@dnlowman Have you tried iOS13? did you have this issue?

[dnlowman]

We're running iOS13 in production and are not experiencing this, could you please provide a stack trace @EsraaMahmoudMohamed?

There is no stack trace showing with this line; the app crashes without any errors. if I change All by any another type it will work all of these lines worked with me

 await StarPRNT.portDiscovery('LAN');
 await StarPRNT.portDiscovery('USB');
 await StarPRNT.portDiscovery('Bluetooth');

As mentioned above this only happens with iOS 13.3

@dnlowman @infoxicator We traced back the issue to this line in RNStarPrnt.m: https://github.com/infoxicator/react-native-star-prnt/blob/d4f523b57efe3d340557b680cd3552528d75d7fb/ios/RNStarPrnt.m#L69

I tried catching the error here, however, it crashed with no stack trace. I checked the StarIO.m and it seems that the available arguments are: https://github.com/infoxicator/react-native-star-prnt/blob/d4f523b57efe3d340557b680cd3552528d75d7fb/ios/Frameworks/StarIO.framework/Headers/SMPort.h#L68

Not sure why crash with 13.3 specifically, any idea why?

As a quick fix, we are now discovering each type separately.

Nice find @EsraaMahmoudMohamed, I will try to re-produce what you have found and get back to you on this.
