You can use something like the code below. Note that you will get a deprecated warning, but to address that, check this other answer: https://stackoverflow.com/a/57333200/7786555

import SwiftUIstruct ContentView: View {    @State private var boolArr = [false, false, true, true, false]    var body: some View {        List {            ForEach(boolArr.indices) { idx in                Toggle(isOn: self.$boolArr[idx]) {                    Text("boolVar = \(self.boolArr[idx] ? "ON":"OFF")")                }            }        }    }}

⛔️ Don't use a Bad practice!

Most of the answers (including the @kontiki accepted answer) method cause the engine to rerender the entire UI on each change and Apple mentioned this as a bad practice at wwdc2021 (around time 7:40)

✅ Swift 5.5

From this version of swift, you can use binding array elements directly by passing in the bindable item like:

_{⚠️ Note that Swift 5.5 is not supported on iOS 14 and below but at least check for the os version and don't continue the bad practice!}

In SwiftUI, just use Identifiable structs instead of Bools

struct ContentView: View {    @State private var boolArr = [BoolSelect(isSelected: true), BoolSelect(isSelected: false), BoolSelect(isSelected: true)]    var body: some View {        List {            ForEach(boolArr.indices) { index in                Toggle(isOn: self.$boolArr[index].isSelected) {                    Text(self.boolArr[index].isSelected ? "ON":"OFF")                }            }        }    }}struct BoolSelect: Identifiable {    var id = UUID()    var isSelected: Bool}
