Using SwiftUI, how do I make one Toggle change the state of another Toggle?
Since I don't know hte challenges of your design, I won't go into wether it is the right approach or not (unless that is your question). However, to achieve what you asked for, you can use an intermediary binding:
struct Junk: View { @State private var isOn1:Bool = true @State private var isOn2:Bool = false @State private var isOn3:Bool = false var body: some View { let on1 = Binding<Bool>(get: { self.isOn1 }, set: { self.isOn1 = $0; self.isOn2 = false; self.isOn3 = false }) let on2 = Binding<Bool>(get: { self.isOn2 }, set: { self.isOn1 = false; self.isOn2 = $0; self.isOn3 = false }) let on3 = Binding<Bool>(get: { self.isOn3 }, set: { self.isOn1 = false; self.isOn2 = false; self.isOn3 = $0 }) return VStack { Toggle("T1", isOn: on1) Toggle("T2", isOn: on2) Toggle("T3", isOn: on3) } }}
