Apple increases maximum app size to 4 GB

Federico Viticci, MacStories:

Over the years, the maximum size of 2 GB for apps forced game developers to drastically reduce the graphical capabiltities of their games (see, for instance, the original BioShock port). With Metal and more powerful iPhones and iPads, it only makes sense to let developers create more advanced iOS gaming experiences with fewer compromises.
