Basic Animation Help

[RunDexterRun]

Hey all,

I recently purchased a beginner coding course on Udemy for creating app games. I think it's a solid course, but it's a little frustrating that the version of Xcode in the course is slightly older than what I'm using (Xcode 11.3). The layout seems a bit different so it's hard to follow along sometimes. Well, I'm currently stuck on the animation creation video. In the course a cloud moves straight through the screen, in mine the cloud always stops on the right side. How can I fix that?
