter
    }
    else if gesture.state == .ended {
       ...
    }
}
