collection view pan gesture

I have a collection view cell: class MyTripsCollectionViewCell: UICollectionViewCell, UIGestureRecognizerDelegate { that implements the UIGestureRecognizerDelegate I added pan gesture recognizer : override func awakeFromNib() { let gestureRecognizer = UIPanGestureRecognizer(target: self, action:#selector(MyTripsCollectionViewCell.handlePan(_:))) gestureRecognizer.delegate = self self.addGestureRecognizer(gestureRecognizer) } below is the handlePane Function : func handlePan(recognizer: UIPanGestureRecognizer) { if (recognizer.state == UIGestureRecognizerState.Began) { // if the gesture has just started, record the current centre location originalCenter = self.center } if (recognizer.state == UIGestureRecognizerState.Changed) { // translate the center if recognizer.isLeft(self) { let translation = recognizer.translationInView(self) if self.center.x >= 150 { self.center = CGPointMake(originalCenter.x + translation.x, originalCenter.y); } // determine whether the item has been dragged far enough to initiate a delete / complete deleteOnDragRelease = self.frame.origin.x == 150 ? false : true } } // 3 if (recognizer.state == UIGestureRecognizerState.Ended) { // the frame this cell would have had before being dragged let originalFrame = CGRectMake(0, self.frame.origin.y, self.bounds.size.width, self.bounds.size.height); if (!deleteOnDragRelease) { // if the item is not being deleted, snap back to the original location UIView.animateWithDuration(0.2) { self.frame = originalFrame; } } } } In this code I am trying to move the collection view cell from left to right,until it's cente reach 150 point, this work now when I move my finger slowly, but the problem is when I move my finger very fast the translation take a large value which make the cell move more than 150 and then stop cause it make the condition be true so how I can fix the problem of the speed of panning?
