The biggest drawbacks of Swift are the legacy relationships it has to the Apple ecosystem. Yet swift is open source, and Apple and the community can fork it if they so choose. This is great news for me personally as an iOS developer and an ML noob who doesn't want to write Python. I can't comment on Julia because I have no experience with it, but I applaud the efforts to build the Swift ecosystem to challenge Python. I think a lot of the criticisms so far are that it's early days for Swift in ML, and that's one point the author is emphasizing.
