How to merge multiple CAShapeLayers into one in swift

Question

I've got multiple bezier paths which are incorporated into CAShapeLayers for animation purposes. I need to know if it is possible to merge all of the layers into one collection object so that I can scale it in the following way:

shapes.transform = CATransform3DMakeScale(2, 2, 1)

Does anybody know how to do this?

If you apply the transform to the layers' super layer, does it apply the transfer to them all? – Cariecaries

I don't know, I'll have a try – Forcefeed

If the shapes have the same properties (stroke width, fill color, line caps etc.) you can construct a single path. Another solution is applying the transform to each layer. – Graveyard
