I’m working on an app where I have some sensitive data that I want to encrypt when persisting. It looks like SwiftData has a BackingData protocol but it mentions it's for in-memory only. Is there a way to provide a custom storage for SwiftData so that I can encrypt the data before saving?

I have Xcode 26 on one Mac, but LM Studio running on another. LM Studio does not have an api key so I have provided "dummy-api-key" but whenever I try to connect, it gives the error "Models could not be fetched with the provided account details" I have the IP and port (1234) of LM Study The server in LM Studio is running. Has anyone got this to work? And if so, what details did you enter?
