IOS SDK - is it still a thing?

Hi ya'll,

I'm trying to help a dev get set up to use the community API (yay!) within an iOS app (yay!). I'm not sure if I should set up a "Web App" in the admin console or an "iOS App".

The little bit of research I've done on the iOS SDK (which is why you'd use the "iOS App" option, right?) leads to dead links like https://github.com/lithiumtech/li-ios-sdk-core/wiki/Getting-Started-with-the-Community-iOS-SDK 

So... is the iOS SDK still a thing? Should I set that up for our devs or just a normal web app?

Thanks!
