    You can check what the exception is with a simple lldb command, once the debugger stops on the exception. Select the exception like in your thread 6 here:

    enter image description here

    And then if you are running on the simulator type:

    po $eax
    

    If you are running on the device:

    po $r0  (for 32-bit)
    po $x0  (for 64-bit)
    

    You should get a description of the exception.
