> Swift didn't replace Objective C Give it time. Unlike the other examples one company (Apple) has full control here. There is basically zero demand for Objective-C outside of development for Apple platforms. Apple is already making Swift only features and APIs and is deprecating older things. Obj-C is arguably legacy already, but still works fine. I’ll bet plenty of money there will find a day when Apple says “This is it, next release it’s out of the toolchain”. Existing developers often have Obj-C code (I do), but the biggest user is Apple. So they can’t kill it tomorrow. But its days are numbered. No one is in that kind of position with C/C++/JS/Java.
