Swift - Associated value or extension for an Enum

Question

General question regarding swift enum.

I want to create an enum of \"icon\" and \"associate\" a value to the enum case

enum Icon {
  case plane
  case ar         


        

Answer 1

Shorter and safer code:

import UIKit

enum Icon: String {

    case plane, arrow, logo, flag

    var image: UIImage {

        // If the image is not available, provide a default value so we dont force optional unwrapping
        return UIImage(named: "\(self.rawValue).png") ?? UIImage()
    }

    var color: UIColor {
        switch self {
        case .plane: return UIColor.green
        case .arrow: return UIColor.green
        case .logo: return UIColor.green
        case .flag: return UIColor.green
        }
    }
}

// Usage
Icon.plane.color
Icon.arrow.image
