Have you tried making it non-private? Also, I’m seeing that classes extending Obj-C classes need to be

final

. https://kotlinlang.org/docs/native-objc-interop.html#subclassing-swift-objective-c-classes-and-protocols-from-kotlin

I also have the same error as Carlo, although the func tagReaderSessionDidBecomeActive is called correctly, however the func tagReaderSession(session: NFCTagReaderSession, didDetectTags: List<*>) gives the error “Delegate does not implement -tagReaderSessiondidDetectTags method” . Could this be a recognized bug? I read that with swift the delegate implementation code is this “tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) ” but in kotlin it is different “tagReaderSession(session: NFCTagReaderSession, didDetectTags: List<*>)”

Ah yeah you might have to change the ObjC name with an annotation. The compiler might be mangling that.

Hi, thanks for your time, but: @ObjCName is not applicable on overrides

Shoot. Sorry!

any help is appreciated

thanks for the help, any suggestion is welcome, also because I haven’t found any example of using nfc for ios with kotlin multiplatform
