- It is no longer simple, Swift 4 onwards have been piling the complexity higher than I previously thought possible. I would never recommend it as a language to teach. I would have with Swift 3, but 4 to now - absolutely not - too complex.
- It was never open, but the language features dropped on the community to support SwiftUI cemented the fact that outside contributors are not treated with any respect. Worth reading - this is from the guy who created the language! https://mjtsai.com/blog/2022/02/22/why-latter-left-the-swift...
- Swift on the server is dead. Swift on other platforms has dreadfully poor support. It would and should be rejected for anything outside of iOS apps.
Kotlin or Rust are much much better choices that live in the same space that Swift projects would be considered for.
