CwlDemangle
A translation (line-by-line in many cases) of Swift's Demangler.cpp into Swift.
License note
I usually place my code under an ISC-style license but since this project is derived from the Swift project, it is covered by that project's Apache License 2.0 with runtime library exception.
Usage
Parse a String containing a mangled Swift symbol with the parseMangledSwiftSymbol function:
let swiftSymbol = try parseMangledSwiftSymbol(input)
Print the symbol to a string with description (to get the .default printing options) or use the print(using:) function, e.g.:
let result = swiftSymbol.print(using:
SymbolPrintOptions.default.union(.synthesizeSugarOnTypes))
