Swift has a real performance problem, it doesn't seem competitive with other "systems languages" Is the goal to make it faster later? What can be done to get c

  Swift is quite fast as an app programming language. I’ve never understood why anyone could consider it a systems programming language with a straight face. But to say that it has a “real performance problem” is a bit of an exaggeration. Compared to the many other languages out there, it’s faster than most.

    Probably because that is one of the states goals as voiced by the languages creator

      That was a long time ago, I thought. The word "systems" was removed from the swift website years ago when it was clear that it did not really have that priority.

        > The goal of the Swift project is to create the best available language for uses ranging from systems programming, to mobile and desktop apps, scaling up to cloud services. > Fast. Swift is intended as a replacement for C-based languages (C, C++, and Objective-C). As such, Swift must be comparable to those languages in performance for most tasks. Performance must also be predictable and consistent, not just fast in short bursts that require clean-up later. There are lots of languages with novel features — being fast is rare. Those are literally the stated goals. It does not get more clear than saying "Swift is intended to be a replacement for C-based languages (C, C++)..."
