Swift: Switch Statement Compound Cases

Switch Statement Compound Cases in Swift:

The switch statement’s ability to use multiple values in a single case is also noteworthy. They’re called switch statement compound cases in Swift. Each value within a compound case will be matched to the given expression using the switch statement.

Using a switch statement, the following code checks the value of nation and determines the continent on which it is located. Compound cases are useful because a continent may contain multiple nations:

let nation = "Pakistan";
 
switch nation {
  case "Brazil", "Argentina", "Peru":
    print("\(nation) is in South America.");
  case "Nigeria", "Ethiopia", "Egypt":
    print("\(nation) is in Africa.");
  case "Nepal", "Maldives", "Pakistan":
    print("\(nation) is in South Asia.");
  default: 
    print("This nation is located somewhere on the world!");
}
// Prints: Pakistan is in South Asia.

Take notice of how:

• A comma separates the multiple values or items in a compound case.
• We used string interpolation to output the value of nation within the String of the print() statement.
