I suggest you to use stable version of Xcode 6.1.1.

FBSOpenApplicationErrorDomain, code =4 error suggests it is an error from 
cached data on the simulator.

There are three possible solutions :

  1. Clean simulator. Use (Command + Shift + k) as shortcut key or goto Product -> Clean

  2. Quit simulator and relaunch it.

  3. Open simulator. Select iOS simulator -> Reset contents and settings...

Option 3 worked for me.
