There are several ground-up replacements in the Swift overlay already, if you look at the various value types that have been introduced to replace various NS classes (granted, some of them call through to the underlying Foundation API for their implementation, but others don’t). As long as we eventually end up supporting NSProgress’s interface, something like this should be possible to drop in as long as we do it before the ABI stability lockdown.
In any event, I BSD-licensed the code, so it’s free to use whether or not Apple ends up using it, so feel free to give it a try (for performance testing, be sure to compile in Release mode, as it does much better with the optimizations on). If you find any bugs or problems, please let me know.
