Facebook, within a few weeks, plans to release an open source library intended to help developers build native Apple iOS apps with smooth, responsive user interfaces.
In a closed beta stage of release at the moment, Async Display Kit is part of Facebook's Paper interface application for iOS. Async Display Kit defines a UI in a separate thread, so it does not hold up the user experience; when ready, changes are mapped across to the main thread.
"[The library offers] a completely new take on the way in which you can design the user interface of iOS apps," said Facebook open source technology lead James Pearce, in an interview Tuesday at the O'Reilly Open Source Convention (OSCON) in Portland, Ore. Users get a fast, fluid 60-frames-per-second-type experience, with better scrolling of applications on their devices, he said.
