📦dismiss
SwiftUI ⟩ view ⟩ environment ⟩ value ⟩ dismiss
An action that dismisses the current presentation.
@Environment(\.dismiss) var dismiss
Use this environment value to get the DismissAction
instance for the current Environment
. Then call the instance (dismiss()
) to perform the dismissal.
You call the instance directly because it defines a callAsFunction()
method that Swift calls when you call the instance. You can use this action to:
dismiss a modal presentation, like a sheet or a popover.
pop the current view from a
NavigationStack
.
struct CreatureEditor: View {
@State var newCreature = Creature(name: "", emoji: "") // new creature to add to data
@EnvironmentObject var data : Zoo // data model
// ⭐️⭐️⭐️ allow the app to dismiss the current view
@Environment(\.dismiss) var dismiss
var body: some View {
VStack(alignment: .leading) {
Form { ... } // for editing new creature
Button("Add") {
// add new item to data
data.creatures.append(newCreature)
// ⭐️ dismiss current view
dismiss()
}
}// VStack
}
}
