I have a parent PageViewController and a child UIViewController.
Here's my intended behavior:
If user pans horizontally, turn the page to the next or previous UIViewController.
If user pans vertically, do the intended action within the UIViewController.
Right now the PanGestureRecognizer in the UIViewController intercepts all gestures, making it impossible to turn the page.
How can I conditionally intercept pan gestures that are horizontal?
