Running application in iOS Simulator times out without directions

1. Create a new project.
   I used a Qt Widget Application project.
2. Configure the project to use the Qt iOS Simlator.
3. Select "Build" -> "Run" from the menu.
   After 30 seconds, Creator will write the following to the Application Output view:

   Session could not be started: Error Domain=DTiPhoneSimulatorErrorDomain Code=2 "Simulator session timed out." UserInfo=0x1016c9730 {NSLocalizedDescription=Simulator session timed out.}Run ended unexpectedly.
   

   The iOS Simulator window opens up but does not show your application project. The behaviour is the same if the Simulator is already running before.

4. Wait for about ten minutes.
   Your application will start in the emulator. Now the emulator can be used.

If the emulator really is that slow, Creator should indicate this in some way, e.g. it could suggest the user to get a coffee until Apple finally gets its software sorted.
