Recent revisions to the iOS developer agreements caused considerable controversy by restricting which programming languages could be used to develop iOS apps. Those changes also restricted what kind of analytics data could be collected by developers and advertisers. Now, however, Apple has backed off on its position: it will relax these rules in order to give developers more flexibility. Additionally, Apple will now actually publish a list of app review guidelines for developers—the first time the company has done so since the App Store launched more than two years ago.
