I am trying to count a database table from inside some of my classes. I am tying to do this below **(My problem is that count1 is working, but count2 is not working.) **
class AppState{
private(set) var context: ModelContext?
....
func setModelContext(_ context: ModelContext) {
self.context = context
}
@MainActor
func count()async{
let container1 = try ModelContainer(for: Item.self)
let descriptor = FetchDescriptor<Item>()
let count1 = try container1.mainContext.fetchCount(descriptor)
let count2 = try context.fetchCount(descriptor)
print("WORKING COUNT: \(count1)")
print("NOTWORKING COUNT: \(count2) -> always 0")
}
I am passing the context like:
...
@main
@MainActor
struct myApp: App {
@State private var appState = AppState()
@Environment(\.modelContext) private var modelContext
WindowGroup {
ItemView(appState: appState)
.task {
appState.setModelContext(modelContext)
}
}
.windowStyle(.plain)
.windowResizability(.contentSize)
.modelContainer(for: [Item.self, Category.self]) { result in
...
}
Can I get some guidance on why this is happening?
Which one is better to use?
If I should use count2, how can I fix it?
Is this the correct way to search inside an application using SwiftData ?
I don't wanna search using the View like @Query because this operation is gonna happen on the background of the app.
