Biometrics not working on iOS 18

[radekzz]

Hi guys, library works fine on Android and iOS 17, but not on iOS 18.

 rnBiometrics.biometricKeysExist().then((resultObject) => {
    const { keysExist } = resultObject;

    if (keysExist) {
      console.log('Keys exist');
    } else {
      console.log('Keys do not exist or were deleted');
    }
  });

Always result in keysExist = false

const { success, error } = await rnBiometrics.simplePrompt({
      promptMessage: 'Confirm fingerprint',
      cancelButtonText: intl.formatMessage({ id: 'common.cancel' }),
    });

    if (success) {
      Logger.log('🎟', 'Successful biometrics provided');
    }
    if (error) {
      Logger.log('🎟', `Biometrics prompt error: ${error}`);
    }

Always result in Biometrics prompt failed with exception: Error Domain=com.apple.LocalAuthentication Code=-1000 "UI service connection invalidated." UserInfo={NSDebugDescription=UI service connection invalidated., NSLocalizedDescription=Authentication failed.} but i think this is only iOS 18 simulator bug. However on real device prompt always return false.

Do you have any idea? As i see library is not maintained anymore so i hope someone faced this problem and can give me some advice.

Facing the same issue, have you been able to fix this?

Unfortunately not. However it seems not all real devices are facing this issue. I also tried other libraries with same result.

If you are using react-native-permission lib then used this version "react-native-permissions": "^3.8.4",

@amitmehtacode Are you saying asking Face ID request permission before with "react-native-permissions" fix this issue?

I did some research and it seems to be a bug only in the simulator on IOS 18 and not in the lib, it seems to work on real devices.
