title: Unable to run app in Simulator: An error was encountered while running (Domain = LaunchServicesError, Code = 0)
body: <p>After successfully compiling the project in Xcode 6, I am unable to run it in the simulator with the above mentioned message. I did all the possible research, tried everything and still no advances.</p>
  
  <p>I am not working with swift, neither I use widgets or extensions, so please do not suggest solutions caused by these as can be seen in similar questions.</p>
  
  <p>If someone found a possible cause (or solution!!) other than <a href="https://stackoverflow.com/questions/25130558/unable-to-run-app-in-simulator-an-error-was-encountered-while-running-domain">these</a>, please help. Thanks</p>
