In a previous article, I reverse-engineered the .car file format used to store the compiled assets of an Asset Catalog. I also demonstrated how to create a tool to manually parse such files. While this tool can extract a lot of information, it is cumbersome to use if you want to quickly see all the assets contained in a car file.
An Asset Catalog is an important piece of any iOS, tvOS, watchOS and macOS application. It lets you organize and manage the different assets used by an app, such as images, sprites, textures, ARKit resources, colors and data.
