title: connect to sFTP server while using Xcode
body: <p>I wonder how to access scripts on a sFTP server when using Xcode.
  I want to write the code using Xcode and update it on the server simultaneously every time I save the code. 
  There is similar function in TextWrangular, where you can "open from sFTP/FTP server".
  I try to add server in Xcode, I choose Preferences->Accounts-> Add Server, but when I enter the server address and my user name, it says could not connect to the server. I wonder if this is possible using Xcode or what I've done wrong!</p>
  
  <p>Thank you very much!!! </p>
