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.
You can also try https://github.com/rahuliyer95/iShowcase this is a similar implementation of ShowcaseView for Android on iOS.
You can also check out my implementation at https://github.com/scihant/CTShowcase
It's developed using Swift 2.0 and can also draw animated highlights such as this one:
Update:
It's now updated for Swift 3.0
You can check a small library (MaterialShowcase on Github) that I created when developing my company app.
There's a framework we've been working on that might be useful, BubbleShowCase. Check it out and don't hesitate to leave any feedback.
Try WSCoachMarksView. It is very easy to use, e.g.:
DDCoachMarks is a simple and flexible iOS alternative:
