title: Unable to find any Xcode installations thats supports at least iOS 8.0
body: <p>I haven't used my development tools for Appecelerator Titanium in a while (Studio and CLI). Now I try to run an existing app in the iOS simulator.</p>
  
  <p>From studio I can not select the iOS simulators.
  When I use the CLI and execute: appc run (platform iOS) i get this message:</p>
  
  <p>Unable to find any Xcode installations thats supports at least iOS 8.0</p>
  
  <p>I have Xcode version 9.0.1 installed. 
  <strong>How can i connect Xcode with Titanium again?</strong></p>
  
  <p>The path of the active XCode developer directory (xcode-select -p) is:
  /Applications/Xcode.app/Contents/Developer</p>
