Failed to build active scheme

My SwiftUI project won't build anymore. It tells me Failed to build active scheme without any more information.

Here's the full repository: https://github.com/nathfreder/HackerNews/tree/master/HackerNews

I noticed the issue after changing

ForEach(0..<10) { _ in
    NavigationButton(destination: Text("")) {
        StoryRow()
    }
}

to

ForEach(store.stories) { story in
    NavigationButton(destination: Text("")) {
        StoryRow(story: story)
    }
}
