How to add data into Firestore Swift by tapping on a cell - swift

Question

I have more restaurants , each have diferent food.Look here
This is how im retrieving data from the Firestore. In the previous controller I have a list of restaurants, each contains a list food.
struct Food {
var photoKeyRestaurant: String
var foodName: String
var foodDescription: String
var restaurantName: String
var priceFood: Int
}
class RestaurantViewController: UIViewController {
var restaurantName: String!
var food: [Food] = []
private let tableView: UITableView = {
let table = UITableView()
return table
}()
func getDatabaseRecords() {
let db = Firestore.firestore()
// Empty the array
food = []
db.collection("RestaurantViewController").whereField("restaurantName", isEqualTo: restaurantName).getDocuments { (snapshot, error) in
if let error = error {
print(error)
return
} else {
for document in snapshot!.documents {
let data = document.data()
let newEntry = Food(photoKeyRestaurant: data["photoKeyRestaurant"] as! String, foodName: data["foodName"] as! String, foodDescription: data["foodDescription"] as! String, restaurantName: data["restaurantName"] as! String , priceFood: data["priceLabel"] as! Int
)
self.food.append(newEntry)
}
}
DispatchQueue.main.async {
// self.datas = self.filteredData
self.tableView.reloadData()
}
}
}
How can I add the data of the selected cell by pressing on + to Firestore in this function ?
I'vrea create a protocol in my FoodTableViewCell , and I've called it in the RestaurantViewController.
func diddTapButtonCell(_ cell: FoodTableViewCell) {
let db = Firestore.firestore()
db.collection("cart").addDocument.(data: foodName) { (err) in
}
Edited: Added Table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return food.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "FoodTableViewCell", for: indexPath) as! FoodTableViewCell
cell.delegate = self
let mancare = food[indexPath.row]
let storageRef = Storage.storage().reference()
let photoRef = storageRef.child(mancare.photoKeyRestaurant)
cell.foodImage.sd_setImage(with: photoRef)
cell.descriptionLabel.text = mancare.foodDescription
cell.foodNameLabel.text = mancare.foodName
cell.priceLabel.text = "\(mancare.priceFood) lei"
//Fac ca imaginea sa fie cerc - start
cell.foodImage.layer.borderWidth = 1
cell.foodImage.layer.masksToBounds = false
cell.foodImage.layer.borderColor = UIColor.black.cgColor
cell.foodImage.layer.cornerRadius = cell.foodImage.frame.height/2
cell.foodImage.clipsToBounds = true
//Fac ca imaginea sa fie cerc - finish
return cell
}
This is my tableview cell code
protocol CustomCellDelegate {
func diddTapButtonCell (_ cell: FoodTableViewCell)
}
class FoodTableViewCell: UITableViewCell {
var delegate: CustomCellDelegate?
#IBOutlet weak var foodImage: UIImageView!
#IBOutlet weak var foodNameLabel: UILabel!
#IBOutlet weak var descriptionLabel: UILabel!
#IBOutlet weak var priceLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
#IBAction func addToCart(_ sender: Any) {
delegate?.diddTapButtonCell(self)
}
}

https://firebase.google.com/docs/firestore/manage-data/add-data
And here is an example from one of my projects for adding data to firestore.
func updateDocument(rootCollection : String, doc: String, newValueDict: [String : Any], completion:#escaping (Bool) -> Void = {_ in }) {
let db = Firestore.firestore()
db.collection(rootCollection).document(doc).setData(newValueDict, merge: true){ err in
if let err = err {
print("Error writing document: \(err)")
completion(false)
}else{
completion(true)
}
}
}
