The Debug Symbol file and application binary are tied together on a per-build-basis by the build UUID. By default, debug builds of an application store the debug symbols inside the compiled binary while release builds of an application store the debug symbols in a companion dSYM file to reduce the binary size. Depending on the Debug Information Format ( DEBUG_INFORMATION_FORMAT) build setting, these debug symbols are stored inside the binary or in a companion Debug Symbol ( dSYM) file. ![]() This section focuses on symbolicating crash reports from iOS, watchOS, and tvOS, but the overall process is similar for macOS.Īs the compiler translates your source code into machine code, it also generates debug symbols which map each machine instruction in the compiled binary back to the line of source code from which it originated. Note: Crash reports from macOS are typically symbolicated, or partially symbolicated, at the time they are generated. Note: Low Memory Reports do not need to be symbolicated. Without first symbolicating a crash report it is difficult to determine where the crash occurred. Symbolication is the process of resolving backtrace addresses to source code method or function names, known as symbols. Acquiring Crash and Low Memory Reportsĭebugging Deployed iOS Apps discusses how to retrieve crash and low memory reports directly from an iOS device.Īnalyzing Crash Reports in the App Distribution Guide discusses how to view aggregate crash reports collected from TestFlight beta testers and users who have downloaded your app from the App Store. This document points to you several memory management references that you might find useful. When a low memory crash happens, you must investigate your memory usage patterns and your responses to low memory warnings. See Symbolicating Crash Reports for details.Ī Low Memory report differs from other crash reports in that there are no backtraces in this type of report. ![]() ![]() crash file yourself by importing it to the Xcode Devices window. Otherwise you will need to symbolicate the. If you get crash logs off a device through Xcode's Devices window, then they will be symbolicated for you automatically after a few seconds. Symbolication replaces memory addresses with human-readable function names and line numbers. You should look at these crash reports to understand what crashes your application is having, and then try to fix them.Ĭrash reports with backtraces need to be symbolicated before they can be analyzed. Crash reports describe the conditions under which the application terminated, in most cases including a complete backtrace for each executing thread, and are typically very useful for debugging issues in the application. When an application crashes, a crash report is created and stored on the device. ![]()
