Google has released Google Analytics Services iOS SDK v3.03c, which provides an option to remove the AdSupport.framework dependency.
Apps that need to access the advertising identifier (IDFA) string and advertiser tracking enabled flag as part of their Google Tag Manager implementation should link to libAdIdAccess.a, now included in the GA Services SDK download.
