I decided it would be more appropriate to provide an explanation than to send in a sample project.
I used addSubview some views inherited UICollectionViewCell to a view that was not UICollectionView.
UICollectionViewCell was used as the parent view in order to use views of various structures while maintaining SSOT in UIStackView (or autolayout) and UICollectionView.
As a result, changes calling invalidateIntrinsicContentSize() in UICollectionViewCell in iOS 16 affected my structures
It works after iOS 15.0 developer beta 5 with Safari Technology Preview. :)
and also you can use inspector on Simulator on Xcode 13.0 beta latest version
You could use Safari Web Inspector on iOS 14.7 beta 2.
But it didn’t work on iOS 15.0 developer beta yet..
