Mea culpa. Reworded.

Careful, folks. S4TF is pretty much dead on arrival. It was pushed aggressively by Chris Lattner (for obvious reasons) but he left Google a while ago and since then most internal users lost interest. There's nothing in Swift that's inherently suitable for ML and building the ecosystem is a ton of work; without all the political pushing, it went nowhere and is close to a "semi-abandoned research project" phase.
