I'm using the latest version of the Google/Analytics pod and it keeps showing the following message in the console and it's driving me nuts:
<Error> [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add [FIRApp configure] to your application initialization.
I don't want to install Firebase right now. I need to report to two GA suites and also can't implement GTM yet. I did try installing Firebase to get rid of the messages. However, it required me to use the Google plist file and set a tracking ID in there (I was manually configuring my trackers instead) which then caused the app to be unable to report to both GA suites and it reported double to the one suite referenced in the plist file. I've also tried using the other pod - GoogleAnalytics and that didn't solve any problems.
Ultimately, I just want to not have Google bug me with the incessant messages in the console. Any solutions?
UPDATE: I must not have cleared my console or something when I made the switch to use the GoogleAnalytics
pod instead. I just tried that again and it seems to have done the trick in getting rid of Firebase nagging me for configuration.
UPDATE 2: Just found this question which has basically my same answer: https://stackoverflow.com/a/41511545/284630
