I've used this approach and it works well: https://schwiftyui.com/swiftui/playing-videos-on-a-loop-in-swiftui/
You can use a Swift Package to get SwiftUI support for SWAttributionView. It is referenced towards the bottom of this article: https://www.avanderlee.com/swift/shared-with-you/
Do I need to implement SWCollaborationMetadata for Shared With You to work? I have the universal link set up and all the items you list above but my highlightCenterHighlightsDidChange delegate method is not getting called with content that appears in Messages that has a universal link that does open my app but nothing shows in my Shared With You shelf.
For the same app, I get this error running on a iOS 14.8 device but I do NOT get the error on a 15.3.1 device.
Try turning off your compass in Settings or move your device away from other electronics.
