In Xcode beta 13, the documentation of NSPersistentContainer.loadPersistentStores(completionHandler:) goes like:
You can call this method from synchronous code using a completion handler, as shown on this page, or you can call it as an asynchronous method that has the following declaration: func loadPersistentStores() async throws -> NSPersistentStoreDescription
However I couldn't call it like that as it complains about a Missing argument for parameter 'completionHandler' in call. E.g.:
do {
try await container.loadPersistentStores()
} catch {
// Handle error
}
Was it intentionally left aside? Perhaps it is to be added in future Xcode 13 versions?
