Corrupted Project

So I was trying to save an image in core data and created an NSManagedObject Subclass. After doing so I decided I didn't like it so I deleted the files, but now every time I run the project it creates a properties file with an error saying it can't find a UIImage in scope and the file isn't editable so I can't import UIKit. I've tried deleting the file in finder, deleting the whole project and then redownloading it from GitHub, but to no avail. Basically I want it to stop making the subclass every time I run the project.

Please help. Thanks!
