On iOS 12, there are issues with self-sizing cells as described in Apple release notes (https://developer.apple.com/documentation/ios_release_notes/ios_12_release_notes) :
|
|
"You might encounter issues with systemLayoutSizeFitting(_:) when using a UICollectionViewCell subclass that requires updateConstraints().
|
|
(42138227) — Workaround: Don't call the cell's setNeedsUpdateConstraints() method unless you need to support live constraint changes.
|
|
If you need to support live constraint changes, call updateConstraintsIfNeeded() before calling systemLayoutSizeFitting(_:)."
