Key quotes
· 5 pulledThis year, I decided to use Advent of Code to learn the language Swift.
Tooling in general is quite good, but the language server is still a bit immature compared to Rust's rust-analyzer.
Swift's type system is quite powerful, but also quite complex.
The concurrency story in Swift is quite good, but also quite complex.
Overall, I think Swift is a good language for learning, but I'm not sure I'd use it for production code.
