From the bits of Rust code I've seen, it seems like while memory management isn't exactly manual, it needs to be given a fair amount of thought, what with borrow semantics and such. When writing Swift I very infrequently have to give it any thought at all, beyond avoiding retain cycles (which is usually as simple as using weak references to self in closures).
If you are going to use it like a garbage collected language, you would be better served by one of the slew of other languages with the same features but which are easier to use. The memory management is what sets Rust apart.
