This! Also, for new APIs Apple reduces (or does not provide) Objective-C documentation.

I really tried to love Swift, but in the end I ended up with 1 project using Swift/SwiftUI, and all the other apps I started to write, I rewrote in Zig or Rust, because the Swift compiler kept giving me vague error messages with no hint which Swift file was the culprit or/and which line/column the error was.

YMMV
