Hi everyone! Is this a feature yet? Here is my use case... I have an iOS app using CloudKit for the backend. I have a record for custom user called MyUser. Each MyUser record has a field called username. I want to let the users edit their usernames on the app but I also want to make sure there are no duplicate usernames. If a user tries to change their username to a username that is already taken I want them to see an error. If I could mark the username field as must be unique on CloudKit, then when I send the network request to change the username CloudKit will send an error back if it is taken. Without this, I can implement my own check to see if a username is taken by querying the MyUser records by username. But what if two different apps query for the same username at the same time... yes there is only a very small chance of this happening but it is NOT impossible. The queries would return with no users ( aka username is available ) and then both users would send the next network request to change their usernames to the same username. Is there a better way to achieve this? I think marking the username field on the MyUser record as "isUnique" would be very handy.

navigationDestination is still very buggy on 17.3. it doesn't register the first change to the NavigationStack(path:) binding...

Thank you! This is what I was looking for.

Thank you so much for the reply! that worked.
