What I found is ?
Try to scroll horizontally between the interface controllers inside a root page controller.
- Randomly after a while (30-1 min).
- You will find that one of the interface controllers gets missing.
- Blank view is shown, UI disappears completely. ( Black view with no interface ).
- Try to open the view debugger in XCode, you will find that the Interface window of the view is missing from the page view controller hierarchy.
To reproduce
- Create a new application.
- Create a new Watch application
- Added 2 additional interface controllers to the storyboards
- Add Identifier for both
- Inside the initial interface controller call
WKInterfaceController.reloadRootPageControllers(withNames: ["View1","View2"], contexts: ["View1","View2"], orientation: .horizontal, pageIndex: 1)
- Run the application on Watch OS 6 Series 3 ( Simulator or A device )
- Try to scroll randomly
What I expect from the Page controller to hold the interface controllers as it should and it shouldn't show a blank black screen, while the user is scrolling.
