Hi Sky Choi,

Thank you for providing the sample project.

I ran the project and the issue you have mentioned was reproducing but after making some changes the project ran successfully.

Change is  replace “-objc” with  $(inherited) in other linker flags.

Steps: Build setting -> other linker flags "$(inherited)".

Please reach out to us, if you need any further assistance.

Hi,

In my real project there have other SDK, like Firebase analytics, Crashlytics, Smaato
these SDK need me add "-objc" in other linker flags.
Could you give me another solution?

Thanks

Hi Sky Choi,
Thank you for getting back to us.

Sure,  you can use both -objC and  $(inherited) in other linker flags. Also, It is advisable to incorporate the pod ‘GoogleMobileAdsMediationFacebook’ within the Podfile and subsequently execute the command ‘pod install –repo-update’. For more information, Kindly refer to Integrate Meta Audience Network with bidding. Additionally, I would appreciate it if you could provide information regarding the source from which you downloaded the MetaAdapter and FBAudienceNetwork libraries.

Hi,

Thank you for your reply.

Unfortunately our company not allow us to use cocoapods in our project. I cant set both -ObjC and $(inherited) in different SDK. Any advice for me to handle this situation?

I manual download FBAudienceNetwork in this site. V6.15.0

https://developers.facebook.com/docs/audience-network/setting-up/platform-setup/ios/get-started

I manual download MetaAdapter in this site. V6.15.0.0

https://developers.google.com/admob/ios/mediation/meta

I manual download Google mobile ads SDK in this site. V11.2.0

https://developers.google.com/admob/ios/download

Thanks

Hi Sky Choi,

Thank you for providing information regarding the source from which you downloaded the MetaAdapter and FBAudienceNetwork libraries.

I see that you are making use of a manual download framework and swift package manager at the same time. Use one of the following methods to import the Google Mobile Ads SDK.

CocoaPods (preferred)
Swift Package Manager
Manual Download

There are 2 errors in the sample project you have provided 

1. Missing package product 'GoogleMobileAds'
2. Linker command failed with exit code 1 (use -v to see invocation) undefined symbols due to Meta Adapter.

For 1st error remove the existing GoogleMobileAds framework and add it again which you can download from GoogleMobileAdsSDK.zip, because the existing framework is grayed out.
For the 2nd error: 

1. I’m able to run the Google sample Objective C project successfully either by removing or keeping -ObjC in other linker flags. 
2. I’m able to run the Google sample Objective C project successfully with the FBAudienceNetwork and Meta Adapter frameworks added by removing -ObjC. 
3. Xcode is throwing an undefined symbol error only when -ObjC is added to the project which contains FBAudienceNetwork and Meta Adapter frameworks and the error is also around Meta Adapter.

I would recommend reaching out to Meta's product support team. Please note that we can only assist with technical queries/concerns related to the Google Mobile Ads SDK. Meanwhile, if I find any solution I’ll keep you posted on the same.

My tryouts are below and none of them didn’t work:

• Adding -ObjC & $(inherited) in other linker flags
• Added Library Search Paths to the target's Build Settings 
• Deleting derived data
• Adding EventKitUI, and AdSupport in Link binaries with libraries in build phases(which is not relevant but in some sources some devs stated it worked). 
• Build Active Architecture only to YES, NO.

Hi,

I find the solution, if we use FBAudienceNetwork static SDK than it works.

Thank you for all your assistance
