Wait for config files to load in SwiftUI App

Question

I have an app that is pure SwiftUI. I am trying to stick to dependency injection for my Home view and its associated ViewModel.

In that spirit, there are some elements of a config file which are a dependency of my Home views associated ViewModel. Mainly, the current list of words for the speech recognition service to look for.

I would love to call my config remotely with a very short timeout (less than two seconds) and provide a local copy in the event of timeout.

For example:

struct MyApp: App {

    var words: SpeechDictionary
    var viewModel: HomeViewModel
    
    init() {
        words = SpeechDictionary()
        //Any blocking function, await used as illustration
        await words.update()
        
        viewModel = HomeViewModel(dictionary: words)
    }
    
    var body: some Scene {
        WindowGroup {
            HomeView(viewModel: viewModel)
        }
    }
}

If I don't await the calls here, I have to add state flags, subscribers, and hope the user doesn't try to use the app before the home screen loads (or lock them out with a second spinner). This all seems very un-swifty and not following SOLID patterns.

What's the cleanest way to handle the above situation?
