FYI, the change from assign to weak caused a crash for me:
Fatal Exception: NSInternalInconsistencyException
An instance 0x1062ae600 of class UICollectionView was deallocated while key value observers were still registered with it. Current observation info: <NSKeyValueObservationInfo 0x17082c9a0> ( <NSKeyValueObservance 0x171243ea0: Observer: 0x105d80720, Key path: contentOffset, Options: <New: YES, Old: NO, Prior: NO> Context: 0x105d80720, Property: 0x174c42d30> )
It occurs on iOS 9 & 10 (not 11), when popping from one VC to another, both with a collection view with a pull to refresh.

revert back to unsafe_unretained (same as assign). this is because of kvo. ref: https://stackoverflow.com/questions/10793206/how-do-you-remove-kvo-from-a-weak-property posted by sam himself
lemme know if this works
