The following works without issue.

struct ContentView: View {
    enum ModelCategory: String, CaseIterable, Identifiable {
        case one, two, three, four, five, six

        var id: String {
            self.rawValue
        }
    }

    var body: some View {
        VStack {
            ForEach(ModelCategory.allCases, id: \.self) { value in
                Text(value.id)
            }
        }
    }
}

But because you have introduced a member variable that is not initialized this is the error being raised. If you have a preview snippet, pass the showBrowse param into the ModelsByCategoryGrid(showBrowse: Binding.constant(false)) or give the showBrowse a default value.

    @Binding var showBrowse: Bool
