XCode Beta 7 - Cannot convert value of type 'ModelConfiguration' to expected argument type 'any PersistentModel.Type'

I had to explicitly put in function parameter for ModelContainer.

So change:

 .modelContainer(try! ModelContainer(for: Closet.self,
                                                    config))

to:

 .modelContainer(try! ModelContainer(for: Closet.self,
                                                    configurations: config))

The signatures for the ModelContainer convenience initializers have changed to take the configuration as a named parameter. This should do the trick:

struct AppleClosetApp: App {
    let config = ModelConfiguration(url: AppGroup.facts.containerURL ?? URL(fileURLWithPath: ""))
    
    var body: some Scene {
        WindowGroup {
            ClosetNavigationView()
                .modelContainer(try! ModelContainer(for: Closet.self,
                                                    configurations: config))
        }
    }
}
