How to use array of strings in ForEach in SwiftUI

Issue #483

Every item in list must be uniquely identifiable

List {
    ForEach(books, id: \.bookId) { book in
        NavigationLink(destination:
            BookView(book: book)
                .navigationBarTitle(book.name)
        ) {
            VStack {
                Text(book.name)
            }
        }
    }
}

In case of primitive, we can just provide id to conform to Identifiable

extension String: Identifiable {
    public var id: String {
        return self
    }
}
