Coming soon to a (small|big) screen near you

Yet again, this year has been huge for iOS developers. Not only did Apple release Apple Watch, and brought apps to small displays attached to your wrist, but they are also going after your big screens with the imminent launch of new app-enabled Apple TV.

In this keynote, Paul will discuss the recent Apple announcements – like the the new tvOS, iPad Pro and Pencil – and where all of these fit within Apple’s yearning for your hearts and abode. We will also discuss the various changes in the Apple SDKs, tools and business, and try predicting next year’s developments – HomeKit anyone?!

32. Benefits
    • Safety
    • type safe language - type checks performed at compilation
    • Optimisation
    • compiler optimised for performance
    • language optimised for development
    • Expressivity (a.k.a. Magic)
