Ya'll need Jesus-- also known as bootstrap and jQuery. There is WAY to much javascript on this page... I can't imagine it's needed. UI reworks in the mix?

The answer will change... so lets hope often.

I would learn objective-c first because you can get more help with it. People all over the internet have been doing it for a long time. It won't be obsolete for at least a decade, so don't stress about swift being the new way to do the same things. Find tutorials online or get torrents of books/buy them. Dream up your own micro-projects, when you get stuck http://stackoverflow.com/ is your friend. This site has saved me MANY times, usually within minutes. take a look at other peoples micro-projects and full fledged ones on https://github.com/ but above all, right some code EVERYDAY.
