I believe most of us just want debugging to be usable. It is usable over usb, but it isn't over wifi. Simple as that. Nothing to do with VPN's.
Testing my most recent app, with wifi enabled it takes 57 seconds from reaching a breakpoint to finishing loading variables. Same operation with wifi disabled takes less than 2 seconds.
Ideally I would like to connect to my device over wifi without this enormous time penalty. If that's not possible, I would like to be able to set usb as my default connection without having to use the workarounds above. Unreasonable?

After much time and effort I may be able to provide a clue for some people. My simple test app displays a List of parents - you select a parent, and a second List displays it's children. My first attempt worked fine - when I deleted a parent, it's children were cascade deleted (I checked the sqlite3 database to be sure).
Next I tried to programatically select a parent. Now, when I delete that parent, it's children are deleted in my app, but they continue to exist as orphans in the database.
Maybe someone brighter than me can figure out why...

@main
struct Trial_SwiftDatabaseApp: App {
var sharedModelContainer: ModelContainer = {
let schema = Schema([FirstLevel.self, SecondLevel.self])
let modelConfiguration = ModelConfiguration(schema: schema, isStoredInMemoryOnly: false)
do {
return try ModelContainer(for: schema, configurations: [modelConfiguration])
} catch {
fatalError("Could not create ModelContainer: \(error)")
}
}()
var body: some Scene {
WindowGroup {
ContentView()

.modelContainer(sharedModelContainer)

@Relationship(deleteRule: .cascade, inverse: \SecondLevel.my1st) var my2nds: [SecondLevel]

self.name = name
self.my2nds = my2nds

Having the same problem. I enter data on my MacBook Pro and I see records updated on the CloudKit console. My iPhone app sees the updates, no problem. But my iMac doesn’t.
Conversely, records updated on my iMac remain in local storage.
