This application is an alert project. To alert user, there is a notification.
First of all, I have designed the application.
Then, in order to display alert notification to user I have created an alert by using UIAlertController. This alert is located in alert function for different cases.
Lastly, I have called the function for different cases when the user click "Sign up" button.
When the user wants to sign up, will see this screen below.
