Undefined symbols for architecture arm64 Google AdMob in Version 6.7.0

Question

Okay so google AdMob API is supposed to work now for arm64, but I am getting this error.

Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_ASIdentifierManager", referenced from:
objc-class-ref in libGoogleAdMobAds.a(GADDevice.o)
objc-class-ref in libGoogleAdMobAds.a(GADGestureIdUtil.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I've searched on Google and many people suggest to avoid using 64Bit capabilities. But now the API is supposed to work so I don't see why I should do that.

I am really stucked here.

Answer 1

Okay so I found the solution.

Google guide iOS developers on how to implement AdMob SDK, however they are missing some info. They tell you it's mandatory to add these Frameworks:

   - AudioToolbox.Framework
   - MessageUI.Framework
   - SystemConfiguration.Framework
   - CoreGraphics.Framework

To solve the error I added this ones also:

   -CoreData.Framework
   -AdSupport.Framework
   -CoreTelephony.Framework

Answer 2

Along with -CoreData.Framework and -AdSupport.Framework I also found that I had to add the -CoreTelephony.framework in order to get a clean build of the sample app that is provided. (Banner Example)

Answer 3

The Google Mobile Ads SDK library references the following iOS development frameworks which may not already be part of your project:

• AdSupport
• AudioToolbox
• AVFoundation
• CoreGraphics
• CoreTelephony
• MessageUI
• StoreKit
• SystemConfiguration

Make sure all of them are added to your target > Build Phases > Link Binary With Libraries.
