How to change height of UIView that already has height anchor?

Question

If I have this for a child view controller:

autoCompleteViewController.view.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.act         


        

Answer 1

I've fixed it by implementing it like this:

autoCompleteViewControllerHeight = NSLayoutConstraint( item: autoCompleteViewController.view, attribute: .height, relatedBy: .equal, toItem: nil, attribute: .height, multiplier: 1.0, constant: 44.0) guard let autoCompleteViewControllerHeight = autoCompleteViewControllerHeight else { return } autoCompleteViewControllerHeight.isActive = true

and then where it should be changed I added:

let newHeight = calculateNewHeight() heightConstraintAutoCompleteViewController.constant = newHeight

It works like a charm.
