    Swift 4 Version

    extension String {
    
        init(htmlEncodedString: String) {
            self.init()
            guard let encodedData = htmlEncodedString.data(using: .utf8) else {
                self = htmlEncodedString
                return
            }
    
            let attributedOptions: [NSAttributedString.DocumentReadingOptionKey : Any] = [
                .documentType: NSAttributedString.DocumentType.html,
                .characterEncoding: String.Encoding.utf8.rawValue
            ]
    
            do {
                let attributedString = try NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil)
                self = attributedString.string
            } 
            catch {
                print("Error: \(error)")
                self = htmlEncodedString
            }
        }
    }
