Double tap over collection view

Question

I have a UIViewController with a UITableView and a UICollectionView.   The way it works is that when I click on the TableView, the contents of the CollectionView has be changed and everything works fine.   However, when I add a UITapGestureRecognizer over the entire View for the double click, everything still works as it should, but the CollectionView loads significantly slower.

let tap = UITapGestureRecognizer(target: self, action: #selector(doubleTapped))
             tap.numberOfTapsRequired = 2
             tap.cancelsTouchesInView = false
             tap.delaysTouchesBegan = true
             view.addGestureRecognizer(tap)

The issue is the line: tap.delaysTouchesBegan = true If true, the CollectionView is slow. In case it's false, everything is fast, but double click doesn't work :(   Any experience, idea?
