Clicked this link to recommend this exact course. It really helped me understand the basics and get going, and I am really close to launching my first app. Chris is also a nice guy was happy to answer questions I had about the course on Twitter. this is great starting point, and from there google and stack overflow are your friend, don't be afraid to ask questions. Raywunderlich.com also has some pretty solid tutorials, complete with memes.
My number one recommendation: On iOS, go Swift. It's friendly.
For backend, Firebase will make your dreams come true - once you can figure it out.
