Error (Xcode): Undefined symbols, After upgrading from version 5.1.0 to 5.2.0 #1185

After upgrading from version 5.1.0 to 5.2.0, a issue occurred: the iOS project failed to compile directly.

The error message is: Error: CocoaPods's specs repository is too out-of-date to satisfy dependencies. To update the CocoaPods specs, run: pod repo update

After I run this command : pod deintegrate and pod install --repo-update, and build iOS project， and another issue occurred：

Error (Xcode): Undefined symbols:
Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

Plugin Version 5.2.0

After repeatedly comparing the original project with the updated one, I found that the issue lies in the Other Linker Flags option under the Build Settings of the iOS project. When updated to version 5.2.0, an additional flag "Google_Mobile_Ads_SDK" appears, while in version 5.1.0, it was only "GoogleMobileAds" without the "Google_Mobile_Ads_SDK" flag.

Plugin version 5.2.0 uses iOS Google Mobile Ads SDK [11.10.0](https://developers.google.com/admob/ios/rel-notes) which requires >= Xcode 15.3. Updating your Xcode should resolve the issue.

Updating the XCode version can solve this issue. Thank you guys.
