int(numbers.dropFirst())
// Prints &quot;[2, 3, 4, 5]&quot;</code></pre>

<p>If the sequence has no elements, the result is an empty subsequence.</p>

<pre><code class="language-swift">let empty: [Int] = []
print(empty.dropFirst())
// Prints &quot;[]&quot;</code></pre>

<p><strong>Returns:</strong> A subsequence starting after the first element of the
  sequence.</p>

<p><strong>Complexity:</strong> O(1)</p>
