Usage

Configuration of custom flow layouts is pretty easy:

var contentFlowLayout: ContentDynamicLayout = TagsStyleFlowLayout()

contentFlowLayout?.delegate = self
contentFlowLayout?.contentPadding = ItemsPadding(horizontal: 10, vertical: 10)
contentFlowLayout?.cellsPadding = ItemsPadding(horizontal: 8, vertical: 8)
contentFlowLayout?.contentAlign = .left

collectionView.collectionViewLayout = contentFlowLayout!
collectionView.reloadData()

Also, you have to implement ContentDynamicLayoutDelegate protocol:

public protocol ContentDynamicLayoutDelegate: class {
    func cellSize(indexPath: IndexPath) -> CGSize
}

func cellSize(indexPath: IndexPath) -> CGSize {
    return cellsSizes[indexPath.row]
}
