What is CoreExtendedNFC?

CoreExtendedNFC is a Swift package that layers high-level NFC protocol logic on top of Apple's CoreNFC, letting iOS apps identify, read, write, and dump memory from tags like Ultralight, NTAG, DESFire, FeliCa, ISO 15693, and even eMRTD passports. It solves CoreNFC's lack of unified abstractions for card families—handling everything from ATQA/SAK decoding to DESFire chaining, passport BAC authentication, and exports in hex, JSON, Flipper NFC, or Proxmark3 formats via async/await APIs. Add it easily through Swift Package Manager in Xcode, with zero runtime dependencies beyond CoreNFC.

Why is it gaining traction?

Unlike raw CoreNFC, which sticks to transport and basic NDEF, this github swift repo delivers ready-to-use operations like one-shot scans, full dumps, and crypto primitives (AES-CMAC, 3DES) without external libs—perfect for swift package dependencies and swift package index integration. Developers dig the mock transport for unit tests, passport reading with MRZ keys, and seamless swift package manager xcode workflows, plus an example app showcasing scanner, NDEF tools, and exports. At 67 stars, it's pulling in iOS NFC tinkerers tired of reinventing protocols.

Who should use this?

iOS devs building tag dumpers, security audit apps, or passport readers who need robust CoreNFC extensions without libnfc ports. Hardware hackers flashing Flipper/Proxmark3 dumps, or teams handling mixed tag fleets in inventory/asset trackers. Ideal for swift github app or swift github client projects requiring swift package traits like testability and async NFC flows.

Verdict

Grab it for iOS 15+ NFC prototypes—docs shine with quick starts and standards refs, 319 tests cover mocks well—but 1.0% credibility and low stars signal early maturity; test on real hardware before prod. Solid foundation for github swift foundation control in NFC-heavy apps.
