[iOS] (TouchID) Dialog sometimes not showing on iOS 13

[LasseSLambertsen]

Hi, I've just implemented this library, but experiencing some problems on iOS 13.

The TouchID dialog, doesn't always show, but when touching the fingerprint scanner, it quickly shows and authenticates.

I'm running newest RN 0.61.1 and react-native-fingerprint-scanner 3.0.0

Thanks for opening an issue. Is this happening on a real device or the simulator? What model is it?

Happening on a real iPhone 8

Also running into this: I assume it's to do with some new iOS 13 change.

It looks like this is due to an upstream bug in iOS 13 (so not something this library can address). Sources:

There are some reports that iOS 13.1.3 fixes this: https://github.com/EddyVerbruggen/cordova-plugin-touch-id/issues/84#issuecomment-544321805

Yes, I am also seeing this being fixed with iOS 13.1.3

Going to close, thanks all!
