I recently spent a couple of weeks in Swift land to see what it's all about; but from my experience it's still a mine field of exceptions and hoop jumping. I feel that the problem with both Rust and Swift is that they're aiming so hard for perfection that they're missing the point of the exercise; which is to make it easier to write good code, period. Wasting half your energy-budget on spoon feeding the compiler is just as bad as spending it on managing memory manually in C.
