@nascif - there had been recent discussion about this again. You can find some of it by searching for kivy in the forum. This other project has SDL/Pygame working on IOS. However, the rest of the info in this thread remains true. You still have to make everything link into one big static library in an IOS App and this is a lot of work and then ongoing maintainence.
I looked at kivy recently and found that they don't have an IDE that runs on IOS - only on desktop OS's. This is where Pythonista really shines and keeps getting better and better.
Since you mention Numpy, I would love to read an article from omz on what his experience was getting this port done.
