Solution to eliminate boilerplate code when Implementing Equatable for Associated Value Enums

gistfile1.swift

import UIKit

protocol AutoEquatableEnum {
    static func == (lhs: Self, rhs: Self) -> Bool
}

extension AutoEquatableEnum {
    static func == (lhs: Self, rhs: Self) -> Bool {
        return lhs.data == rhs.data
    }
    
    private var data: NSData {
        var copy = self
        return withUnsafePointer(to: &copy, { NSData(bytes: $0, length: MemoryLayout<Self>.size) })
    }
}

enum Test: AutoEquatableEnum {
    case foo(String)
    case bar(String)
}

Test.foo("bar") == Test.foo("bar") // true
Test.foo("bar") == Test.bar("bar") // false
Test.bar("foo") == Test.bar("foo") // true
Test.bar("foo") == Test.bar("") // false
