Compiler crash with associated types

[eito]

I've run into an issue where one of my "view models" has an associated type that itself has an associated type.

It looks like it's crashing the Swift compiler and I'm not sure if there is something I can potentially do to work around or alter my modeling to get past this.

Here is my project.
https://github.com/eito/xui-bug

Xcode 14.2

Inside the ContentView.swift I have 3 approaches for different approaches for how the view model is defined in the view/how it's used.

This approach fails to compile -- triggers the crash

struct ContentView: View {

    @Store
    var viewModel: any MainViewModelProtocol

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello, world!")
        }
        .padding()
        .sheet(item: $viewModel.otherViewModel) { viewModel in   // this is triggering the issue when the view model defined this way
            Text(viewModel.otherText)
        }
    }
}

This approach compiles, but isn't a valid solution

struct ContentView: View {

    @Store
    var viewModel: any MainViewModelProtocol

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello, world!")
        }
        .padding()
    }
}

This approach also compiles, but is also not a valid solution for me.

struct ContentView: View {

    @Store
    var viewModel = MainViewModel()

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundColor(.accentColor)
            Text("Hello, world!")
        }
        .padding()
        .sheet(item: $viewModel.otherViewModel) { viewModel in  // doesn't seem to be an issue here when not using `any Protocol`
            Text(viewModel.otherText)
        }
    }
}
