How to convert Data to a String

Paul Hudson       @twostraws

If you know an instance of Data contains a String and you want to convert it, you should use the String(decoding:as:) initializer, like this:

String(decoding: data, as: UTF8.self)

Note: you do need to know which format is used to store the string, but UTF-8 is usually the best to go with.
