title: Reset iPhone simulators to default?
body: <p>I've somehow collected a long list of iPhone simulators in Xcode:</p>
  
  <p><a href="https://i.stack.imgur.com/uW5dG.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uW5dG.png" alt="list"></a></p>
  
  <p>I'd like to clear this, and restore a simulator for each device model and each installed simulator version, i.e.:</p>
  
  <ul>
  <li>iPhone 4S (iOS 8.3)</li>
  <li>iPhone 4S (iOS 8.4)</li>
  <li>iPhone 4S (iOS 9.0)</li>
  <li>iPhone 5 (iOS 8.3)</li>
  <li>iPhone 5 (iOS 8.4)</li>
  <li>iPhone 5 (iOS 9.0)</li>
  </ul>
  
  <p>...etc.</p>
  
  <p>How can I do this in an automatic manner? I don't care about losing any data on current simulators.</p>
  
  <p>This question is distinct from the <a href="https://stackoverflow.com/questions/31285059/xcode-6-4-showing-duplicate-simulators-with-unique-id">reported duplicate</a>, because it requires that the simulators be <em>recreated</em>, as a clean install of Xcode does. The other question's answers merely <em>delete</em> the simulators.</p>
  
  <p>It also requires that the deletion and creation be <em>automated</em>, i.e. "click the delete button a bunch of times, then click the add button a bunch of times" is not the answer.</p>
