Adaptive Layout doesn't work with compositional layout of collection view

Description

When working with FloatingPanelAdaptiveLayoutAnchor, regular UICollectionViewFlowLayout works fine, but compositional layout shows nothing. Can someone let me know what kind of a mistake I am doing here? Maybe it is something on my end.

To adapt to the compositional layout height

Nothing is shown

Thank you for your sample code. I'll try to investigate this issue later.

I confirm collectionView(_:cellForItemAt indexPath:) delegate method isn't called if the collection view uses a compositional layout. I keep investigating why it happens.

Finally, I've fixed this issue. As a temporary workaround, you can add a heightAnchor to the collection view to resolve the issue.

-            collectionView.trailingAnchor.constraint(equalTo: view.trailingAnchor)
+            collectionView.trailingAnchor.constraint(equalTo: view.trailingAnchor),
+            collectionView.heightAnchor.constraint(greaterThanOrEqualToConstant: 1.0),
