Get all key paths from a struct in Swift 4 : <p>Let's say I have that struct:</p>

<pre><code>struct MyStruct {
    let x: Bool
    let y: Bool
}
</code></pre>

<p>In Swift 4 we can now access it's properties with the <code>myStruct[keyPath: \MyStruct.x]</code> interface.</p>

<p>What I need is a way to access all it's key paths, something like:</p>

<pre><code>extension MyStruct {

    static func getAllKeyPaths() -&gt; [WritableKeyPath&lt;MyStruct, Bool&gt;] {
        return [
            \MyStruct.x,
            \MyStruct.y
        ]
    }

}
</code></pre>

<p>But, obviously, without me having to manually declare every property in an array.</p>

<p>How can I achieve that?</p>
