Is there any change in Swift, so this:

guard let thisDataSource = tableView.dataSource as? Self<SectionIdentifierType, ItemIdentifierType, EquatableCellContent>, let cell = cellProvider(tableView, indexPath, itemIdentifier) else { return nil }

cannot be compiled in the XCode 13 beta 5? This works with XCode 12, but the XCode 13 beta 5 does not compile, and says: Error: Cannot specialize Self

(I have created feedback about this too, but my experience with resolving feedbacks is not the best...)

The code is the example example in https://github.com/hibernat/DiffableWithReload

Resolved. Xcode 12 does not compile correctly.

Instead of Self<SectionIdentifierType, ItemIdentifierType, EquatableCellContent> is enough just Self. Works in Xcode 13.

Thanks, Apple!
