Is the .app directory cleaned (all files removed) when a new version of an iOS app is distributed?
I have an app with some images in it. If I deploy a new version in the simulator and some images have been removed, they are still in the .app folder. The removed images are only deleted when I delete the app entirely from the simulator and re-deploy. This is not a problem in the simulator, however in the final product, this might cause a problem if I had to rename or remove some of the images.

My question is: Is it the case that files are only overwritten (the .app directory is not cleaned) when an app is downloaded from the app store?
