Swift: How to pass data from selected cell using Firebase? - ios

Question

I want to pass data from selected cell to ViewController.
With my code just pass data from the last cell no matter which cell is selected.
' func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return guestsList.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "guestCell", for: indexPath) as! GuestTableViewCell
let guest: GuestModel
guest = guestsList[indexPath.row]
cell.guestNameLabel.text = guest.guestName
cell.attendingLabel.text = guest.attendingStatus
cell.menuLabel.text = guest.menuStatus
cell.ageLabel.text = guest.ageStatus
cell.tableLabel.text = guest.tableNo
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
performSegue(withIdentifier: "toGuestDetails", sender: self
)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "toGuestDetails"{
if let indexPath = guestsTableView.indexPathForSelectedRow {
let destinationVC = segue.destination as! GuestDetailsViewController
destinationVC.guestDetail = [guestsList[indexPath.row]]
}
}
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete {
let guest = guestsList[indexPath.row]
self.guestsList.remove(at: indexPath.row)
self.guestsTableView.reloadData()
self.deleteGuest(id: guest.id!)
}
}
func deleteGuest(id: String){
refGuests.child(id).setValue(nil)
self.guestsTableView.reloadData()
}'
And here is my ViewController with details:
' #IBOutlet var nameLabel: UILabel!
#IBOutlet var emailLabel: UILabel!
#IBOutlet var phoneNoLabel: UILabel!
var ref: DatabaseReference!
let uid = Auth.auth().currentUser?.uid
var guestDetail = [GuestModel]()
override func viewDidLoad() {
super.viewDidLoad()
showGuestDetails()
}
func showGuestDetails(){
ref = Database.database().reference().child("userInfo").child(uid!).child("guests")
ref.queryOrderedByKey().observe(.value) { (snapshot) in
if snapshot.childrenCount>0{
self.guestDetail.removeAll()
for guests in snapshot.children.allObjects as![DataSnapshot]{
let guestObject = guests.value as? [String: AnyObject]
let guestName = guestObject?["guestName"]
let guestFamilyName = guestObject?["guestFamilyName"]
let phone = guestObject?["guestPhoneNumber"]
let email = guestObject?["guestEmail"]
let guestDetails = GuestModel(guestName: guestName as? String, guestFamilyName: (guestFamilyName as? String)!, guestPhoneNumber: phone as? String, guestEmail: email as? String)
let fullName = guestDetails.guestName! + " " + guestDetails.guestFamilyName!
self.nameLabel.text = fullName
self.emailLabel.text = guestDetails.guestEmail
self.phoneNoLabel.text = guestDetails.guestPhoneNumber
self.guestDetail.append(guestDetails)
}
}
}
}
