HEllo everyone =)

1) I added the flags to project, I used hasSuffix("png") method to extract, but when I display it in table view they appear the way they are, estonia2x@ 3X@ etc. Then I added them into Assets.xcassetes. I dont know how to call them. should I call them one by one or is there a easier way because previous method is not working here .

2) I managed to add individual flag, I added label for country name it displays as estonia@2x etc. How can I solve this?

3) for explanation of individual country. i am have no idea how to start. should I create a new swift file, where should I write the information and how can I call them .

import UIKit

class TableTableViewController: UITableViewController {

    var flagNames = [String]()
    //var flagImage = [UIImage]()

    override func viewDidLoad() {
        super.viewDidLoad()
        title = "Fun with Flags"
        navigationController?.navigationBar.prefersLargeTitles = true

        let fm = FileManager.default
        let path = Bundle.main.resourcePath!
        let items = try! fm.contentsOfDirectory(atPath: path)

        for item in items {
            if item.hasSuffix(".png") {
                flagNames.append(item)
            }
        }
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return flagNames.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
        cell.textLabel?.text = flagNames[indexPath.row]
        cell.imageView?.image = UIImage(named: flagNames[indexPath.row])
        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        if let vc = storyboard?.instantiateViewController(withIdentifier: "Detail") as? DetailViewController {
            vc.selectedCountry = flagNames[indexPath.row]
            navigationController?.pushViewController(vc, animated: true)
        }
    }
}

import UIKit

class DetailViewController: UIViewController {

    @IBOutlet var imageView: UIImageView!
    @IBOutlet var countryNameLabel: UILabel!
    @IBOutlet var countryExplanation: UILabel!

    var selectedCountry: String?

    override func viewDidLoad() {
        super.viewDidLoad()

        title = selectedCountry
        navigationItem.largeTitleDisplayMode = .never
        navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .action, target: self, action: #selector(shareTapped))

        if let imageToLoad = selectedCountry {
            imageView.image  = UIImage(named: imageToLoad)
            countryNameLabel.text = selectedCountry
            countryExplanation.text = selectedCountry
        }
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        navigationController?.hidesBarsOnTap = true
    }

    override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        navigationController?.hidesBarsOnTap = false
    }
    @objc func shareTapped() {
        let vc = UIActivityViewController(activityItems: [imageView.image!], applicationActivities: [])
        vc.popoverPresentationController?.barButtonItem = navigationItem.rightBarButtonItem
        present(vc, animated: true)
    }
}

Okay I solved most of it, but I am still stucked at the main screen. Xcode includes all the versions of the flags. 2x,3x. I believe something wrong with my suffix method.
