There are a lot of questions and answers belonging how to read the contents of a directory. Unfortunatly none of them I get to work with Swift 3.0. Is there any update, which is running right now?
(Most of them get errors by the compiler and if I correct everything the way the compiler sugguested, I get a runtime error later on!) :-(
Reference to linked solution: This does not show any sub folder files like "while let url = enumerator.nextObject() as? URL" did. Is the headline misleading or do I need different function or additional parameters?
