Summary: Changelog: [iOS] [Changed] - New internal image attribution support, but files importing RCTImageLoader.h must be converted to ObjC++ This new interface is the same as RCTImageURLLoader, but with additional support to pass in optional attribution information. The attribution info is not strictly defined (we may do so in the future though), and it's up to the hosting application and RCTImageURLLoader classes to handle it.
