How to change the size of a popover

Question

I\'m having trouble changing the size of my popover presentation. Here is what I have so far

 override func prepareForSegue(segue: UIStoryboardSegue, sender:         


        

Answer 1

Using Auto Layout

It may be worth mentioning that you can use layout constraints instead of setting preferredContentSize to specific values. To do so,

1. Add this to your view controller:

   override func viewWillAppear(_ animated: Bool) {
       super.viewWillAppear(animated)
       self.preferredContentSize = self.view.systemLayoutSizeFitting(
           UIView.layoutFittingCompressedSize
       )
   }
   

2. Ensure that you have constraints from your popover view to the controller's root view. These can be low priority, space >= 0 constraints.
