title: swift properties empty setters and getters
body: <p>I'm a beginner in Ios development so please forgive me if this sounds like a silly question. I often see properties declaration like this:</p>
  
  <pre><code>var desiredAccuracy: CLLocationAccuracy { get set }
  </code></pre>
  
  <p>so what does <code>{ get set }</code> mean? Is it an empty getter and setter for a variable?</p>
