 I recently started updating an app to use the Swift 6 language mode and ran in to an issue using `AVCaptureMetadataOutputObjectsDelegate`. The issue is that the compiler cannot reason about which actor the delegate function is called on and it must be treated as nonisolated, however _we_ know that it's being called on a specific actor (in this case the `MainActor`), so how can we tell the compiler?
