<p>Here is an updated example that would work:</p>
<pre><code class="swift">let (first, second: (x, y)): (first: Int, second: (x: Int, y: Int)) = tuple
</code></pre>
<p>This should work right? It’s assigning the inner tuple to <code>second</code> while also creating two additional constants from the inner tuple. I know this is redundant and can be used as <code>second.x</code>, but this should work like right, because it’s nested tuple destructuring? If we’d use <code>var</code> instead of <code>let</code> then <code>x</code> would contain the value assigned from the inner tuple, but it would be completely independent from the new <code>second</code> tuple variable.</p>
