This new SDK doesn't help advertisers or users. Being able to assess the quality of users coming from different ad networks is crucial for any advertiser to assess the quality of their spend. Some ad networks might generate high quality legitimate users, while others are fraught with click fraud, or low quality users. Since an advertiser isn't able to tell which users came from an ad, no advertiser will adopt it.<p>If Apple really wanted to protect user privacy, they would provide something similar to the iAd Framework they provide for their own Apple App Store Ads, where the app can ping the iAd Framework to tell if the user installed the app from an Apple App Store ad and monitor the users long term engagement, while Apple handles all the attribution on their end. If Apple took the same approach they use for their own App Store Ads it would be a big step forward in helping protect user privacy and eliminate the need for all the fingerprinting, etc that some ad networks do.<p>The fact they didn't, I feel this is nothing more than a fluff PR move by Apple and does not seem genuine.
