Update:

I made a couple of changes that seemed to have helped. The app is still crashing but less frequently. Also I added log statements to help pinpoint where and when it is crashing.

The change I made that seemed to help was increasing the value for dispatchInterval (previous set to 20)...

[GAI sharedInstance].dispatchInterval = 60;

Also, the crash only seems to occur when the app is launched and/or becomes active while trying to track an event in the app delegate method...

- (void)applicationDidBecomeActive:(UIApplication *)application {

        ...

        GA_EVENT(@"App Launch", @"", @"App Launched", 0);

        // NOTE: GA_EVENT defines a custom method that creates the event (GAIDictionaryBuilder) 

        // and invokes the GAITracker's send method with the event per usual.        

        // This approach is used throughout the app and was working fine prior 

        // to iOS 12, but is now causing a crash here for some reason

        ...

}

Lastly, in the event that this is a bug with GA SDK, I created an issue in their bug tracker. From my research, the last time this crash was reported it seemed to have required an update to their SDK. So, perhaps that's the case here as well. We'll see if I hear anything back from the Google gods...
