Swift is underrated, it's a good alternative to C++ for those not interested in Rust.
Noted that as well. Could be a reflex of swift’s improved memory safety capabilities.
Wouldn’t that make it slower than if in C++?
Swift can be just as fast as C or C++. The danger, in my experience, is that it's not always clear what the performance implications of the language's many convenient abstractions are. (A random example, I recently improved one code path by over an order of magnitude by replacing some serialisation that used Codable with hand-rolled code. Still 100% Swift, just paid a lot of attention to avoiding RTTI and allocations.)
Swift had automatic memory management, so yes ()
(: Although anything can be made as slow as python yada yada)
A bit slower is good if it is safer from exploits than C and C++.
