Garbage collected languages are still better-suited for certain things. You can make most of those things work well enough in Rust by using Rc<>, but a) it's really clunky, and b) reference-counting has caveats, like the fact that it doesn't work for circular references. Swift solves (a), but not (b). On top of that, for programs where you need to constantly allocate/deallocate, I believe (could be wrong on this) that amortized over time, sweeping GC is quite a bit more efficient than reference counting. This is extra relevant once concurrency gets involved, because now your reference-counters have to use an atomic or locking mechanism. In short: I'm pretty sure GC isn't going anywhere, even if some of its usecases start to get covered by non-GC'd languages.
