title: Adding element to an array while iterating over it
body: <p>I have a for loop that loops over each element in an array. Under a certain condition, I add another element to that array inside the loop. However, the loop doesn't take that new element into account. If there are 6 items originally in the array and while looping through, I add 2 more, it still only loops 6 times. How can I fix this?</p>
  
  <pre><code>for ingredient in ingredientList {
      if ingredient.name == "banana" {
          var orange = Ingredient(name: "orange")
          ingredientList.append(orange)
      }
      if ingredient.name == "orange" {
          // this never executes
      }
  }
  </code></pre>
  
  <p>If one of my ingredients is a banana, add an orange to the list. However, the loop never even considers the newly added element. How can I accomplish something like this and why doesn't it work?</p>
