It’s not unusual to have some unused images when compiling a project, and if you’ve got a large number of unused images tracking each down can be a difficult task, and greatly increase the size of your app’s bundle.
Here’s an open source tool by Jeff Hodnett for finding unused images called Unused. Unused displays a list of any unused image files and their location for a specific Xcode project. You can also export the results to a text file.
Here’s an image from the Unused homepage demonstrating the tool in action:
You can find Unused on its homepage here.
On the homepage you’ll find links to directly download the source, and to the Github page. Note that on the Github page it mentions a Mac app store link to download Unused that appears to no longer be relevant.
