I uploaded a version of my app – this error pop ups and I dont have any changes from the Google Maps portion of my app. On my first upload, there was no problem.
This issue is probably Apple's iTunesConnect side of the problem. see my question: ITMS-90451:CFBundleIdentifier Collision Error
I also encountered the same problem in the submission of the application using the Qt framework. I have submitted a report in https://bugreport.apple.com/. Something I will even write if there is a reply from Apple.
This issue is either iTunesConnect issue or Cocoapods.
When you archive and submit the App, you get this “CFBundleIdentifier Collision Error” because iTunesConnect is considering info.plist of one of pod dependency not your Watchkit App or its parent App.
In our case, it was considering Google Maps and Instabug's info.plist file.
Solution : To solve this issue we deleted all the values of info.plist from our pod dependency. Clean archive and successfully submitted.
GoogleMap iOS SDK contains info.plist on following path : GoogleMapSDK -> Resources -> GoogleMaps.bundle -> info.plist
