Next level Coding is pretty simple to use, and a great way to learn swift, a programming language of the many that are out there. When you open the app, there will be three tabs. It will bring you to the first one, and it will say "Download Xcode", and it will give you a wall of text. This is information on how to download Xcode, the software you use to program swift. When you finish, click next, and it will give you information on how to get around the Xcode app. After you read the next wall of text, and the image, click next again, and so on. Eventually, there will be no image, a paragraph, and it will tell you to move to the next tab. You do the same thing for the next tab, but there will be a lot more times hitting next. After you do that, it will instruct you to go to the next tab. This tab is used to put your skills to the test. Enter the answer to the first question. Remember, you have to type it exactly how it is. Read the question carefully. No extra spaces, caps, or anything. When you have typed the answer, click done. It will say if you were right or wrong. It will move to the next question. After 8 questions, it will give you your score, and an option to reset the quiz. Good luck!
