SwiftODB2 help?

Hey I need some help getting my OBD2 app to work. I'm using GitHub - kkonteh97/SwiftOBD2: The versatile OBD2 toolkit for Swift developers. Diagnose, explore, and build custom vehicle apps with ease. Includes an emulator for streamlined prototyping. to manage the data and to just display the error codes and live metrics but every time I run it I get some sort of error, most recently "Failed to create Frame for raw data:". Could someone help me out?
