If you have time data in the form of a string format and want to change it to the second form to make a stopwatch, then you can follow this method below.

  let greeting = "12:14:57"
        let words = greeting.split(separator: ":")
        
        let toBe = Int(words[0])
        let toBe1 = Int(words[1])
        let toBe2 = Int(words[2])
        
        let be = toBe! * 60 * 60
        let be1 = toBe1! * 60
        let be2 = toBe2! + be1 + be
        
        print("\(words[0]), \(words[1]), \(words[2])")
        print("hasilnya: \(be2)")

I want to build tableview in different sections, contents of the section are:

section 1 = string array
section 2 = string array
section 3 = button

First, u must create expand and collapse table view. There are many ways to create the appearance of expanding TableView cells.  In the below code, we make the cell to be expanded .

After u create that you can follow this code bellow.

import UIKit

struct NewData {
    var isOpen: Bool = false
    var title: String = ""
    var data: [String] = []
    var data2: [String] = []
}

class ExpandExpertVC: UIViewController {
    @IBOutlet weak var tableExpand: UITableView!
    
     var dataPicker: [NewData] = []
    
    override func viewDidLoad() {
        super.viewDidLoad()
        setupComponent()
     
        var data: [NewData] = []
        
        data.append(NewData(isOpen: false, title: "First", data: ["Produk:", "Perusahaan:", "tipe:", "Aksesoris:", " Total:"], data2: ["", "", "", "", ""]))
        data.append(NewData(isOpen: false, title: "Second", data: ["Name:", "No:", "gender:"], data2: ["", "", ""]))
        data.append(NewData(isOpen: false, title: "Other", data: [""], data2: [""]))
        
        self.dataPicker = data
    }
    
    func setupComponent() {
        tableExpand.dataSource = self
        tableExpand.delegate = self
        tableExpand.rowHeight = UITableViewAutomaticDimension
        tableExpand.estimatedRowHeight = 40
        tableExpand.separatorInset = UIEdgeInsetsMake(0, UIScreen.main.bounds.width, 0, 0)
        tableExpand.register(UINib(nibName: "IsiTableViewCell", bundle: nil), forCellReuseIdentifier: "list")
        tableExpand.register(UINib(nibName: "TitleTableViewCell", bundle: nil), forCellReuseIdentifier: "tittle")
        tableExpand.register(UINib(nibName: "ButtonTableViewCell", bundle: nil), forCellReuseIdentifier: "button")
        
    }

}

extension ExpandExpertVC: UITableViewDataSource, UITableViewDelegate {
    func numberOfSections(in _: UITableView) -> Int {
        return dataPicker.count
    }
    
    func tableView(_: UITableView, numberOfRowsInSection section: Int) -> Int {
        if dataPicker[section].isOpen {
            return dataPicker[section].data.count + 1
        } else {
            return 1
        }
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        if indexPath.row == 0 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "tittle", for: indexPath) as! TitleTableViewCell
            cell.titleLabel.text = dataPicker[indexPath.section].title.uppercased()
            cell.separatorInset = UIEdgeInsetsMake(1, 1, 1, 1)
            
            return cell

       } else if indexPath.section == 2 && indexPath.row == 1 {
            let cell = tableView.dequeueReusableCell(withIdentifier: "button", for: indexPath) as! ButtonTableViewCell
            
            return cell
        } else {
            
            let cell = tableView.dequeueReusableCell(withIdentifier: "list", for: indexPath) as! IsiTableViewCell
            cell.isilabel.text = dataPicker[indexPath.section].data[indexPath.row - 1]
            cell.detailLabel.text = dataPicker[indexPath.section].data2[indexPath.row - 1]
            return cell
        }
    }
    
    func tableView(_: UITableView, didSelectRowAt indexPath: IndexPath) {
        if indexPath.row == 0 {
            if dataPicker[indexPath.section].isOpen {
                dataPicker[indexPath.section].isOpen = false
                let section = IndexSet(integer: indexPath.section)
                tableExpand.reloadSections(section, with: .fade)
                print("section \(section)")
                
               
            } else {
                dataPicker[indexPath.section].isOpen = true
                let section = IndexSet(integer: indexPath.section)
                tableExpand.reloadSections(section, with: .fade)
                print("section \(section)")
            }
            
        } else {
            print("CELL section: \(indexPath.section) - row: \(indexPath.row)")
        }
    }
    
}

if you want to know how to make some of the labels click, this is how I make it. use cocoapod SwiftyAttributes


pod 'SwiftyAttributes'


example:

"Hello World".withUnderlineColor(.red).withUnderlineStyle(.styleDouble)

https://github.com/eddiekaiger/SwiftyAttributes

Fullcode

import UIKit

import SwiftyAttributes



class SwiftAttributeVC: UIViewController {

    @IBOutlet weak var labelAttribute: UILabel!

    

    override func viewDidLoad() {

        super.viewDidLoad()

        

        let agreement = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. ".withFont(self.labelAttribute.font) + "Terms ".withTextColor(.blue).withFont(self.labelAttribute.font) +  "& ".withFont(self.labelAttribute.font) + " Conditions".withTextColor(.blue).withFont(self.labelAttribute.font)

        

        

        self.labelAttribute.attributedText = agreement

        let tapAction = UITapGestureRecognizer(target: self, action: #selector(self.tapLabel))

//        let tapAction2 = UITapGestureRecognizer(target: self, action: #selector(self.tapLabel2))

        self.labelAttribute.isUserInteractionEnabled = true

        self.labelAttribute.addGestureRecognizer(tapAction)

        

     

    }

    

    @objc func tapLabel(gesture: UITapGestureRecognizer) {

        print("test 1")

        

        let text = (labelAttribute.text)!

        let termsRange = (text as NSString).range(of: "Terms & Conditions")

    }



}

Using tags to track index paths is a common but very poor practice. It fails in any table view that allows rows to be deleted, inserted, or moved because remaining cells now have invalid tags unless the table view is fully reloaded using reloadData.

 func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! ATableViewCell
        cell.deleteButton.addTarget(self, action: #selector(nHapusTap(_:)), for: .touchUpInside)            

        return cell
    }

  @objc func nHapusTap(_ sender: UIButton) {
        let hitPoint = sender.convert(CGPoint.zero, to: tableView)
        if let indexPath = tableView.indexPathForRow(at: hitPoint) {

            self.dataArray.remove(at: indexPath.row)
            tableView.beginUpdates()
            tableView.deleteRows(at: [indexPath], with: .automatic)
            tableView.endUpdates()

        }

    }

Problem: i use kingfisher and can't reload image, how to fix it ?

solution :  if it was http or https i remembered that you have to enable http in xcode now because of the security has blocked a cleartext HTTP.

setting in your info.plist

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>example.com</key>
        <dict>
            <key>NSExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSIncludesSubdomains</key>
            <true/>
        </dict>
    </dict>
