UICollectionViewCell content wrong size on first load

Question

I set the size of the cell using the siz

Answer 1

For those using Storyboard + AutoLayout, and choosing which constraints are active at runtime:

When using dequeueReusableCell, on first load, the cell is created but its view has not been initialised, so the constraint changes aren't saved - whatever you have set in Storyboard is used. Solution for me was to update the constraints after the view has loaded:

override func layoutSubviews() {
    super.layoutSubviews()
    adjustIconWidths()
}
