Learn Swift: Functions

Continue your Swift journey by learning functions — reusable and callable code blocks!
Continue your Swift learning journey! Learn how to create reusable blocks of code using functions. These functions will allow your programs to become more flexible with the use of parameters and arguments. You'll also make use of functions' return values for storage or manipulation.



### Take-Away Skills
By the end of this course, you will be able to:
* Reuse blocks of code by defining and using functions.
* Incorporate parameters and arguments into your functions.
* Return values from a function and store them for later use.

We recommend that you complete [Learn Swift: Arrays, Sets, and Dictionaries](https://www.codecademy.com/learn/learn-swift-arrays-sets-and-dictionaries) before completing this course.
