Sorry guys Accidently Marked the ANSWER as Solved The problem is I am using this in an SDK, I can't have much complex operation for my user. In this approach going back from SDK may want more concentration. As I need all the VC that is opened before I set the SplitVC as root, Because the APP may have tabbarviewController/UINavigation as root that needs to be restored when the app leaves SDK So kindly gave me any other approaches if possible

I have the same issue, did you get any lead.
