Looks like a good start! You might also want to handle the $(xxx) form of interpolation (which can get pretty tricky I imagine), as well as all of the \ escapes, such as \n, \x, \u, \U, etc.
I'd like just this, but with the Swift syntax for interpolation, i.e. \(xxx), which doesn't have the problem of causing a frequently used character ($) to have to be quoted (\$) where it wouldn't be in C/C++/Java/etc. (or for LaTex strings).
