Swift Alamofire JSON Parsing

I'm making JSON parsing with Alamofire. I can get data from web service. I want to set label. I can print any data with "print()" function. But i can not set to label. Please help me.

My code is here.

        Alamofire.request(.GET, "url").validate().responseJSON { response in
        switch response.result {
        case .Success:
            if let value = response.result.value {
                let jsonObject = JSON(value)

                // this row is working.
                print(jsonObject["Title"].stringValue)
                // i can not print to label here
                if let titleValue = jsonObject["Title"].string {
                    self.newsTitleLabel.text = titleValue
                }


            }
        case .Failure(let error):
            print(error)
        }
    }

//print result:
Bolu Dağı'nda bayram tatili yoğunluğu
//if blok:
fatal error: unexpectedly found nil while unwrapping an Optional value
Solution

  • You mean the crash is on the line self.newsTitleLabel.text = titleValue, right? Make sure that your newsTitleLabel does exists either it is IBOutlet/variable.
