I have created this sample Swift framework which has GoogleMobileAds in it integrated through Cocoapods. I have a class NativeAdView which inherits from GADNativeAdView.

import GoogleMobileAds

@objc public class NativeAdView: GADNativeAdView {
    
}

I also have a sample target which is an Objective-C app. I import the framework header as below in my AppDelegate.m.

#import <SampleFramework/SampleFramework-Swift.h>

Now when I run the Objective-C target it throws an error inside the file SampleFramework-Swift.h

@import GoogleMobileAds; -------- Module 'GoogleMobileAds' not found.

However, if I change the parent class of NativeAdView to anything other than a Google ad class the error goes away and the build compiles and runs successfully.

Also @import GoogleMobileAds; line goes away from SampleFramework-Swift.h file

I can't figure out what is happening.

First, update bundle identifiers of your targets SampleFramework, SampleSwift, SampleObjc to be different.

Try updating Podfile as follows. Cocoapods works this way that in your setup you have to specify 'Google-Mobile-Ads-SDK' for every target which uses it, but to avoid copying that line, you can use abstract_target so the dependency is automatically added to all targets inside:

use_frameworks!

abstract_target 'Common' do
  pod 'Google-Mobile-Ads-SDK'

  target 'SampleFramework' do
  end

  target 'SampleObjc' do
  end

  target 'SampleSwift' do
  end
end

But this way you will face a runtime warning "Class APMAdExposureReporter is implemented in both ...", but the app will work, the warning doesn't cause real problems - it's discussed here, but personally I don't know the best practice how to deal with it.
