Hi I'm interested in trying out some iOS/OS programming (creating apps). May you give me some advice which program to use? I've heard of "xCode" which I can download in the Mac App store. Is this the right one? And where can I save my created Apps? Where can I host them? And in which case I'm autorised to set a price for my apps? I don't think that I'm gonna start up with my first App and that it's becoming a best-seller, but I'd like to know all the possibilities thanks for your answers.
