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
