ios - PageViewController hosted within a Container within a StackView/ScrollView -

i have viewcontroller following hierarchy using xcode 8 , swift 3:

view scrollview stackview container view pageviewcontroller pagecontroll tableview

my intent allow vertical scrolling via scrollview/stackview , working fine.

the container view hosts pageviewcontroller , pagecontrol both of created programmatically vs. storyboard.

my problem can't find way support vertical scrolling of entire page while supporting swiping left/right within pageviewcontroller.

if add pageviewcontroller.view master page via:

self.view.addsubview((self.pageviewcontroller?.view)!)

the swiping between pages in pageviewcontroller works fine upper portion of page doesn't scroll scrollview.

if add pageviewcontroller.view container via:

self.containerview.addsubview((self.pageviewcontroller?.view)!)

while vertical scrolling works fine swiping left , right on pageviews doesn't.

footnote entire viewcontroller hosted within navigationcontroller drill in feed type view.

thanks in advance suggestions.

cheers, mike
