Method #1: Google Analytics 4 (Firebase) DebugView
Prerequisites:
Your developer needs to add the command line argument in Xcode, build and share the app version with you. I recommend including this argument in all future app versions so you can test the implementation in every future release. I also suggest adding this argument to non-production versions of the app, like testing or development versions.
Command line argument:
On this link is step-by-step guidance for developer how to setup command line argument.
Once the argument is implemented, app published, you can download the app and follow the steps.
Steps:
Open Google Analytics 4 DebugViewOpen iOS mobile app and generate some hits - such as screen_view or try to tap on several elements.Hurray! You can see hits in GA4 debugView
Tip:
Some developers include a special menu in the development version of their app. You could ask them to add a switch that controls the argument values, allowing you to easily turn the debugView on or off as needed.
