I’ve made this using my interpretation of your idea.
Feel free to change the code to your liking and add your own data model.
This is just something you can use as a sort of template for what you are trying to achieve.

Code Block Swiftstruct ContentView: View {
	var body: some View {
		List {
			ForEach(data, id: \.title) { item in
				// to have a toggle
				Toggle(isOn: $item.isChecked) {
					Text(item.title)
				}
				// to have a checkbox
				Button {
					item.isChecked.toggle()
				} label: {
					Label(item.title, systemImage: item.isChecked ? "checkbox.square" : "square")
				}
			}
			Button("Logout") {
				// logout
			}
			.disabled(data.allSatisfy { !$0.isChecked })
		}
	}
}
