## Discussion

Discussion For example, the following view would display a button with a ‘x’ symbol in the toolbar. struct NewContactSheet: View {     var body: some View {         NavigationStack {             NewContactEditor()                 .toolbar {                     Button(role: .cancel) {                         dismissView()                     }                 }         }     } }
