I totally did not expect to hear him mention Swift,(reply>), Plus Swift is now open source.,(reply>), Sub that is not true, swift 5.3 was just released and windows will be officially supported in the comming weeks.,(reply>), I'm not sure what Jeremy is thinking. Swift doesn't support Windows and probably never will; I'm not even sure how good the Linux support is. He said it himself at the end: Apple doesn't care. I think Swift is just an awful choice especially considering FastAI's goal of making AI more accessible. Accessibility is the complete opposite of what Apple stands for.
