I’m wondering if converting Planck’s Objective C to Swift would be a good path to Linux.

It would certainly make it more pleasant to work with :)

But I guess gcc can handle Objective C?

Maybe some of the smaller files can be converted first.

I was thinking of the possibility of using the open-sourced Swift compiler and especially its runtime classes, thinking it must be very close to what a lot of Planck currently makes use of in the Objective-C runtime.

I suppose GCC would lead to Windows, where Swift on Windows isn't a thing yet. (But Windows will be able to perhaps run Linux binaries soon.)
