can't reload Array<any>? data from firebase to Table View swift - arrays

Question

my Data Model :
class KeyModell {
var UserID : String?
var key : Array<Any>?
init(UserIDString : String , keyString : Array<Any>? ) {
UserID = UserIDString
key = keyString
}
}
My ViewContoller :
class ViewController: UIViewController {
var userID = ""
var keyContiner = [KeyModell]()
#IBOutlet weak var tableViewOutLet: UITableView!
#IBOutlet weak var textFeildOUtLet: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
FetchUsers(userID: userID) { (user) in
// print("userID His Profile \(user.id)")
}
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(true)
fetchKey()
tableViewOutLet.reloadData()
}
#objc func fetchKey () {
Database.database().reference().child("AdminKeys").observeSingleEvent(of: .value) { (snapshot) in
// print(snapshot.value)
for child in snapshot.children.allObjects as! [DataSnapshot] {
if let dict = child.value as? [String : Any] {
// print(dict)
let userID = dict["UserID"] as! String
if let keyID = dict["key"] as! Array<Any>? {
let key = KeyModell.init(UserIDString: userID, keyString: keyID)
self.keyContiner.append(key)
self.tableViewOutLet.reloadData()
}
self.tableViewOutLet.reloadData()
}
}
}
func FetchUsers (userID : String , Compation : #escaping (UserModel)->Void) {
Database.database().reference().child("Users").child(userID).observe(.childAdded) { (snapshot) in
if let dic = snapshot.value as? [String : Any] {
let user = UserModel.TransferUserModel(dic: dic, key: snapshot.key)
Compation(user)
}
}
}
#IBAction func saveKeybtn(_ sender: Any) {
let keyString : String = textFeildOUtLet.text!
let keys = keyString.components(separatedBy: ",")
let ref : DatabaseReference!
ref = Database.database().reference()
let AdminKeysREF = ref.child("AdminKeys")
let newKeysPostID = AdminKeysREF.childByAutoId()
guard let userID = Auth.auth().currentUser else {return}
let userKeyId = userID.uid
newKeysPostID.setValue(["UserID": userKeyId , "key" : keys] )
}
extension ViewController : UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return keyContiner.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) as! KeyCell
return cell
}
My Cell :
class KeyCell: UITableViewCell {
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
#IBOutlet weak var keyOUtLet: UILabel!
var key : KeyModell?{
didSet {
upDatekey()
}
}
func upDatekey() {
keyOUtLet.text = key?.key
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
My database :
when i print(cell.key) it give me result :
the problem was when i try to set lable to key mode like this :
func upDatekey() {
keyOUtLet.text = key?.key
}
it give me error "Cannot assign value of type '[Any]?' to type 'String?'"
as my database key value are Array so i set it like this :
var key : Array<Any>?
i think the problem from here i can't figuer it out

Answer 1

I solve the issue ,
my firebase database node is an Int array , so i have to cast my object as [String] than i loop thrught the arrya to extract the kyes
if let key = dict["key"] as? [String] {
for keys in key {
print(keys)
}
than i load it to table view . it work fine .
