title: Delay/Wait in a test case of Xcode UI testing
body: <p>I am trying to write a test case using the new UI Testing available in Xcode 7 beta 2. The App has a login screen where it makes a call to the server to login. There is a delay associated with this as it is an asynchronous operation.</p>
  
  <p>Is there a way to cause a delay or wait mechanism in the XCTestCase before proceeding to further steps?</p>
  
  <p>There is no proper documentation available and I went through the Header files of the classes. Was not able to find anything related to this.</p>
  
  <p>Any ideas/suggestions?</p>
