Associated values in swift enumeration and how to use them
In this tutorial, we will learn what is associated values in swift and how to use them. To learn more about associated values, suppose we are writing an iOS application in swift that will greet the user differently for the first time use and second time use.For example,suppose user 'Albert' is using the app for the first time. It will show one message Hello Albert ! Welcome to our app.. Similarly, after 10 time when he will open,it will print Hey Albert ! Thank you for using our app for more than 10 times. Please give us a rating on Appstore.. How we are going to use it ? Yes,we have different ways to solve this problem but we will learn how to solve it using enum in swift :.
