title: ios newly created swift file import cocoa defaultly in xcode
body: <p>I'm developing an iOS app and want to build new features in swift now. But when I create a new file by Xcode->File->New->File->Cocoa Class->Language Swift  the newly created file always <code>import Cocoa</code> instead of <code>UIKit</code>.</p>
  
  <p>Is this the default behavior for all of you? And is there a way to change to import UIKit every time create a new swift file?</p>
  
  <p>UPDATE: thanks for all the answers. I made a terrible mistake</p>
