Great news. Congratulations to both new member of Swift core team.
Talking about machine learning, I hope the Swift core team would like to give a little bit more attention to the Swift for TensorFlow team. They have some ideas that could be considered to be part of Swift language feature regarding machine learning. For example, differentiable programming.
How about Apple's Combine and SwiftUI frameworks? Is it possible to make them work on other platforms as well?
