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
