Thanks for sharing. I agree in general,

But for me language is not a problem at all. I mean that you have a lot of pre-requirements to start developing for iOS.

And the stuff, except writing code feels much more restricted. AppStore is a walled garden itself.

But yeah, Objective-C was something...

What prerequisites are you thinking of? Nowadays, all you need is a Mac, download Xcode, and go. You can't do /everything/ if that's as far as you go, but if all you wanted to do was flesh out an idea, that would get you started. And how's that's any different than getting a computer, installing Android Simulator, and starting a new project?
