SwiftUI ⟩ view ⟩ state ⟩ value

The state of a view, use @State to declare and initialize a state value of a view. Also called a state property.

struct ContentView: View {

    // ⭐️ declare & initialize a state value
    @State var isOn = true
    
    // UI
    var body: some View { ... }
    
}

• SwiftUI updates your views' appearances automatically whenever your app's state changes.

• One common way to change view states is through user interaction, such as when a person taps a Button.
