iOS game development

I have had this idea for a long time now, I would really love to develop a RPG Pokemon like game for iPhone but I seriously have no clue on what to do or where to start.
I have had a look at Xcode and Coco pop (I really hate coding.) so I have come here to Unity because apparently it would be easier to grasp so to say. I have looked at the other game makers like Game salad and Stencil and I would like a more professional program.
Any advice for other game dev programs that is suitable for my needs? I use a mac btw

I was wondering if anybody could really help me out and give me some advice on creating such a game for iPhone and iPad?
and also I have a lot of time on my hands so I don’t mind on how long it will take, this project is for my own purposes and entertainment I will not be selling it.
I am a Graphic Designer so graphics will not be a problem, I have minimal coding experience if you call action script 3 coding.

Action script may be a good start for you to grasp UnityScript (cut down javascript). Have a go at Unity. It will take a month to grasp its nonsense but when that is aside you are away. Unfortunately you will need to do some coding but the good news is you won’t need to be a pro up-front.

As Unity3D supports lots of platforms, it handles the platform-specifics for you and pretty much enables you to deploy your program with minimal fuss.

With iPhone and iPad though, it is required by Apple that you pay for their dev license before you can deploy your game on to the device.
