nn-license

Binary license validator for nn-llm and nn-transcriber packages.

What is this?

This package ships a compiled xcframework (NNLicense.xcframework) that validates license keys at runtime. The source code is compiled to binary so it cannot be easily read or modified by end-users.

How it works

Other packages (nn-llm, nn-transcriber) depend on this pod and call:

import NNLicense

let valid = LicenseValidator.isValid("NK-xxxx...")

Building the xcframework

If you modify the source code in Sources/NNLicense/, rebuild the xcframework:

cd packages/nn-license
chmod +x build-xcframework.sh
./build-xcframework.sh

This compiles LicenseValidator.swift → ios/Frameworks/NNLicense.xcframework (binary only, no source).

Usage in other modules

1. Add dependency in podspec:

   s.dependency 'NNLicense'

2. Import and use:

   import NNLicense
   
   let isLicensed = LicenseValidator.isValid(key)
