I have successfully parsed and decoded the JSON data and it displays in the console. I don't know how I would set up pagination with the api and display all of the data when I scroll down on the tableView. The API I'm using is https://rickandmortyapi.com/api/character/. Thank you for all your help in advance!

This is the code in my main ViewController

import UIKit



struct PagedCharacters: Codable {

    struct Info: Codable {

        let count: Int

        let pages: Int

        let next: String

        let prev: String

    }



    struct Results: Codable {

        let name: String

        let status: String

        let species: String

    }



    let info: Info

    let results: [Results]



}





class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {



    @IBOutlet var uiTableView: UITableView!



    override func viewDidLoad() {

        super.viewDidLoad()

        getRickAndMortyData()





        self.uiTableView.dataSource = self

        self.uiTableView.delegate = self



        // Do any additional setup after loading the view.

    }



    func getRickAndMortyData() {



        //create instance of the url

        let url = "https://rickandmortyapi.com/api/character/"



        //construct the url, use guard to avoid nonoptional

        guard let urlObj = URL(string: url) else

        { return }



        //fetch data

        URLSession.shared.dataTask(with: urlObj) {(data, response, error) in



            //to avoid non optional in JSONDecoder

            guard let data = data else { return }



            do {

                //decode object

                let downloadedRickAndMorty = try JSONDecoder().decode(PagedCharacters.self, from: data)

             DispatchQueue.main.async {

                    self.uiTableView.reloadData()

                }

               print(downloadedRickAndMorty)



            } catch {

                print(error)



            }



            }.resume()



    }





    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        // #warning Incomplete implementation, return the number of rows

        return 0

    }



    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

        guard let cell = tableView.dequeueReusableCell(withIdentifier: "rickandmortyCell") as? CharacterTableViewCell else { return UITableViewCell() }



        cell.nameLabel.text = "Name: " + PagedCharacters.Results[indexPath.row].name



        return cell

    }





}

This is my tableviewcell class

import UIKit



class CharacterTableViewCell: UITableViewCell {



    @IBOutlet weak var nameLabel: UILabel!





    override func awakeFromNib() {

        super.awakeFromNib()

        // Initialization code

    }



    override func setSelected(_ selected: Bool, animated: Bool) {

        super.setSelected(selected, animated: animated)



        // Configure the view for the selected state

    }



}

This is the data I'm getting in my console when the parsed data is printed. I'm still not getting all the data from the different pages.

PagedCharacters(info: API_Practice.PagedCharacters.Info(count: 493,
pages: 25, next: "https://rickandmortyapi.com/api/character/?page=2",
prev: ""), results: [API_Practice.PagedCharacters.Results(name: "Rick
Sanchez", status: "Alive", species: "Human"),
API_Practice.PagedCharacters.Results(name: "Morty Smith", status:
"Alive", species: "Human"), API_Practice.PagedCharacters.Results(name:
"Summer Smith", status: "Alive", species: "Human"),
API_Practice.PagedCharacters.Results(name: "Beth Smith", status:
"Alive", species: "Human"), API_Practice.PagedCharacters.Results(name:

API_Practice.PagedCharacters.Results(name: "Alexander", status:

"Alien Googah", status: "unknown", species: "Alien"),
API_Practice.PagedCharacters.Results(name: "Alien Morty", status:
"unknown", species: "Alien"),
API_Practice.PagedCharacters.Results(name: "Alien Rick", status:
"unknown", species: "Alien"),
API_Practice.PagedCharacters.Results(name: "Amish Cyborg", status:
"Dead", species: "Alien"), API_Practice.PagedCharacters.Results(name:
"Annie", status: "Alive", species: "Human"),
API_Practice.PagedCharacters.Results(name: "Antenna Morty", status:
"Alive", species: "Human"), API_Practice.PagedCharacters.Results(name:
"Antenna Rick", status: "unknown", species: "Human"),
API_Practice.PagedCharacters.Results(name: "Ants in my Eyes Johnson",
status: "unknown", species: "Human")])

If you need anything else please let me know. Thank you!

There were many flaws in your logic, so I have rewritten it with minimal changes. Now it will serve your purpose.

import UIKit

struct PagedCharacters: Codable {

    let info: Info

    let results: [Results]



}

struct Info: Codable {

    let count: Int

    let pages: Int

    let next: String

    let prev: String

}



struct Results: Codable {

    let name: String

    let status: String

    let species: String

}

And here is the code for view controller class:

class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {



    @IBOutlet var uiTableView: UITableView!

    var aryDownloadedData:[Results]?

    var nextPageUrl:String!



    override func viewDidLoad() {

        super.viewDidLoad()

        getIntitalRickAndMortyData()





        self.uiTableView.dataSource = self

        self.uiTableView.delegate = self



        // Do any additional setup after loading the view.

    }

    func getIntitalRickAndMortyData(){

        aryDownloadedData = 

        //here first page is next page

        nextPageUrl = "https://rickandmortyapi.com/api/character/"

        getRickAndMortyData()

    }



    func getRickAndMortyData() {



        //construct the url, use guard to avoid nonoptional

        guard let urlObj = URL(string: nextPageUrl) else

        { return }



        //fetch data

        URLSession.shared.dataTask(with: urlObj) {[weak self](data, response, error) in



            //to avoid non optional in JSONDecoder

            guard let data = data else { return }



            do {

                //decode object

                let downloadedRickAndMorty = try JSONDecoder().decode(PagedCharacters.self, from: data)

                self?.aryDownloadedData?.append(contentsOf: downloadedRickAndMorty.results)

                self?.nextPageUrl = downloadedRickAndMorty.info.next



                DispatchQueue.main.async {

                    self?.uiTableView.reloadData()

                }

                print(self?.aryDownloadedData as Any)



            } catch {

                print(error)



            }



            }.resume()



    }





    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

        return self.aryDownloadedData?.count ?? 0

    }



    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {



        if let count = aryDownloadedData?.count, count>1{

            let lastElement = count - 1

            if indexPath.row == lastElement {

                //call get api for next page

                getRickAndMortyData()

            }

        }



        guard let cell = tableView.dequeueReusableCell(withIdentifier: "rickandmortyCell") as? CharacterTableViewCell else { return UITableViewCell() }



        cell.nameLabel.text = "Name: " + (self.aryDownloadedData?[indexPath.row].name ?? "default")



        return cell

    }
