I had an old app icon in xcode that I had just attached to the program to see how it looked in the simulator. I made changes, deleted the images, and replaced them in Xcode. However, they are still the old ones in the simulator. I tried resetting it and everything. Does it keep a cache somewhere?
EDIT: Solved by cleaning project.
Have you tried cleaning?
From the Xcode “Product” menu, choose “Clean” or “Clean Build Folder” if you hold alt/option.
