Apple technology evangelists and engineers started a tour around the world and will stop for two events in Germany, too. At 10 November they are in Berlin and on schedule are user interface design, development tools and UIKit.
A few days ago I received an email that my registration is confirmed and I will attend to this event. I am excited to hear what new information I will get there. Reading documentation is every time a good source of knowledge but listen to experienced teachers can speed up the learning process very much, inspire to new ideas and help to find out the pitfalls without falling in every single one.
