What is TAPI?

TAPI is a Text-based Application Programming Interface. It replaces the Mach-O Dynamic Library Stub files in Apple's SDKs to reduce the SDK size even further.

The text-based dynamic library stub file format (.tbd) is a human readable and editable YAML text file. The TAPI projects uses the LLVM YAML parser to read those files and provides this functionality to the linker as a dynamic library.
