create a tableview displaying the flags of countries in eu as emojis in swift

To create a tableview displaying the flags of countries in the European Union as emojis in Swift, we will use the following steps:

  1. Create an array of EU country codes.
  2. Create a UITableViewDataSource class for our tableview.
  3. Implement the numberOfRowsInSection method to return the number of countries in our array.
  4. Implement the cellForRowAtIndexPath method to display the emoji flag.
  5. Register the tableview cell class in our view controller.
  6. Set the view controller as the tableview's delegate and data source.

Here's the code:

main.swift
import UIKit

class ViewController: UIViewController {
    
    let euCountries = ["๐Ÿ‡ฆ๐Ÿ‡น", "๐Ÿ‡ง๐Ÿ‡ช", "๐Ÿ‡ง๐Ÿ‡ฌ", "๐Ÿ‡ญ๐Ÿ‡ท", "๐Ÿ‡จ๐Ÿ‡พ", "๐Ÿ‡จ๐Ÿ‡ฟ", "๐Ÿ‡ฉ๐Ÿ‡ฐ", "๐Ÿ‡ช๐Ÿ‡ช", "๐Ÿ‡ซ๐Ÿ‡ฎ", "๐Ÿ‡ซ๐Ÿ‡ท", "๐Ÿ‡ฉ๐Ÿ‡ช", "๐Ÿ‡ฌ๐Ÿ‡ท", "๐Ÿ‡ญ๐Ÿ‡บ", "๐Ÿ‡ฎ๐Ÿ‡ช", "๐Ÿ‡ฎ๐Ÿ‡น", "๐Ÿ‡ฑ๐Ÿ‡ป", "๐Ÿ‡ฑ๐Ÿ‡น", "๐Ÿ‡ฑ๐Ÿ‡บ", "๐Ÿ‡ฒ๐Ÿ‡น", "๐Ÿ‡ณ๐Ÿ‡ฑ", "๐Ÿ‡ต๐Ÿ‡ฑ", "๐Ÿ‡ต๐Ÿ‡น", "๐Ÿ‡ท๐Ÿ‡ด", "๐Ÿ‡ธ๐Ÿ‡ฐ", "๐Ÿ‡ธ๐Ÿ‡ฎ", "๐Ÿ‡ช๐Ÿ‡ธ", "๐Ÿ‡ธ๐Ÿ‡ช"]
    
    @IBOutlet weak var tableView: UITableView!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        // Register tableview cell class
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
        
        // Set tableview delegate and datasource
        tableView.delegate = self
        tableView.dataSource = self
    }

}

extension ViewController: UITableViewDelegate, UITableViewDataSource {
    
    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // Return the number of countries in our array
        return euCountries.count
    }
    
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
        
        // Display the emoji flag for the corresponding country
        cell.textLabel?.text = euCountries[indexPath.row]
        
        return cell
    }
    
}

In this implementation, we create an array euCountries that contains the emoji flags of each EU country. We then register the UITableViewCell class in our view controller and set the tableview's delegate and datasource to the view controller. In the numberOfRowsInSection method, we return the number of countries in our array, and in the cellForRowAtIndexPath method, we display the emoji flag for the corresponding country in the cell.
