Does someone have an idea how to solve this bug? does it have to do with the code? or is it just a upgrade thing to xcode 5?
thanks!

Answer 1

Reset the simulator (Menu item iOS Simulator -> Reset Content and Settings ...).
Go to the XCode Product menu, hold down Alt and click Clean Build Folder.
Go to the XCode Organiser Projects tab and delete the derived data for the project.
Finally close and restart Xcode and the simulator.
If that doesn't work, try deleting the simulator data in your application support library - the folder ~/Library/Application Support/iPhone Simulator.
There are many ways that the XCode can get itself into an inconsistent state. The above procedure should sort it out in most cases.
