WWDC 2013 101: Platforms State of the Union

Released:

iOS7

AirDrop

New UI

3 big ideas: Clarity, Deference (getting the chrome out of the way of the content), Depth (parallax, blurs, sophisticated animations) 

4 things to pay attention to: Content (shows through the bars) , Metrics (cells are going edge to edge), Buttons (using coloured text more than buttons, don’t have borders), Pickers (pops in inline with content)

Text Kit: complement to WebKit

Animations: dynamics, transitions (e.g. View Controller transitions), motion effects (UIMotionEffects – e.g. for parallax effect), UIKit Dynamics (physics engine)

Multitasking: new multitasking interface, background fetch and transfers;
