On November 19th, Apple began returning an "Invalid Binary" error for a good deal of apps we uploaded to the App Store. It soon became clear that the error was related to our Google+ integration, introduced on the 4.0 source code this April. Read this article for answers to some of the frequently asked questions about this topic.
If I Received an Invalid Binary Error from Apple for One of My Apps, What Needs to Be Done?
Your app will need to be rebuilt and resubmitted to exclude Google+ integration. We were planning to remove the integration for our next iOS source code anyway, but have completed this sooner than expected due to the error. Any apps uploaded as of yesterday (November 20th) are using a slightly adjusted source code that doesn't include the integration, and won't encounter that error.
I Received Another Error: "Your app has one or more issues..." What Does That Mean?
Some apps were partway through the review process when Apple made the decision and received this warning message instead. If you got the email above, that's simply a warning message, not a rejection. As long as your app is currently Waiting for Review in iTunes Connect, you can disregard it completely.
So Google+ Integration Is Gone?
Yes, the integration was removed for Android apps as of last Friday (November 14th) and iOS apps as of yesterday (November 20th). Any apps published & uploaded after those days will not contain Google+ integration, and customers can disregard the Google+ ID field in Step 5.
My Live App Already Integrates with Google+. What Does That Mean for Me?
Any live apps published & uploaded before those dates will still contain the Google+ integration options, and the Google+ ID field in Step 5 will remain for at least a few months to accommodate those apps that are already using the feature. However, we recommend phasing out of this integration option, since we'll no longer be developing for it and will most likely remove it completely in the coming months.
