Program/Source Code:

The source code to use enumeration constants using the switch statement is given below. The given program is compiled and executed successfully.

// Swift program to use enumeration constants using

import Swift

enum Colors:Int {
    case RED
    case GREEN
    case BLUE
    case WHITE
}

var FavColor = Colors.GREEN

switch FavColor {
    case .RED:
    print("Red")

    case .GREEN:
    print("Green")
    
    case .BLUE:
    print("Blue")
    
    case .WHITE:
    print("White")
}

Output:

Green

...Program finished with exit code 0
Press ENTER to exit console.
