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&         


        

Answer 1

extension String{
    func decodeEnt() -> String{
        let encodedData = self.dataUsingEncoding(NSUTF8StringEncoding)!
        let attributedOptions : [String: AnyObject] = [
            NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
            NSCharacterEncodingDocumentAttribute: NSUTF8StringEncoding
        ]
        let attributedString = NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil, error: nil)!

        return attributedString.string
    }
}

let encodedString = "The Weeknd ‘King Of The Fall’"

let foo = encodedString.decodeEnt() /* The Weeknd ‘King Of The Fall’ */
