Unggah data formulir Eureka ke firebase

Saya memiliki profil pengguna yang merupakan tampilan formulir Eureka. Di ruang ini, pengguna dapat memperbarui profilnya. Jika pengguna mengklik 'Simpan', fungsi ini akan dipanggil.

    func saveProfileSettings(){

    let userID = user?.uid
    let formatter = DateFormatter()
    formatter.dateFormat = "yyyy-MM-dd"

    let PROFILE_DISPLAY_NAME_REF: NameRow? = form.rowBy(tag: Constants.PROFILE_DISPLAY_NAME)
    let PROFILE_DISPLAY_NAME = PROFILE_DISPLAY_NAME_REF?.value

    let PROFILE_EMAIL_REF: EmailRow? = form.rowBy(tag: Constants.PROFILE_EMAIL)
    let PROFILE_EMAIL = PROFILE_EMAIL_REF?.value

    let PROFILE_PHONENUMBER_REF: PhoneRow? = form.rowBy(tag: Constants.PROFILE_PHONENUMBER)
    let PROFILE_PHONENUMBER = PROFILE_PHONENUMBER_REF?.value

    let PROFILE_BIRTH_AGE_REF: DateRow? = form.rowBy(tag: Constants.PROFILE_BIRTH_AGE)
    let PROFILE_BIRTH_AGE_CONVERT = PROFILE_BIRTH_AGE_REF?.value
    let PROFILE_BIRTH_AGE = formatter.string(from: PROFILE_BIRTH_AGE_CONVERT!)
    let PROFILE_BIRTH_AGE_String = String(PROFILE_BIRTH_AGE)

    let PROFILE_GENDER_REF: SegmentedRow<String>! = form.rowBy(tag: Constants.PROFILE_GENDER)
    let PROFILE_GENDER = PROFILE_GENDER_REF.value

    let PROFILE_GENDER_INTEREST_REF: SegmentedRow<String>! = form.rowBy(tag: Constants.PROFILE_GENDER_INTEREST)
    let PROFILE_GENDER_INTEREST = PROFILE_GENDER_INTEREST_REF.value

    let uploadPath = databaseRef.child("profiles").child(userID!)

    let dataBlock = ["\(Constants.PROFILE_DISPLAY_NAME)": PROFILE_DISPLAY_NAME!, "\(Constants.PROFILE_EMAIL)": PROFILE_EMAIL!, "\(Constants.PROFILE_PHONENUMBER)": PROFILE_PHONENUMBER!, "\(Constants.PROFILE_BIRTH_AGE)": PROFILE_BIRTH_AGE_String!, "\(Constants.PROFILE_GENDER)": PROFILE_GENDER!, "\(Constants.PROFILE_GENDER_INTEREST)": PROFILE_GENDER_INTEREST!]

    print("DataBlock \(dataBlock)")

    uploadPath.setValue(dataBlock) { (error, datebaseRef) in
        if error != nil{
            print("Error Occured")
        }
        print("Profile Updated!")
    }



}

Tugas fungsi ini adalah menarik semua data dari formulir, memasukkannya ke dalam array, lalu mengunggahnya ke firebase. Jika pengguna mengklik simpan dan tidak memperbarui informasi apa pun semuanya baik-baik saja namun jika mereka mengedit profilnya dan mengklik simpan, hal itu menyebabkan kesalahan. Lihat di bawah.

Jika Anda ingin melihat kode apa untuk membuat formulir, ada di 'viewDidLoad' saya

override func viewDidLoad() {
    super.viewDidLoad()

    self.startAnimating(Constants.animationSize, message: "Finding Your Profile", type: .ballZigZag)

    //findImageURL()


    //START

    let userID = user?.uid
    print("Logged in user: \(userID!)")


    databaseRef.child("profiles").child(userID!).observe(.value, with: { (snapshot) in


        let data = snapshot.value as? NSDictionary

        let PROFILE_DISPLAY_NAME = data?[Constants.PROFILE_DISPLAY_NAME] as? String
        let PROFILE_UID = data?[Constants.PROFILE_UID] as? String
        let PROFILE_IMAGE = data?[Constants.PROFILE_IMAGE] as? String
        let PROFILE_EMAIL = data?[Constants.PROFILE_EMAIL] as? String
        let PROFILE_PHONENUMBER = data?[Constants.PROFILE_PHONENUMBER] as? String
        let PROFILE_GENDER = data?[Constants.PROFILE_GENDER] as? String
        let PROFILE_GENDER_INTEREST = data?[Constants.PROFILE_GENDER_INTEREST] as? String
        let PROFILE_BIRTH_AGE = data?[Constants.PROFILE_BIRTH_AGE] as? String
        let PROFILE_LATITUDE = data?[Constants.PROFILE_LATITUDE] as? String
        let PROFILE_lONGITUDE = data?[Constants.PROFILE_lONGITUDE] as? String

        self.form +++ Section("Personal Information")

            <<< NameRow(){ row in

                row.title = "Name"
                row.placeholder = "Enter Name"
                row.value = PROFILE_DISPLAY_NAME

            }

            <<< DateRow(){ row in

                //Convert 'PROFILE_BIRTH_AGE' string to NSDATE
                let date = NSDate()
                let dateFormatter = DateFormatter()
                dateFormatter.dateFormat = "yyyy-MM-dd"
                let formattedDate = dateFormatter.date(from: PROFILE_BIRTH_AGE!)

                row.value = formattedDate

            }



            +++ Section("Dating Settings")

            <<< SegmentedRow <String> (){ row in

            }




        self.stopAnimating()


    })

    //STOP


}

Saya tidak tahu apa yang menyebabkan kesalahan ini terjadi!
