iOS mDocs Holder SDK

The iOS mDoc Holder SDK is based on the ISO/IEC 18013-5 standard which establishes an interoperable digital representation of mobile-based credentials such as mobile drivers licenses (mDL). However, this SDK can extend the same technology and architecture to more then just mDLs, but rather any conforming mobile document (mDoc) - a term defined in ISO/IEC 18013-5.
