A reduced case to demonstrate a layout issue when using an ASPagerNode with view controller cells.

The view controller in the app wraps an ASPagerNode. The first cell is a normal ASCellNode and functions correctly. All the other cells are GuideRecViewController-wrappers, and their subnodes all have size (0, 0) no matter what I do. If you read the _layout of the GuideRecScrollNode, the frames will be correct, but they do not get applied to the subviews.

Attempted remedies:

• Ensure the constrainedSize values are all correct. They are.

• Remove the GuideRecScrollNode and make GuideRecNode the GuideRecViewController's node directly.

• Manually trigger measurement on the scroll node and also set the contentSize to the size of the measured layout.

• Set preferredFrameSize on the GuideRecNode and its subnodes.

• Use an ASStaticLayoutSpec on the GuideRecNode that lays out one subnode at size (100, 100).

• GuideViewController: ASViewController

  • ASPagerNode
    • ASCellNode
      • GuideRecViewController: ASViewController
        • GuideRecScrollNode: ASScrollNode
          • GuideRecNode: ASDisplayNode
