If you look at NSHipster and other sources in the iOS community converting their code samples to Swift only months after its initial release in 2014, it says something about the pent-up demand for a nicer language than ObjC. Plus Swift seems to be designed for ObjC devs to have an easy transition, although slightly less dynamic (and unsafe).

Demand for iOS development could be tapering due to app market saturation; saw a post recently around here about that.
