I don't have an answer for ye. However, this clue might help?

In January 2024, Stewart Lynch completed a series of YouTube vids on SwiftData.

In his first episode titled SwiftData CRUD Operations Stewart writes a line of code to reveal the location of the SwiftData files. In subsequent lessons he navigates to this folder to make backups whilst testing delete and other functions.

Keep Coding

Please return here and let us know how you implemented this in your application!

Thanks. The video helped me. With these code snippets you can display the location and the existing files. The idea now is to share these files so that you have a backup of the database.

        print(URL.applicationSupportDirectory.path(percentEncoded: false))
        let directoryPath = URL.applicationSupportDirectory.path(percentEncoded: false)
        let fileManager = FileManager.default
        do {
            let fileURLs = try fileManager.contentsOfDirectory(at: URL(fileURLWithPath: directoryPath), includingPropertiesForKeys: nil)

            for fileURL in fileURLs {
                print("\(fileURL.lastPathComponent)")
            }
        } catch {
            print("Cant read Files \(directoryPath): \(error.localizedDescription)")
        }

default.store
default.store-wal
default.store-shm

This works for the ios device simulator, but it is not obvious to me how to backup files on a real ios device in view of sandboxing.

To back up the SwiftData database from your iPhone app, connect your iPhone to your computer and use software like iTunes, iExplorer, or iMazing to access its file system. Navigate to the folder where the app's data is stored, typically within the "Apps" or "App" folder. Look for the SwiftData database file, usually with a ".sqlite" or ".db" extension, and copy it to your computer.
