Variables and Constants

Variables and Constants

Variables and Constants is a core part of Swift. In this case file you'll learn what it is, why it matters, and how to use it in real code.

Understanding variables and constants well means you can read other people's Swift code with confidence, and avoid the most common beginner mistakes in this area.

Key points:

• What variables and constants means in the context of Swift
• A minimal example you can run or read in the playground on the right
• A common mistake to avoid when working with variables and constants

Tip: Try changing a value in the code on the right and re-running it — small experiments are the fastest way to build real intuition for variables and constants.
