Answer 1

it is state of your app at the crash moment, can show you where crash was. In your case app crashed with Exception Type: EXC_CRASH (SIGKILL) in thread 0 and you can see stacks of functions of all active threads. If you want convert it to human readable view, you should use special programs like symbolicate , atos or dwarfdump.

Answer 2

It is very simple if you have the archive file in Xcode -> Widow ->Organizer and a corresponding crash log file.

Connect your device to mac

goto Xcode->Window-> devices

Click on your device on the left panel

Click on view device logs

Select the log you want to symbolicate. (OR) If you have a crash log file on your system then click on All logs option on the left panel and drag the log file into left panel section.

Right click on the selected log and click re-symbolicate

Done!!! ,
