My app uses admob.

at Corona-3574, it crashed

*** Terminating app due to uncaught exception ‘GADInvalidInitializationException’, reason: 'The Google Mobile Ads SDK was initialized without an application ID.

at Corona-3564 , it works well .

Hi, I just ran into this today.  After following the Google instruction page, I added the required new plist entry to my build.settings file:

iphone = { xcassets = "Images.xcassets", plist = { UIStatusBarHidden = true, UILaunchStoryboardName = "LaunchScreen", GADApplicationIdentifier = "YOUR\_ADMOB\_IOS\_APP\_ID" } },
Of course replace YOUR_ADMOB_IOS_APP_ID with your actual Admob app ID for iOS .
After that, the Corona build process warned about an unknown plist entry:
WARNING: unrecognized key: settings.iphone.plist.GADApplicationIdentifier (string)
however it was just a warning and the app ran OK.
The admob docs page does not yet reflect this:

Thank you so much- this post really saved my bacon.
My app was running fine when I built it with 3555, but when I built it with 3575, targeting iOS 13.3 it would crash right after the launch screen, no error message, nothing useful that I could find in the console. I’d been chasing the problem all day and adding that one line to the plist was all I needed. Whew! 
          
Thanks for this solution, after full day destroying my app , i added this one line and it worked like magic
