Swift is the de-facto future replacement of Objective-C for Apple ecosystem. It's got a while to go yet - a stable ABI for one - but once that happens (with Swift 3 later this year) then you'll start to see it take off. Plus, since it was open sourced it has been made to run on Linux and Raspberry Pi devices and has attracted a hugely varied and vocal community.
