title: How to create app file with fastlane for simulator
body: <p>I need to create with fastlane .app file (or .ipa file if it works to) which I could next drag and drop to simulator on another computer. I tried do it with gym or with xcodebuild parameters but I don't know how to do it.</p>
  
  <p>For now I do it in this way:</p>
  
  <ul>
  <li><p>In XCode I build application for simulator</p></li>
  <li><p>Next I am searching app file in DerivedData (~/Library/Developer/XCode/DerivedData/Build/Products/Debug-iphonesimulator/)</p></li>
  <li><p>I copy this file somewhere else</p></li>
  </ul>
  
  <p>But I need do it with fastlane.</p>
