Hi! I have a CollectionView with Drag and Drop and Context Menu functionality. There's a memory leak caused by returned [UIDragItem] array in ItemsForBeginning method when I initialise cell's context menu. Objects are being kept in memory when I pop to rootViewController. All is OK though when drag session was happened. I've ended up commenting out everything, keeping blank UIDragItem and problem is still there:     func collectionView(_ collectionView: UICollectionView, itemsForBeginning session: UIDragSession, at indexPath: IndexPath) - [UIDragItem] {         let dragItem = UIDragItem(itemProvider: NSItemProvider(object: "" as NSString))         return [dragItem]     } Does anybody experience this? Looks like it's a UIKit bug... Please help!
