    var body: some View {
        VStack {

        }
    }
}

Signal.swift

import Foundation

}

extension Signal: Equatable {
    static func ==(lhs: Signal, rhs: Signal) -> Bool {
        return lhs.id == rhs.id
    }

SignalStore.swift

import SwiftUI

    var all = [Signal]()

    func binded(signal: Signal) -> Binding<Signal> {
        Binding(
            get: { self.all[self.all.firstIndex(of: signal)!] },
            set: { self.all[self.all.firstIndex(of: signal)!] = $0 }
        )

    @Binding var signal: Signal

    var body: some View {
        Text("...")
    }
}
