# Understanding the exception types in a crash report

Learn what the exception type tells you about why your app crashed.

## Overview

Overview The exception type in a crash report describes how the app terminated. It’s a key piece of information that guides how to investigate the source of the problem. Exception Type: EXC_BAD_ACCESS (SIGSEGV) Crash reports record language exception information separately, including language exceptions thrown by an API or language features in Objective-C or C++.
