Swift 2 version of @akashivskyy's extension,

 extension String {
     init(htmlEncodedString: String) {
         if let encodedData = htmlEncodedString.dataUsingEncoding(NSUTF8StringEncoding){
             let attributedOptions : [String: AnyObject] = [
            NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
            NSCharacterEncodingDocumentAttribute: NSUTF8StringEncoding
        ]

             do{
                 if let attributedString:NSAttributedString = try NSAttributedString(data: encodedData, options: attributedOptions, documentAttributes: nil){
                     self.init(attributedString.string)
                 }else{
                     print("error")
                     self.init(htmlEncodedString)     //Returning actual string if there is an error
                 }
             }catch{
                 print("error: \(error)")
                 self.init(htmlEncodedString)     //Returning actual string if there is an error
             }

         }else{
             self.init(htmlEncodedString)     //Returning actual string if there is an error
         }
     }
 }
