Swift: Iterating Through a Set

Iterating Through a Set in Swift:

A forin loop can be used to iterate through each value in a set in Swift.

We can use the following syntax to iterate over every item in a set:

for Value in setName {
  // Body of loop
}

Assume we’re baking a cake. Let’s make a set that contains all of the ingredients for baking a cake:

var cake: Set = [" Butter", "Eggs", "Vanilla Extract","Baking Powder", "Milk", "Sugar"];

We can use a forin loop to print() all of the necessary ingredients:

for Allingredient in cake {
  print(Allingredient);
}

The value of the current iteration is stored in our placeholder, Allingredient. When we run this code, we should get something like the following output:

Milk
Butter
Baking Powder
Sugar
Eggs
Vanilla Extract

Because sets are unordered, the output may differ each time we run our code.
