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

Here's an example code snippet that you can use to create a tableview displaying the flags of countries in eu using Swift:

main.swift
// Define the data source
let countries = ["Austria", "Belgium", "Bulgaria", "Croatia", "Cyprus", "Czech Republic", "Denmark", "Estonia", "Finland", "France", "Germany", "Greece", "Hungary", "Ireland", "Italy", "Latvia", "Lithuania", "Luxembourg", "Malta", "Netherlands", "Poland", "Portugal", "Romania", "Slovakia", "Slovenia", "Spain", "Sweden"]

// Define the view controller that conforms to the UITableViewDataSource protocol
class FlagTableViewController: UITableViewController {
    
    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return countries.count
    }
    
    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "flagCell", for: indexPath)
        
        // Set the cell text to the country name
        cell.textLabel?.text = countries[indexPath.row]
        
        // Set the cell image to the flag image
        let flagImage = FlagImage.getFlagImage(for: countries[indexPath.row])
        cell.imageView?.image = flagImage
        
        return cell
    }
}

// Create a helper class to return an UIImage object for a given country
class FlagImage {
    static func getFlagImage(for countryName: String) -> UIImage? {
        // Convert the country name to a 2-letter country code
        let countryCode = NSLocale.current.isoCode(for: countryName) ?? ""
        
        // Load the image asset based on the country code
        return UIImage(named: countryCode)
    }
}

In the code above, we define an array called countries that contains the names of the countries in the EU. We then define a FlagTableViewController class that conforms to the UITableViewDataSource protocol, which is responsible for providing the data to our tableview. In the tableView(_:numberOfRowsInSection:) method, we return the number of countries in our countries array. In the tableView(_:cellForRowAt:) method, we dequeue a reusable cell and set its text label to the name of the country. We then use a helper class called FlagImage to get the UIImage object of the flag image for the country, and set the cell's image to the flag image.

Note that we use a helper class called FlagImage to get the UIImage object for the flag image based on the ISO code of the country. You can either use image assets for each country flag or you can use libraries such as emoji-flag-swift to get an emoji flag based on the ISO code.
