Apple didn't replace Obj-C. They added Swift alongside it. Literally nobody is being forced to switch, and all of Apple's frameworks are still written in Obj-C (they can't be written in Swift until Swift has ABI stability). Yes, Apple's weight helped Swift tremendously. But people are switching from Obj-C to Swift because they think it's better, not because Apple's making them. > How much of Swift is written out of Apple ecosystem? Not much. Not much yet, because the Linux support is still missing a lot, but it's being filled in quickly, and a lot of people seem to be excited about being able to start using Swift on Linux.
