Swift 3 version of @akashivskyy's extension,

extension String {
    init(htmlEncodedString: String) {
        self.init()
        guard let encodedData = htmlEncodedString.data(using: .utf8) else {
            self = htmlEncodedString
            return
        }

        let attributedOptions: [String : Any] = [
            NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
            NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue
        ]

        do {
            let attributedString = try NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil)
            self = attributedString.string
        } catch {
            print("Error: \(error)")
            self = htmlEncodedString
        }
    }
}
