WWDC 14 has been called the most important WWDC since the announcement of the original SDK in 2008. Apple announced a new language, additions to the APIs available, and structural changes to iOS codebases. This presents a set of challenges to codebases of substantial size which were structured according to best practices in previous versions of iOS. If you must maintain a legacy application with backwards compatibility, what improvements are available to you and which are dead ends?

The situation is still in flux. We intend this talk to clarify the situation for developers and project managers so that they know what is easy, difficult or impossible when transitioning legacy projects to Swift and iOS8.

Diving into the feasibility of using a single code base for generating multiple front-end applications.

We'll discuss using React and React-Native for building apps that provide a consistent experience across native, mobile and desktop web.

Using React and React-Native as the UI layer upon a shared JavaScript core codebase can greatly improve your organisation's delivery of new features to customers.

We'll talk about our migration strategy for the new apps replacing our existing apps, piece by piece. Not slowing down our continuous release of features to customers while replace the apps.
