When iterating through a sequence, we might not need to use every single value. In these cases, it’d be nice to just tell our loop to skip a value. That’s where continue comes in.

If we wanted to only print out all the characters except for vowels ("a", "e", "i", "o", "u") in a String:

let challenge = "bring it" for char in challenge { switch char { case "a", "e", "i", "o", "u": continue default: print(char) } }

In the example above, we have a switch statement which checks char and if it is any of the following characters: "a", "e", "i", "o", and "u". Inside our case statement, if the character matches, we skip over it with continue. If our character is not a vowel, then we print it out.

When we run our code, it prints out:

b r n g t

Currently, in our for-in loop we print out every single number in the range, 1...9. However, we don’t want to print out the odd numbers.

Inside the for-in loop, add the code needed to skip over the odd numbers by adding:

  • An if statement that checks if num is an odd number.
  • Inside the body of the if statement, the continue keyword.
