Answer by ibash for Analysing Assets.car file in iOS

All the prior mentioned tools do not extract PDFs correctly. Within the QLCARFiles project there's a utility called carDump that does extract files correctly.

In short:

1. Clone the project from https://github.com/Timac/QLCARFiles
2. Open in xcode
3. Select the carDump scheme and build
4. Use the cli:

mkdir outputcarDump Assets.car output
