title: Use iOS 10.3.3 with Xcode Version 8.2.1?
body: <p>I am using Xcode Version 8.2.1 and cannot upgrade because I am working off of a 2008 MBP and the latest versions of Xcode are not supported.</p>
  
  <p>I trying to run a project on an iPhone 5 which is running iOS 10.3.3 however, when i try to run the project from Xcode I get the following error message:</p>
  
  <p><a href="https://i.stack.imgur.com/Ru2Cr.png" rel="noreferrer"><img src="https://i.stack.imgur.com/Ru2Cr.png" alt="error message"></a></p>
  
  <p>I checked the device support folder located at:
  /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/</p>
  
  <p>and I see that the 10.3 folder is not present</p>
  
  <p><a href="https://i.stack.imgur.com/cHaQ5.png" rel="noreferrer"><img src="https://i.stack.imgur.com/cHaQ5.png" alt="device support"></a></p>
  
  <p>Is there a way I can add a folder for 10.3 device support? Is there a place I can download it and add it into my Xcode?</p>
  
  <p>If this is not possible, does anyone know a way to downgrade to an unsigned iOS firmware such as 10.2 or lower?</p>
