Do you also pronounce every abbreviation? Do you say "International Business Machines" instead of "IBM"? How about "Répondez s'il vous plaît" vs "RSVP". "As soon as possible" or "ASAP". Ever use a contraction? How about a keyboard shortcut?

I certainly agree it's potentially more readable at first. I'm not yet convinced, without actual data, that anyone, given a month or so experience with a given and common API wouldn't be more productive with shorter names up to a point. I would be good to get that data. Maybe I'd be better off with

    a = Math.numberFromAddtionOf2Numbers(c, d)
    e = Math.numberFromDivisionOf2Numbers(numerator: b, denominator, c);

vs

    a = c + b;
    e = b / c;

which is best

    s = str.stringByReplacingOccurrencesOfString(" ", withString: "", options: .LiteralSearch, range: nil)
    s = str.replace(" ", "");
    s = str.r(" ", "");

I'd do

    s = str.replacing(" ", with: " ")

which seems to go along well with the "sorted" and "appending" mentioned in the new API design guidelines:

https://swift.org/documentation/api-design-guidelines/#be-gr...

This is a bit more verbose if you need to chain a lot of replacements... but chances are you shouldn't be doing that in the first place! Instead there should be a version that takes a dictionary, like

    str.replacing(["<": "&lt;", "&": "&amp;"])

This is better because most of the time you don't actually want characters produced by earlier replacements to match later ones, and it can be faster for large strings.
