    Once created, you don't need to remove the .atlas folder, just modify its contents using Finder. Make sure the .atlas folder has a blue icon in Xcode (folder reference), not a yellow one (group). – CodeSmile Feb 21 '14 at 17:37

    What Ray says is right, but I too have had problems with texture atlasas, I now delete and re-add the atlas folder from within Xcode. Also doing a "Build Clean" and/or a simulator "Restart and Reset" can help clear out any old cached images that might be hanging around. – fuzzygoat Feb 22 '14 at 08:29

I don't know if this is the reason, but I realized XCode copy new image files in the bundle directory, but doesn't remove the old ones that you have removed in your project. I think XCode only overwrite files. I remove Derived Data from organizer to make sure XCode is not loading at runtime a not removed old one. Same thing in the simulator, XCode doesn't remove old image files, so I delete the app and run it again from XCode.
