My very first iPhone development related blog posting. I've been under so many NDAs that your head would spin.

The problem to be solved is:
How do you get crash reports from users without them sending you a crash report?

I'm using the idea from Christopher Atlan for capturing crash reports on the phone. This is handy, in that it captures the data. (How I do all that is another story) The question is, how do you turn the dump of addresses into something useful? You may have heard of the sybolication utility, which requires the crash in a specific format. And you may have heard of atos which translates an address into a symbol. However,neither one really works that well with the type of crash data we have and the .dSYM file we need to map it to.

What I haven't really seen documented on the web is the use of dwarfdump to achieve that for you. Here is a sample command:

dwarfdump --lookup 0x00007855 --arch armv6 MyApp.app.dSYM/
