When running genstrings against a Swift file, if there are any NSLocalizedString calls that use more than the trivial case of "value" and "comment" parameters, genstrings errors out.

Steps to Reproduce:
1. Create a new Xcode Project
2. Create some localized String with more than 2 parameters in a .swift File, e.g.

let string NSLocalizedString("key", table:"table", value: "value", comment: "comment")
3. Run genstrings

Expected Results:
Genstring should generate the file `table.strings` with an entry

/* comment */
"key" = "value"

Actual Results:
Genstrings creates an error: 

Bad entry in file ./Enduser/Controllers/ScratchFieldViewController.swift (line = 18): Argument is not a literal string.
