Core Animation is an extraordinary toolkit, and UIKit wraps it in a simple and flexible set of methods. And because it's so simple to use, you really have no excuse for not using it.
In this project you learned about the
animate(withDuration:) method of
UIView, spring animations, as well as alpha values and
Remember, animation isn’t just there to make our apps look pretty – it also helps guide the users eyes.

Your users will thank you for it!
Anyone can sit through a tutorial, but it takes actual work to remember what was taught. It’s my job to make sure you take as much from these tutorials as possible, so I’ve prepared a short review to help you check your learning.
One of the best ways to learn is to write your own code as often as possible, so here are three ways you should try your new knowledge to make sure you fully understand what’s going on:
isHiddenproperty, but you'll need to switch to
isHiddenis either true or false, it has no animatable values between.

SPONSORED Catch bugs as soon as they happen and know exactly why a crash occurred by integrating Instabug's SDK in one minute. You will automatically receive device data, network logs, and reproduction steps with every bug and crash report.
One of the most effective motivators of success is sharing your progress with other people – when you tell folks what you're doing and what you've learned, it encourages you to come back for more, which in turn will help you reach your app development goals faster.
So, now that you've done all the hard work it's time to share your success: tell folks that you've completed this project, either by clicking the button below to start composing a tweet, or by writing your own message from scratch. This will definitely encourage you to keep learning, but it will also help other folks discover my work – thank you!
