  HN crowd told me they’re porting to swift. When I asked “why not Rust”, they said the C++ code was very OOP, so it was easier to port to swift.

    Which probably means it uses deep inheritance hierarchies since that is the one thing that does not exist in Rust (and for a good reason).

      You can do deep hierarchies in Rust, the thing Rust doesn’t have is implementation inheritance. Or more precisely said implementation inheritance that relies on anything but the interface (traits can have default methods but they’re part of the trait definition, not any implementation).

        Yes, most likely they use it for implementation inheritance which is sloppy anyway since it usually violates the Liskov substitution principle and also most OOP languages that have that concept tend to have issues around co- and contra-variance in either function parameter and return types or containers or both.

    I’m not a dev but does Swift will restrict it to Apple platforms since it is Apple language?
