Assuming you have to do a lot of string processing (for NLP). Do you have any "shortcut" to do that in Swift? The API is thoughtful, but tedious to type, comparing to Python. It would be great if we have some semi-official "shortcut" libraries just for string processing (The recent RegEx literal is a welcome addition, but not enough).

That's a very gentle way to describe the agony of string processing in Swift :-).

We have written a few shortcut libraries ourselves, but we actually don't end up writing a great deal of string processing code in practice because most of our operations are expressed in a higher level query language that gets compiled down to lower-level operator implementations (which only get written once).

The vast majority of our code (maybe like a lot of systems?) ends up being more about the management of the broader data & processing environment that coordinates everything.
