iOS 9 introduced multitasking, which allows apps to be used side by side on certain devices. Along with this came a number of new APIs for handling transitions between different screen configurations. However, integrating these new APIs in an exiting codebase can be trick, and often requires rethinking the way a component is structured. This talk will introduce multitasking, cover the new APIs available to handle different scenarios, and walk through some gotchas when adding support for multitasking into existing applications.
