Example of using continue in a loop

ContinueExample.swift

import UIKit

let puzzleInput = "great minds think alike"
var puzzleOutput = ""
let charactersToRemove: [Character] = ["a", "e", "i", "o", "u", " "]


/// When using `continue` in an `if` statement (or switch) of a loop, the
/// loop immediately goes to the next iteration of the loop with completing
/// the rest of the current loop iteration.
/// This is different from a `break` that would simply end the loop.

/// If you run this example (adapted from The Swift Programming Language),
/// you'll see that when `continue` is hit, "contains vowels" is skipped.
for character in puzzleInput {
  if charactersToRemove.contains(character) {
    print("continue")
    continue
  } else {
    puzzleOutput.append(character)
    print("appended")
  }
  print("contains vowels")
}
print(puzzleOutput)
