My friends and fellow Berlin-based developers Chris Eidhof, Florian Kugler and Daniel Eggert have just published the third issue of objc.io. objc.io is still a very young platform, but I feel it has already established itself among the best iOS development-related websites.

Each month, the guys pick one topic and then publish several articles that discuss different aspects of the overarching topic. I have already learned a lot of stuff from reading the first two issues.

This month’s issue is all about iOS’s view layer and deals with both very technical and more practical stuff. I am glad to report that I am one of the guest authors in this issue, with an article on UICollectionView layouts. The other guest is Joe Conway, who wrote about Understanding Scroll Views. Check it out!
