How to fix “Property declares an opaque return type, but has no initializer expression from which to infer an underlying type”

Paul Hudson    @twostraws   

Fully updated for Xcode 11.2

This usually happens because you accidentally created a view without filling in its contents, like this:

struct DetailView: View {
    var body: some View {

    }
}

If you created that view as a placeholder, just give it so temporary content to make the compiler happy, like this:

struct DetailView: View {
    var body: some View {
        Text("Placeholder")
    }
}
