Good Evening Community, I am a beginner in coding and I am using swift. I got started out with a video from a friend on treehouse about learning to create a simple swift app. However, during the coding challenge area i got very confused because I have no idea what a class, inheritance or a struct is. Does anyone have a recommendation about where to start to get familiar with these coding languages and what they exactly mean? Thank you in Advance.

If you already do know Swift basics and it's specifically classes, objects, and the like that you are unfamiliar with then you can skip some of the early courses and jump right into the Object-Oriented Swift 3 course. Which is where those topics are introduced.
I would mostly recommend you start at the first course though. As the subsequent courses assume you have completed them, and you might learn something else new that you have not learned before.

2,489 PointsHi Charles, I'm a beginner as well and all I can say is what helps me is also doing some research through youtube as well as taking this course here on treehouse has helped me. A class is a blueprint where you can include variables and a function within it. Once you create that class you can call that class back with just the name you called it. So for instance if you wrote class fastCar { } so anything you write within the curly braces becomes the blueprint for that class. So then later in your script you can call the class again fastCar that will have everything you already need within it. The class itself will perform whatever you want it to do which is an instance. These instances are called objects that you created within the class. In a nutshell its just shorthand writing so you don't have to keep on writing the same thing over and over again which is what makes classes so attractive.
