Storing some asset information

Before we start with the scenes, we must create a class that will store some information about the files that are being used for our media edition. Add a new Swift file to our project and call it AssetInfo.swift. Start importing UIKit, as it is shown in the next line, because we are going to use the UIImage class:

class AssetInfo {

Now, we can start with the first attribute, that is the video thumbnail image. Add the following attribute to your class:
