TableView - “Thread 1: Fatal error: Index out of range in Swift” - swift

Question

I'm pulling data from the database, I'm having no problems with data, but I'm having trouble transferring this data to the text in the Cell. I think I'm having a problem with the numberOfRowsInSection count. I want to add as much data as the sum of the two data, but I'm having trouble this way.
class ChatRoomViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var bilgiCevap = [String]()
var bilgiKullanıcı = [String]()
override func viewDidLoad() {
super.viewDidLoad()
FCevap()
chatTableView.delegate = self
chatTableView.dataSource = self
func FCevap(){
let client = SQLClient.sharedInstance()!
client.connect("...", username: "...", password: "...", database: "...") { success in
client.execute("SELECT ... FROM ... WHERE . LIKE '\(self.form_no)' AND ... LIKE '0'", completion: { (_ results: ([Any]?)) in
for table in results as! [[[String:AnyObject]]] {
for row in table {
for (_, value) in row {
if let intVal = value as? String {
self.bilgiKullanıcı.append(String(intVal))
}} }}
DispatchQueue.main.async {
self.Kullanici()
self.chatTableView.reloadData()}
client.disconnect() }) }
}
func Kullanıcı(){
let client = SQLClient.sharedInstance()!
client.connect("...", username: "...", password: "...", database: "...") { success in
client.execute("SELECT ... FROM ... WHERE ... LIKE '\(self.form_no)' AND ... LIKE '1'", completion: { (_ results: ([Any]?)) in
for table in results as! [[[String:AnyObject]]] {
for row in table {
for (_, value) in row {
if let intVal = value as? String {
self.bilgiCevap.append(String(intVal))
}} }}
DispatchQueue.main.async {self.chatTableView.reloadData()}
client.disconnect() }) }
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = chatTableView.dequeueReusableCell(withIdentifier: "chatCell") as! ChatCell
let messageGıden = self.bilgiKullanıcı[indexPath.row]
cell.chatTextView.text = messageGıden
cell.usernameLabel.text = "..."
cell.setBubbleType(type: .incoming)
let messageGelen = self.bilgiCevap[indexPath.row]
cell.chatTextView2.text = messageGelen
cell.userNameLabel2.text = "Kullanıcı"
cell.setBubbleType2(type: .outgoing)
return cell
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return bilgiCevap.count + bilgiKullanici.count
}
}

Answer 1

if you have data sources you need to take two Sections in number of section delegate.
func numberOfSections(in tableView: UITableView) -> Int {
return 2
}
And in numberOfRows section
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return dataSource1.count
} else {
return dataSource2.count
}
}
and then inside cellFor rowAt delegate
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let data = dataSource1[indexPath.row]
} else {
let data = dataSource2[indexPath.row]
}
}
