I'm following the guide Migrating to the App Asset Library to replace the deprecated app screenshot and preview API with the new app asset library API.
Only it seems that the documentation for this new API is already outdated. Specifically, when creating new placements, I get a AppAssetLibraryPlacementsResponse where the state can be ACTIVE, PENDING or INVALID, but the documentation for AppAssetLibraryPlacementState doesn't mention any of these values.
For reference, I'm using appstoreconnect-swift-sdk which creates Swift code from the API specification.
