Yeah, on the flip side Apple is putting some serious engineering resources / funding in it. With Rust it is always creating committees, teams , sub-teams and so on and to actually do implementation there are far fewer resources.

So overall things balance out even if not big win for either.

Swift: Close process + big funding -> fast implementation / less feedback Rust: Open process + little funding -> slow implementation / lot of feedback

Also even with lot of feedback many community members in Rust are already claiming very new features like Async in Rust are deficient in parts and feels rushed.
