weak reference error in xcode 8.3.2

Hi,

Bolts-ObjC-master/Bolts/iOS/BFAppLinkReturnToRefererView.m:33:1: error: cannot synthesize weak property in file using manual reference counting @implementation BFAppLinkReturnToRefererView { ^ In file included from Bolts-ObjC-master/Bolts/iOS/BFAppLinkReturnToRefererView.m:11: Bolts-ObjC-master/Bolts/iOS/BFAppLinkReturnToRefererView.h:57:70: note: property declared here @property (nonatomic, weak) id delegate;

For at least xcode 8.3.2. MacOS, and iOS targets.
