How to get ASCellNode location on ASCollectionNode

[abhigourking]

Need to find the X, Y position of ASCellNode on the ASCollectionNode.
cellnode.frame always returning 0 for X and Y position.

The frameInWindow property does but it is only for the debugging purpose and can not be accessible in code.
// This should only be called for debugging. It's not thread safe and it doesn't assert.
// NOTE: Returns CGRectNull if the node isn't in a hierarchy.
- (CGRect)_frameInWindow

collectionNode.convert(cellNode.bounds, from: cellNode) Crashing the app Could not find a common ancestor between node1: cellNode and node2: <ASCollectionNode

collectionNode.convert(cellNode.bounds, from: nil) Returning some negative value

Anybody please help me out to find a solution.
My requirement is to get the ASCellNode's Frame in respect to ASCellectionNode
ie The Y position of frame should increase or decrease while scrolling the colllection node in (vertical layout).
