Are there any crash logs generated by iPhone Simulator?

the Simulator crashes a lot but not leaving any traces in Console... the crash log will be useful.

The console will show the NSLog() output from an app running in the simulator. The crash logs are saved to file.

I have found some in my home directory under

~/Library/Logs/DiagnosticReports/

They have a file extension of .crash

Something I haven't yet figured out is how to get them to generate even if the debugger grabs the EXC_BAD_ACCESS signal.

Update

Currently, (OSX 10.11.6), the .crash logs in ~/Library/Logs/DiagnosticReports, are when the emulator itself crashes. Logs for an app crashing (but the emulator device is still running fine), are in:

~/Library/Logs/CoreSimulator

Per crash, there is a sub-folder with a unique id. Sort by date, so that your recent crash is the first sub-folder. Inside that, start by looking at stderr.log and system.log.

Also directly under CoreSimulator, see CoreSimulator.log and Simulator.log.

This is much more reliable. In only a few steps I was able to find the source line number & method name:

  1. cd to the dir having the .app & .dSYM files
  2. run /Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gdb/gdb-arm-apple-darwin MyApp.app/MyApp
  3. set print asm-demangle on
  4. set print symbol-filename on
  5. p/a 0×00015c64 -> address got by opening the crash log in “Console” app or just double clicking the the .crash file.

None of the answers above worked on the "Big Sur" OS version. The only way to find the log was through the "Console" app (Application/Utilities/Console)
