But let's delve in. Why is it impossible to analyze a language from a programming language theory perspective without having used it? Obviously having used it will give a fuller perspective, but I don't see what you think is so deficient about the extensive documentation Apple has put out that it's impossible to comment from a theoretical standpoint on that basis.

To put it another way, I think you should drop the snark. If you have an actual problem with the critique or with the Swift documentation, you can bring it up. A snarky dismissal like "Question; why post this then?" does not add anything.
