Typically, NullReferenceExceptions happen inside the Start method when incorrect assumptions are made about initialization order. Looking carefully at this method implementation would reveal the cause of the problem. In this example, the trace indicates that the NullReferenceException happened inside the OptionsMenu script’s Start method. The very first lines of the stack trace will point to the place where the error occurred.

Carefully inspect the printed stack traces they may contain hints about where the error occurred. To get a native stack trace, type bt all into the Xcode Debugger Console. Also, you generally can’t continue after these native (hardware memory access) faults happen. Native stack traces are a much more powerful tool for fault investigation but using them requires some expertise. Use Native stack traces to find out where the fault occurred: Native stack traces This message typically appears on iOS devices when your application receives a NullReferenceException. The Xcode console shows "Program received signal: “SIGBUS” or EXC_BAD_ACCESS error. Information from the XCode Debugger console can often help detect these problems (Xcode menu: View > Debug Area > Activate Console).
