Apple introduced a new programming language called Swift. One of the key features is full interoperability with existing Objective-C code which allows to easily integrate existing frameworks and libraries into applications built with Swift.
Below video demonstrates the process of adding and using Worklight native API to an iOS application built with Swift. As usual - watch it in HD for a full screen resolution.
Note that iOS8 and XCode6 are still in beta phase and therefore not officially supported by Worklight, so this is just a small proof of concept.
(I'll be doing some work with XCode6 myself, so will post some further articles on my findings during Q3/Q4 this year)
