pass delegate from one VC to another withOut using prepareForSegue
<p>So i know how to make delegates and pass them using prepare for segue; however, I have a 3 Views (lets Call them A, B &amp; C). View A connect to view B. View B has a button that leads to view C. In View C, there is a switch that toggles...</p>

<p>view connection: A->B->C</p>

<p>I want to make it so when the switch is toggled in View C, View A knows about it. without using KVO since the relationship is still 1-to-1</p>
