iOS's smoothness doesn't come from being AOT. If it did you'd have seen a huge difference in responsiveness in Android between interpreted, JIT & AOT, but you don't. Raw code perf does improve from interpreted -> JIT -> AOT, but the rendering is part of the platform not the app and that's been C++ since the beginning. dalvik's GC was a big problem for smooth UIs, though.
