Xcode 8.3 warning

[Huang-Libo]

warning info:
Assigning to 'id<CALayerDelegate> _Nullable' from incompatible type 'FBShimmeringLayer *const __strong'

- (void)_createMaskIfNeeded
{
  if (_shimmering && !_maskLayer) {
    _maskLayer = [FBShimmeringMaskLayer layer];
    _maskLayer.delegate = self;     // -> warning here ...
    _contentLayer.mask = _maskLayer;
    [self _updateMaskColors];
    [self _updateMaskLayout];
  }
}

This can be fixed easily by making the change on line 136 of FBShimmeringLayer.m:

@interface FBShimmeringLayer ()
<CALayerDelegate> // <= right here
@property (strong, nonatomic) FBShimmeringMaskLayer *maskLayer;
@end

There's another error in the FBShimmering protocol lines 39-40. Anyone know how to resolve it?

Update: I just commented it out ¯_(ツ)_/¯
