Hello Pokpong, No, I don't use a physical keyboard, only the virtual keyboard. The version of my iPad (A16) IOS 27.0.1 The version of my App Swift Playground is 4.7

@main struct MonApp: App { var body: some Scene { WindowGroup { ContentView() .modelContainer(for: Valeur.self, inMemory: true) //Preview } .modelContainer(for: Valeur.self) //Recommended by Apple } }I just added inMemory: true after ContentView, it doesn't keep my base in preview in memory. Can you explain to me? Thank you very much.

Hello Pokpong, Thanks for the reponse, @main struct MonApp: App { var body: some Scene { WindowGroup { ContentView() .modelContainer(for: Valeur.self) } .modelContainer(for: Valeur.self) } }.modelContainer after ContentView works very well when I'm in preview .modelContainer after WindowGroup works very well when I'm in play (Recommended by Apple) I feel like I have 2 different databases, what I write in one does not appear in the other Do you think I should stay on the use recommended by Apple (after the WindowGroup) and when I want to test my application, I use the reading and not the preview. Thanks, good day
