It appears that while ContextMenu was deprecated, .contextMenu was not, so I am using the correct option. However, there does not appear to be a way to change the color of actions at this time.

I had to add a dateAdded property and sort by that.
This is reliably how I get the issue to happen. I create 3 albums, open one of the albums to view its content (empty), go back out to the album collection view, and then if I try to add another album it crashes with that error.
I have added dateAdded to Photo and sorted by the date added, and still get the same error.
struct AlbumCollectionView: View {
@Environment(\.managedObjectContext) var managedObjectContext
@FetchRequest(entity: Photo.entity(),
sortDescriptors: [
NSSortDescriptor(keyPath: \Photo.dateAdded, ascending: true)
]
) var photos: FetchedResults<Photo>
@FetchRequest(entity: Album.entity(),
sortDescriptors: [
NSSortDescriptor(keyPath: \Album.name, ascending: true)
]
) var albums: FetchedResults<Album>

saveContext()

When trying to add that to the line, I receive Thread 1: Fatal error: Could not extract a String from KeyPath Swift.KeyPath<LockIt.Photo, Swift.Optional<Swift.String>>. I originally had just photos in the application, with that NSSortDescriptor and it seemed to work fine before. The issue was introduced when I attempted to add albums to the application.
Yes, they say to use menu instead. With a long press gesture
I'd like to make sure trackpads are supported to be a good platform citizen. Would this work for right click with a mouse on iPadOS or would I need to roll out support for that by myself?
