Their justification for picking Swift over Julia rings a bit false, unless one reduces it to "we're familiar with Swift, and that's why".
They can't argue for Swift over Julia due to community size, given that Julia is far more portable, and more familiar to users in the scientific ___domain. 'Similarity of syntax to Python' is another very subjective 'advantage' of Swift: Later in the same document they mention "mainstream syntax" - that is, Swift having a different syntax from python - as an advantage.
I wonder whether they just decided on the language in advance, which is totally fine, but we could do without the unconvincing self-justification.
Julia may be portable but it doesn't run well at all on smaller embedded devices like a Pi or Nano for example and its compiler will be an issue on most mobile devices outside of terminal emulators.
