I’ll take a look at those links. Thanks for the help! yeah that’s why I’m so lost. The error doesn’t say much. lol

This is what the error.localizedDescription prints out: The operation couldn’t be completed. (SwiftData.SwiftDataError error 1.) Chronoforge/ChronoforgeApp.swift:31: Fatal error: Could not create ModelContainer: SwiftDataError(_error: SwiftData.SwiftDataError._Error.loadIssueModelContainer, _explanation: nil) App works fine before i try to add cloudkit. After adding cloudkit it does this as soon as it launches. What are the actual general steps for adding cloudkit to a mac app? I can't seem to find any documentation for that. Just for ios.
