Does it? I am yet to update to the new iOS because too many things break with early releases, and I've gotten tired of broken releases. But right now I can swipe my phone to the left, and get a sub-second access to my camera. There's no way it's not pre-loaded for this to work so fast.
My question is whether developers, who are not Apple, would be able to load the camera with the same speed that Apple. Does iOS load Camera in the same way that Apps do, or does iOS have access to lower-level API?
I don't have the answer, but I'd be curious to know if someone's got the know-how.
