If we want to go through every individual value contained in a set, we can use a for-in loop!

To iterate over every item of a set, we can use this syntax:

for Value in setName {
  // Body of loop
}

Imagine we are making cookies. Let’s create a set that stores the necessary ingredients for baking chocolate chip cookies:

var chocoChipCookies: Set = ["Flour", "Chocolate Chips", "Butter", "Eggs", "Sugar", "Baking Powder"]

We can use a for-in loop that will print() all the ingredients we need:

for ingredient in chocoChipCookies {
  print(ingredient)
}

Our placeholder, ingredient, stores the value of the current iteration. When we run this code, we will receive something similar to the following output:

Flour
Chocolate Chips
Eggs
Baking Powder
Butter
Sugar

Sets are unordered, so this output could look different every time we run our code.
