Weather Swift Preferences - swift

Question

I'm currently working on an app with xCode, i'm new to iOS. My weather format is currently submitting "Celcius" & "Fahrenheit" to my database instead of sending C or F. I have try several thing but it seem to look like it also change my display text to C or F. I want to keep the display text to Fehrenheit & Celcius. Here's my code:
import UIKit
import FirebaseAuth
import FirebaseDatabase
class PreferencesVC: UIViewController, UITextFieldDelegate,
UIPickerViewDataSource, UIPickerViewDelegate {
#IBOutlet weak var setTimeFormat: UITextField!
#IBOutlet weak var setUnitFormat: UITextField!
#IBOutlet weak var setLanguage: UITextField!
var timePicker = UIPickerView()
var unitPicker = UIPickerView()
var languagePicker = UIPickerView()
var timeData: [String] = [String]()
var unitData: [String] = [String]()
var langugageData: [String] = [String]()
var preferenceHandle: DatabaseHandle!

Remove this row in submitButtonPressed since it overrides what has been set just before
userPreferences["UserTempFormat"] = unitFormat
