How to put data from array into label Swift 3 - ios

Question

Im really new to Swift, the question is how can I represent values from array in label.
I want a TableView with cells dynamically represent values from array into the labels which will be created in tableView rows.
import UIKit
import Foundation
class TableViewMarketItemsViewCell: UITableViewController {
var fruits = ["Avocado", "Apricot", "Pomegranate", "Quince"]
var PriceArray = ["1000 тг.","4000 тг.","3000 тг.","2000 тг."]
var categoryArray = ["Green category","Maroon category","Red category","Yellow category"]
// MARK: - UITableViewDataSource
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return fruits.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "LabelCell", for: indexPath) as! TableViewCell
let fruitName = fruits[indexPath.row]
cell.productTitle.text = fruitName
cell.productImage.image = UIImage(named: fruitName)
return cell
}
}
Thnx in advance

For inserting data into UITableViewcell use below code:
import UIKit
class ViewController: UIViewController,UITableViewDataSource {
#IBOutlet var tableView: UITableView!
var dataArray:NSArray!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tableView.dataSource = self
dataArray = NSArray(objects: "a","b","c")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = dataArray.object(at: indexPath.row) as? String
return cell
}
}
tableView is outlet of UItableView.

You can populate an UITableView from an array like below:
(assuming that your array has a list of string values):
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return array.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Creating the tableView cell
let tableViewCell = tableView.dequeueReusableCell(withIdentifier: "tableViewCell", for: indexPath) as! UITableViewCell
//Assigning values
tableViewCell.lblName?.text = array.object(at: indexPath.row) as? String
return tableViewCell
}
In this way you can show the value from your array to the label in your tableView.
