App crash on CameraRoll.saveToCameraRoll in iOS in react-native

Question

I am trying to save a screenshot to Camera Roll in my react-native app in iOS but as soon as the CameraRoll.saveToCameraRoll is called the app crashes. It was working till iOS 10 and react-native 0.47. And it is working perfectly fine in Android.

I already have the permissions required for iOS 10+ in Info.plist.

This is my code for saving the image to Camera Roll.

CameraRoll.saveToCameraRoll(mUri, 'photo')
.then(()=>console.log('saved to CameraRoll'))
.catch(()=>console.log('error in saving'))

Note that I am not getting any of the console logs of above two. It is a native crash and below is the crash thread.

I get same problem too. Fixed by adding NSPhotoLibraryAddUsageDescription("Privacy - Photo Library Additions Usage Description") in info.plist.

It's a new rule for iOS 11.
