SwiftUI Reference

SwiftUi @State

State is almost entirely managed by SwiftUI. A State property is only meant to be accessed from inside the views body or from a function, so it is best practice to always declare state properties as private. A State value is always an instance. The view is automatically update when there is a value change.

State Toggle Example

struct ContentView : View {
@State private var name = true

var body: some View {
VStack {
if name {
Text(“Swiftly Dierkes”)
}

Toggle(isOn: $name) {
Text(“Display Name”)
} .padding()

}

}
}

Swift UI Binding

You can get a binding from a state with the binding property, or by using the $ prefix operator.
