title: Does Swift init(count:, repeatedValue:) work?
body: <p>Tested this from the reference: <a href="https://developer.apple.com/documentation/swift" rel="noreferrer">https://developer.apple.com/documentation/swift</a></p>
  
  <pre><code>var string = String(count: 5, repeatedValue: "a")
  // string is "aaaaa"
  </code></pre>
  
  <p>I got this error:</p>
  
  <blockquote>
    <p>Playground execution failed: error: :5:14: error: could not find an overload for 'init' that accepts the supplied arguments
    var string = String(count: 5, repeatedValue: "a")</p>
  </blockquote>
  
  <p>Does this actually work?</p>
