Yes, it’s “official”.

It wasn’t officially supported in iOS 7, only from iOS 8 (when Xcode started to provide a iOS framework template). There are applications published in the AppStore that use dlopen. Now, the framework must be code signed and packaged with your application, so this doesn’t concern third-party plug-ins, or anything you’d download from the internet. On the other hand, in iOS 9 they started to allow modular downloading of applications in the AppStore: you can install eg. a game with the first levels, and only download and install further levels modularly once the previous ones are completed; http://ddeville.me/2014/04/dynamic-linking <http://ddeville.me/2014/04/dynamic-linking> -- __Pascal J.
