I got the "Picker: the selection "" is invalid and does not have an associated tag, this will give undefined results" warning in the console when I run the application and navigated to the AddBookView.

@State private var rating = 3

Section {
    TextEditor(text: $review)
    Picker("Rating", selection: $rating) {
        ForEach(0..<6) { rating in
            Text("\(rating)")
        }
    }
} header: {
    Text("Write a review")
}

There was no warning when Paul navigated to AddBookView. Why do I get this warning?

Add id: \.self to ForEach should make the warning go away.

ForEach(0..<6, id: \.self) { rating in
    Text("\(rating)")
}

Unfortunately it still appears.

Thank you! I completely forgot that second picker.
