Simplifies binding option set values to a SwiftUI View.

Binding+OptionSet.swift

import SwiftUI

public extension Binding where Value: OptionSet {
    func toggling(_ value: Value.Element) -> Binding<Bool> {
        .init(
            get: {
                wrappedValue.contains(value)
            },
            set: {
                if $0 {
                    wrappedValue.insert(value)
                } else {
                    wrappedValue.remove(value)
                }
            }
        )
    }
}

Example:

struct ContentView: View {
    @State private var edges: Edge.Set = []
    
    var body: some View {
        Toggle("", isOn: $edges.toggling(.bottom))
    }
}

Toggling the control, will insert/remove the .bottom value from the option set. Can be used with any OptionSet.
