** Skip to the bottom of this question to find the problem / solution **
I just finished converting my app from GA 2.0 to 3.0. Part of that conversion includes the incorporation of GAIDictionaryBuilder. The app is running but it soon crashes after launch. Here is the xcode log from start to crash. More notes at the bottom.

I get that the crash is happening because there's an unrecognized selector used with GAIDictionaryBuilder somewhere but where's the location? I am using the GAIDictionaryBuilder all over and the usage is always the same. Any suggestions for my next troubleshooting move?
[[[GAI sharedInstance] defaultTracker] send:[GAIDictionaryBuilder createEventWithCategory:@"General"
action:@"App Became Active"
label:nil
value:0]];
I needed to add build to the GAIDictionaryBuilder
[[[GAI sharedInstance] defaultTracker] send:[[GAIDictionaryBuilder createEventWithCategory:@"General"
action:@"App Became Active"
label:nil
value:0] build]];
Try adding an exceptions breakpoint first.
You can also try using some @try @catch blocks and try to catch the error (maybe catch a centralized method you use inside your code - if any).
Also, when inside your code, you can first ask yourself if the method you are trying to access by using respondsToSelector:
These are from the top of my head. I'll try to get back with updates if you provide further information.
