[IbrahimCanKALYA]

Hi @cjam react-native-events has dependency events : v1

events current version is 3.0.0 this dependency different cause build problems with other libraries.
if react-native-events upgraded 1.0.20 the problem will fixed.

I tried to upgrade & create PR but example app only work on iphone emulator, on iphone device debug run it throws error named Spotify.h not found

Anyway i upgraded the version of react-native-events & i tried on iphone emulator it seem fine, if u have time to look on this , i'll appreciate.

Thanks in advance
