[SOLVED] iOS - Error(s) Integrating IMA3 VAST and DFP ads on the same project

iOS - Error(s) Integrating IMA3 VAST and DFP ads on the same project

I'm trying to integrate IMA3 VAST ads into a project already working with adMob.

While compiling I get the following error, as well as a few other duplicates:

duplicate symbol _OBJC_CLASS_$_GAD_GTMStringEncoding

I've tried using the latest of both the AdMob and IMA3 pods:

pod 'GoogleAds-IMA-iOS-SDK' # 3.4.1
pod 'Google-Mobile-Ads-SDK' # 7.17

Any idea?

UPDATE:

Tried reverting to older IMA3 SDK:

  pod 'GoogleAds-IMA-iOS-SDK', '3.3.1'
  pod 'Google-Mobile-Ads-SDK', # 7.17

App compiles fine but crashes on start on:

dyld: Library not loaded: @rpath/GoogleInteractiveMediaAds.framework/GoogleInteractiveMediaAds
  Referenced from: *REMOVED*
  Reason: image not found

UPDATE2:

As per a suggestion by a member of the IMA SDK team, I tried the deprecated GoogleAds-IMA-iOS-SDK-For-AdMob. Even though it's deprected and the docs state that it's no longer needed.

pod 'GoogleAds-IMA-iOS-SDK-For-AdMob' # 3.4.1

App still crashing on same error.

UPDATE3:

A Google engineer named Veer identifying himself as part of the IMA iOS SDK team has responded to my Google Groups thread about this issue.

He acknowledged the issue and claimed that it was fixed on 3.5. Sadly this is not the case.

Solution

The only thing working for me now is using an old version of the deprecated bundled SDK:

pod 'GoogleAds-IMA-iOS-SDK-For-AdMob', '3.3.1' # Implicit dependency on AdMob SDK. 3.4.1 causes "library not loaded" crash on start

I'll post an update if and when Google sort this mess out.
