TableView displaying same array filtered elements even though array elements not filtered

Question

enter image description here I have 2 buttons and two array list items which shows fruit names and color of the fruit. I implemented search functionality to search fruit and color. The issue here is

1. Tap on 1st button shows fruit names in a tableview.
2. Filtered a fruit with name. It retrieves a fruit back
3. Now tap on outside of the tableview. It dismisses the tableview
4. Tap on second button fruit color.

Issue arrises. It showing first array elements with search keyword same I entered in the earlier search. Here is my code and screen shots for reference. Where I need to modify the code. Any help is appreciated.

import UIKit

class Cell : UITableViewCell {
}

class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchBarDelegate{
    
    @IBOutlet weak var selectFruit: UIButton! {
        didSet {
            selectFruit.layer.cornerRadius = 5
        }
    }
    @IBOutlet var selectColor: UIButton! {
        didSet {
            selectColor.layer.cornerRadius = 5

Answer 1

try this one

lazy var searchBar:UISearchBar = UISearchBar()

in viewDidLoad

searchBar.delegate = self

and call this function

    func searchBarShouldEndEditing(_ searchBar: UISearchBar) -> Bool {
    searchBar.text = ""
    return true
}
