The third issue of objc.io arrived this week and Chris Eidhof, Daniel Eggert and Florian Kugler are joined by Joe Conway and Ole Begemann to discuss everything view related. The quality of articles in objc.io is consistently excellent and this issue is no exception. Read it all, then subscribe so I don't have to link to it every month.
I am not a game developer so I hadn't really given this topic much thought but I really enjoyed Steffen Itterheim's analysis of why a physics engine is a bad choice for a 2D platform game. All of the reasons make sense, I guess I just hadn't thought about it from this perspective before and it's always good to look at things with a different perspective every once in a while.
Interesting library from Mattt Thompson for real time, streaming, event based JSON updates from a web server. Includes both a server side implementation based on Rack and a preview/RC of AFNetworking 2.0 which is worth a look even if you don't need the functionality of Rocket as it has had some major revisions which are not entirely related to this project.
