Nate Swanner thinks iOS 10 will be faster than previous versions. It all has to do with a new set of API’s in iOS 10.
During a session at WWDC, Apple noted the reason for those dropped frames was that content is loaded just before it lands on-screen. Those cells you’re about to scroll to were loaded milliseconds before you got to them.
Now, Apple is loading those cells well ahead of the time you scroll to them to make sure that when they do land on your screen, the scrolling performance and load times aren’t noticeable. Apple says 60 frames per second is ideal, but existing scrolling performance often misses that mark.
A somewhat simple change which results in a visual improvement.
