Is there an equivalent of Androids ShowcaseView for iOS?

There is a project for Android on Github: https://github.com/amlcurran/Showcaseview According to the readme: The ShowcaseView library is designed to highlight and showcase specific parts of apps to the user with a distinctive and attractive overlay. This library is great for pointing out points of interest for users, gestures, or obscure but useful items. I would like to know if a functionally equivalent one exists for iOS. It would be useful to give users a quick tour of an app. Typically app intros are handled with a few swipe screens. Think Uber and Duolingo. Google and Stackoverflow searching returns nothing meaningful. If I had time I'd work on this as a side project. Edit: I've ended up using github.com/IFTTT/RazzleDazzle which works for both Swift and Objective-C.
