Not for all cases, sure. It would be challenging to write an OS kernel or low level device firmware in Swift, but for a lot of other use cases it is absolutely a viable alternative to C and C++.
Apple is doing exactly that. They’ve already shipped stuff written that way. I think the Secure Enclave code is now Swift.
I’m pretty sure they have extra stuff on top at the moment to help them write ultra-strong/safe code that the released language doesn’t support directly yet.
But they are moving in that direction. Just because most people use Swift as a language where they don’t have to worry about memory allocation and with the large standard library doesn’t mean that’s all it can do.
