How do I decode HTML entities in Swift?

Question

I am pulling a JSON file from a site and one of the strings received is:

The Weeknd ‘King Of The Fall&

This would be my approach. You could add the entities dictionary from https://gist.github.com/mwaterfall/25b4a6a06dc3309d9555 Michael Waterfall mentions.

extension String {
    func htmlDecoded()->String {

        guard (self != "") else { return self }

        var newStr = self

        let entities = [
            """    : "\"",
            "&"     : "&",
            "'"    : "'",
            "<"      : "<",
            ">"      : ">",
        ]

        for (name,value) in entities {
            newStr = newStr.stringByReplacingOccurrencesOfString(name, withString: value)
        }
        return newStr
    }
}

Examples used:

let encoded = "this is so "good""
let decoded = encoded.htmlDecoded() // "this is so "good""

OR

let encoded = "this is so "good"".htmlDecoded() // "this is so "good""
