title: Executing a terminal command during UI test
body: <p>While running a UI test in Xcode 8, I would like to run a command (such as ssh into a server) using the NSTask/Process class to verify that the server processed the UI command successfully. However, I get the following error when trying to use the Process/NSTask class:</p>
  
  <p>'Use of unresolved identifier 'Process' (Same error when trying to use NSTask). </p>
  
  <p>Is there any workaround to this? Thank you!</p>
