Sometimes people mistake Swift for Xcode and vice versa. If compiler can't figure out type in reasonable time, give it some room to breathe by adding a clarifying type definition. I don't like to fight the compiler trying to bend it to my will. I am happy to offer extra help by clarifying types – magic costs performance. Compiler gives back by blazingly fast builds.

By the way, I am impressed by speed of Swift 6 project builds on Apple Silicon Macs. My non-trivial apps using a mix of Swift/C++/C files (hundreds and hundreds) get compiled in nearly real time. Feels good.

Mistaking Swift for XCode isn't the issue here. Swift is great, I'm just pointing out the issues I've had with it in large projects.

Right, but that's the problem - it's the only language I've used where this is something you have to worry about, and it's not like the type system is more powerful. And often, the issues stem from external libraries outside my control. Better compiler errors would help mitigate the issue.

There's a lot to like about Swift, but I also think it's productive to identify the parts that compare unfavorably to other languages.
