In this article you will learn |Typealias| 🚀
Introduction
Swift Typealias is used to provide a new name for an existing data type in the program. Once you create a typealias, you can use the aliased name instead of the exsisting name throughout the program.
Typealias doesn’t create a new data type, it simply provides a new name to the existing data type. It does not make any effect to your code , its just make your code more readable and easy .
Why we use it ?
The reason is why we use in a line is to just make your code clear and readable . By using them in a smart way they can be really useful in your codebase.

You can use swift typealias with most of the types :
- Built-in types

typealias MyEmployees = [Employee]
func listEmployees(enterEmployees: MyEmployees) {}MY LINKEDIN : linkedin.com/in/my-pro-file
