Description
After updating to Swift 6 with complete concurrency checking following Migrate your app to Swift 6, I am getting multiple warnings. One on a List looks like so:
Static property 'v17' is not concurrency-safe because non-'Sendable' type 'PlatformViewVersion<iOSVersion, ListType, UICollectionView>' may have shared mutable state; this is an error in the Swift 6 language mode

As an intermediate workaround, I think you can put this somewhere in your top level code. However, not sure if it´s correct.
extension iOSViewVersion<ScrollViewType, UIScrollView> {
nonisolated(unsafe) public static let v17 = Self(for: .v17)
}
