> I wouldn't buy into much Apple marketing regarding its performance though, I wouldn’t make claims on Swifts overall performance, but just it’s memory usage (really Obj-Cs) and particularly for GUI development. Java’s GCs have always been very memory hungry, usually to the tune of 2x. Same with .Net. Though to be fair Go’s and Erlang’s GCs have much better memory footprints. Erlang’s actor model benefits it there. Agreed, they’re all better than manual memory management.
