v7.8.0 SDK gives error: Undefined symbols for architecture arm64: "_OBJC_CLASS_$_CBUUID"

[Zhiping Deng]

Hello, 

Today I upgrade google mobile ads sdk to latest v7.8.0, but the build failed with the following error:

Undefined symbols for architecture arm64:

  "_OBJC_CLASS_$_CBUUID", referenced from:

      objc-class-ref in GoogleMobileAds(flat-arm64)

  "_OBJC_CLASS_$_CBCentralManager", referenced from:

      objc-class-ref in GoogleMobileAds(flat-arm64)

  "_CBCentralManagerOptionShowPowerAlertKey", referenced from:

      l919 in GoogleMobileAds(flat-arm64)

ld: symbol(s) not found for architecture arm64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

And v7.7.1 is ok.

Hi Zhiping,

I would suggest you to use our sample app and try to replicate the issue. This could be due to you Build Settings not being properly set. If you are still unable to resolve this, then do send us your sample app and we would have a further look into it.

Thanks,

It's funny.  your sample app's Podfile is outdated:  

  pod 'Google-Mobile-Ads-SDK', '~> 7.5'

I'm reporting issue of version 7.8.0. 

Somebody else encountered the same problem:

Please take a look at it.

Hi Zhiping,

I have only referenced that sample app but I have updated to the latest v 7.8 of the SDK when I was testing. I have even tried to implement it manually and was still unable to reproduce the issue. Have you tried to create an empty project and only implement the Mobile Ads SDK? Do let us know if that fixes the issue.

Thanks,

Just add the CoreBluetooth and SafariServices to your frameworks (in Link Binary with Libraries). I have set SafariServices to Optional, since this is only supported from iOS9 upward. 

@Admob: this should be updated in the integration instructions.

Hi guys,

The team is aware of this issue and is working on fixing/updating the documentation and specs. For now, adding the two frameworks - CoreBluetooth and SafariServices would fix the issue.

Thanks,
