Swift 4.2 (2018) introduced a cross platform random number API.

    (0..<10).randomElement()

Yet they didn't bother to update the example on the introduction to Swift.

There are plenty of other examples I can look for, like file handling.

[slavapestov]

File handling can be done using Foundation, which I believe has API parity between Darwin and Linux at least.

I think the point of the example was to demonstrate importing platform-specific modules, not random number generation per se. But you're right, it should probably be updated to do something else.

There are widely popular FOSS languages with much much less documentation...

Such as?

Golang has terser and worse documentation than Swift, for one...
