The presence of this section in your crash report indicates that your app crashed due to an unhandled language exception. That error is thrown from code in your app itself (frame 2). The next step is for you to identify the code involved by symbolicating your crash report. For advice on this, see Adding Identifiable Symbol Names to a Crash Report.
