Do those get optimized now? As far as I know, objc_msgSend was never optimized out (as of a few years ago when I was doing iOS dev) because any method can be swizzled and replaced at runtime.
- mucholove 5y agoThere is some sort of devirtualization that might bypass it. When they announced, Twitter was going crazy about how it might kill ObjC dynamism. However, what I was to was that you can store the method in a variable, and call it directly, thus bypassing objcMsgSend. :)
