For version 0.6.1 with Swift 3.0

1.Added @objc before public protocol RAReorderableLayoutDelegate: UICollectionViewDelegateFlowLayout and public protocol RAReorderableLayoutDataSource: UICollectionViewDataSource

the code will be:

@objc public protocol RAReorderableLayoutDelegate: UICollectionViewDelegateFlowLayout
@objc public protocol RAReorderableLayoutDataSource: UICollectionViewDataSource

2.setup your collection view delegate and datasource(Use RAReorderableLayout as its layout)

collectionView.delegate = self;
collectionVeiw.datasource = self;

You don't need to do something like layout.delegate = self at this version

3.Put all the delegate & datasource method into your view controller

Datasource:

- (NSInteger)numberOfSectionsInCollectionView:(UICollectionView *)collectionView;
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section;
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAt:(NSIndexPath *)indexPath;
- (CGFloat)collectionView:(UICollectionView *)collectionView reorderingItemAlphaInSection:(NSInteger)section;
- (UIEdgeInsets)scrollTrigerPaddingInCollectionView:(UICollectionView *)collectionView;
- (UIEdgeInsets)scrollTrigerEdgeInsetsInCollectionView:(UICollectionView *)collectionView;
- (CGFloat)scrollSpeedValueInCollectionView:(UICollectionView *)collectionView;

Delegate:

- (BOOL)collectionView:(UICollectionView *)collectionView allowMoveAt:(NSIndexPath *)indexPath;
- (BOOL)collectionView:(UICollectionView *)collectionView at:(NSIndexPath * _Nonnull)at canMoveTo:(NSIndexPath * _Nonnull)canMoveTo;
- (void)collectionView:(UICollectionView *)collectionView at:(NSIndexPath *)at didMoveTo:(NSIndexPath *)toIndexPath;
- (void)collectionView:(UICollectionView *)collectionView collectionView:(RAReorderableLayout *)layout willEndDraggingItemTo:(NSIndexPath * _Nonnull)indexPath;
- (void)collectionView:(UICollectionView *)collectionView collectionView:(RAReorderableLayout *)layout didEndDraggingItemTo:(NSIndexPath *)indexPath;
- (void)collectionView:(UICollectionView *)collectionView collectionView:(RAReorderableLayout *)layout willBeginDraggingItemAt:(NSIndexPath *)indexPath;
- (void)collectionView:(UICollectionView *)collectionView collectionView:(RAReorderableLayout *)layout didBeginDraggingItemAt:(NSIndexPath * _Nonnull)indexPath;
- (void)collectionView:(UICollectionView *)collectionView at:(NSIndexPath * _Nonnull)at willMoveTo:(NSIndexPath * _Nonnull)toIndexPath;

Then do what you need in all these methods. P.S. some method you don't need could be just empty
