Hi, thanks for spotting this. I will check it out and get back soon.

Hi, I have tested against iOS simulator for both 9.3+iPhone6 and 11.0+iPhone8, and none of them throw such errors.

By looking into your error stack trace above, have you ever run react-native link react-native-nfc-manager to link the native module? It looks like that you're missing native module^^

[milon87]

yes, I have linked. in android, it works perfectly. Ok, I will test again

Can you check if the ios project is properly linked?

1. the library project has been added into your Libraries group
2. the static lib libNfcManager.a should show in the Build Phases -> Link Binary With Libraries section.

If they are not appeared, you can manually link this library for now by following this instruction: https://facebook.github.io/react-native/docs/linking-libraries-ios.html

Hi, I still cannot reproduce this error. Can you check which XCode version you currently use? NFC related functionality only available for XCode 9.

[milon87]

OS: Sierra 10.12.6
XCode Version: 8.3.1 (8E1000a)
ok in that case I will update to 9 and i will let you know

Hi @milon87 any update for this one? I think the XCode 9 is definitely required for NFC development. Hope your upgrading process goes smoothly~

This happens because of Xcode version.
required version 9
