I agree. As a user of a German keyboard, "\" is written as Alt-Shift-7 (there isn't even a label on the keyboard, you just have to know this. The "7" key says "7" and "/" - I'm talking about the German Mac Keyboard, the standalone version of the Mac Mini and the Notebook Version of Macbook Air/Pro are the same in this regard.), and "$" is written as Shift-4. "$" is used in languages were "$" is used as a sigil for variables. It makes sense there to allow these variables directly in some strings. But not so in Swift. What I like about "\" is that it is a compatible extension to string literals, as much as possible. Strings that were valid and sensible before are still valid and sensible and mean the same thing. You can copy&paste a C string literal into Swift, and it will have the same meaning, because C strings do not contain `\(`.
I'm already used to using Alt- and Alt-Shift combinations anyway, they are just needed everywhere. Can use them for „German typographical quotes“ (Alt-^, Alt-2), “English typographical quotes” (Alt-Shift-^, Alt-Shift-2), 2 ≤ 4 comparisons, etc. E.g. the "" are Alt-5 and Alt-6.
That said, there is a programming co-worker of mine that uses an English keyboard, because he says it's easier to write code there. That's actually something that many non-English programmers do right now.
