iOS 9 finally brought split-screen views to the iPad, but it’s still not nearly as useful as the windowed multitasking views you get on a Mac. Developer Steve Troughton-Smith has come up with a much better solution with a new proof-of-concept called iOS window management that would bring the joy of working in a windows environment to the iPad.
Apple already has the foundation built thanks to UIKit. It only took Troughton-Smith 500 lines of code to build the concept with the UIWindow subclass, allowing individual app screens to be resized an overlaid on top of each other.
