Unwind Segue Hairpinning

Hi all,

Picture a simple story board with three view controllers in a “V” shape where View controller A has a segue to B and a segue to C.

We want be able to unwind from view controller B into view controller C.

This is proving to be far more difficult that we had expected to be and even after watching a number videos and working through a few tutorials we are still stumped.

Could someone possibly help point us in the right direction?

Many thanks,
