Looping with for loops

for loops allow you to execute code for each element in a collection or range. In this recipe, we will explore how to use for loops to perform actions on every element in a collection.

Getting ready

In this recipe, we won’t be using any components from the previous recipes, so you can create a new playground for this recipe.

How to do it...

Let’s create some collections and then use for loops to act on each element in the collection:

1. Create an array of elements so that we can do something with every item in the array:

   let ledZeppelin = ["Robert", "Jimmy", "John", "John Paul"]

2. Create a loop to go through our theBeatles array, and print each string element that the for loop provides:

   for musician in ledZeppelin {

          print(musician)

   }

3. Create a for loop that executes some code a set number of times, instead of looping through an array. We can do this...
