Swift CollectionView et TableView dans ScrollView

Donc, comme vous pouvez le voir sur la photo ci-dessous, j'ai collectionView et TableView dans ScrollView. Et cela ne fonctionne pas comme je m'y attendais. Vous pouvez voir le problème dans l'image gif. Le CollectionView a une hauteur statique = 100 et tableview a une hauteur auto-dimensionnée. La hauteur et la largeur de StackView sont égales à la hauteur et à la largeur de ScrollView. On dirait qu'il y a quelque part une petite erreur, mais je ne peux pas le découvrir.

ici AutoSizeClass pour TableView:

class AutoSizingTableView: UITableView {
    
      override var intrinsicContentSize: CGSize {
          self.layoutIfNeeded()
          return CGSize(width: UIView.noIntrinsicMetric, height: contentSize.height)
      }
      
      override var contentSize: CGSize {
          didSet{
              self.invalidateIntrinsicContentSize()
          }
      }
      
      override func reloadData() {
          super.reloadData()
          self.invalidateIntrinsicContentSize()
      }
    
  }

Le problème est que View with Collection View reste au même endroit et ne défile pas vers le haut.

Sur la base de votre commentaire "avec le défilement désactivé dans le tableau, il ne peut pas du tout défiler" ... vous avez fait quelque chose de mal avec votre configuration.

Voici comment il doit être présenté dans Storyboard pour qu'il fonctionne. Notez que la vue tableau doit avoir le défilement désactivé :
