Great news….no wait, amazing news I just got form the Unity3D CEO David Helgason. Apple has lifted their restrictions surrounding development tools, which I believe is the right choice. As Helgason says, after all you could create and build really crappy apps with just xCode, and I truly believe that you can actually create incredible apps with Unity3D.
I have been working with Unity3D engine for about six months now, on a very fast and intense learning process to the point that I’m actually able to apply my interactive application development knowledge to Unity3D game development, which basically means reusable code, structured and easy to read and maintain scripts, loosely-couple game states and modules and most of all, the most fun I have had coding.
Apple, you made my day !!!!
