Building NFC extension for iOS

[trevix]

I am building a LCB extension that should enable LC standalone to read text from NFC tags.
I am doing this using Claude Code (couldn't do without...) and direct CoreNFC system framework binding.

Apple Developer setup should be correct: Bundle ID, provisioning profile, and entitlements properly configured
Everything seems to work, compile, install, init, but return false on nfcIsAvailable().
The custom plist, loaded in the copy pane, is fine but Claude (ha!) thinks that:

LiveCode's standalone builder is NOT extracting and applying these entitlements to the final app binary

Any info you can share on this?
I have been running circles for a while now. The last thing suggested by Claude is to manually inject the entitlements after the build.
Beside how annoying this is, having to create a standalone and side load it to my iPhone 8 instead of yusing "Test", is this a correct approach?

Thanks for any help.
PS: since LC does not update LCB, it would be nice at least to have a list of things that they know don't work with it. It would be helpful.

Forgot the lcb code:
