Tested environment (Emulator? Real Device?)

Both Emulator and Real Device

Steps to reproduce the behavior

[gurol]

I have fixed the error by making the following change in node_modules/react-native-iap/ios/RNIapIos.m file:

#import <IAPPromotionObserver.h>
to
#import "IAPPromotionObserver.h"

Fixed in 4.4.8. However, I'm not quite sure why this wasn't a problem in my env.
