I am currently building a user creation mechanism where I have 8 UI switches to determine if someone has a food allergy or not. I have created an @IBOutlet for each switch and now have them contained in the document. I'm having no issue adding text fields:
let db = Firestore.firestore()
db.collection("users").addDocument(data: ["firstname":firstname, "lastname":lastname, "username":username, ]
What I'd like to do is extend that syntax to add the status of the 8 UISwitch's on user creation.
New to Firebase and app development, but tried Googling everything I could think of. Thanks in advance for your help!
UPDATE OK, so I must still be doing something wrong here, but I think I'm getting close:

class SignUpViewController: UIViewController {
@IBOutlet weak var firstNameTextField: UITextField!
@IBOutlet weak var lastNameTextField: UITextField!
@IBOutlet weak var usernameTextField: UITextField!

@IBOutlet weak var passwordTextField: UITextField!
@IBOutlet weak var milkSwitch: UISwitch!
@IBOutlet weak var peanutSwitch: UISwitch!
@IBOutlet weak var wheatSwitch: UISwitch!
@IBOutlet weak var treeNutSwitch: UISwitch!
@IBOutlet weak var fishSwitch: UISwitch!
@IBOutlet weak var shellFishSwitch: UISwitch!
@IBOutlet weak var eggSwitch: UISwitch!
@IBOutlet weak var soySwitch: UISwitch!
@IBOutlet weak var addAFamilyButton: UIButton!
@IBOutlet weak var signUpButton: UIButton!
@IBOutlet weak var errorLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setUpElements()
}
func setUpElements (){
errorLabel.alpha = 0
}
func showError(_ message:String) {
errorLabel.text = message
errorLabel.alpha = 1
}
//Check the fields and validate that data is correct.
func validateFields() -> String? {
//Check that all fields are filled in
if firstNameTextField.text?.trimmingCharacters(in: .whitespacesAndNewlines) == "" ||
lastNameTextField.text?.trimmingCharacters(in: .whitespacesAndNewlines) == "" ||
usernameTextField.text?.trimmingCharacters(in: .whitespacesAndNewlines) == "" ||
emailTextField.text?.trimmingCharacters(in: .whitespacesAndNewlines) == "" ||
passwordTextField.text?.trimmingCharacters(in: .whitespacesAndNewlines) == "" {
return "Please fill in all fields."
}
//Check if password is secure
let cleanedPassword = passwordTextField.text!.trimmingCharacters(in: .whitespacesAndNewlines)
if Utilities.isPasswordValid(cleanedPassword) == false {
// Password isn't secure enough
return "Please make sure your password is at least 8 characters, contains a special character and a number"
}
return nil
}

let egg = eggSwitch
let soy = soySwitch
// Create the user
Auth.auth().createUser(withEmail: email, password: password) { (result, err) in
// Check for errors
if err != nil {
//There was an error creating the user
self.showError("Error creating user")
}
else {
// User was created successfully
let db = Firestore.firestore()
db.collection("users").addDocument(data: ["firstname":firstname, "lastname":lastname, "username":username, "uid": result!.user.uid, "milk":milkSwitch.isOn, "peanut":peanutSwitch.isOn, "wheat":wheatSwitch.isOn, "treenut":treeNutSwitch.isOn, "fish":fishSwitch.isOn, "shellfish":shellFishSwitch.isOn, "egg":eggSwitch.isOn, "soy":soySwitch.isOn ]) { (error) in
if error != nil {
//Show error message
self.showError("Your allergies have not been saved. Please login to your account")

You can use isOn to get the status of a UISwitch
let peanutAllergySwitch = UISwitch()
let db = Firestore.firestore()
let data = [
"firstname":firstname,
"lastname":lastname,
"username":username,
"allergicToPeanuts": peanutAllergySwitch.isOn
]
db.collection("users").addDocument(data: data)
