Learn how to use for-in loops for Swift, including examples using arrays, range operators, dictionaries, and enums.

In layman’s terms, when something runs in a loop, it repeats the same things again and again. For example, a loop would be iterating through the number of blog posts and displaying them on the main page.

There are different types of loops for control flow in Swift. These are for-in, forEach, while, and repeat-while loops. In this article, we’ll go through a basic overview of for-in loops in Swift. Then, we’ll demonstrate how to work with them using examples and use cases with different data types.

We’ll focus on the following:

• The syntax of for-in loops
• Arrays
• Range and stride
• Dictionaries
• Enums

To follow along, you should have basic knowledge of the Swift language.
