Assertion failure in UIQueuingScrollView didScrollWithAnimation:force:

Question

I\'ve got a UIPageViewController set up paging my ImageViewController.

The ImageViewController contains a UIScrollView

Answer 1

It surely looks like a bug in iOS 8 and 9. (and the "answers" down below attempt to work around that)

Feel free to file a ticket on bugreport.apple.com Do be sure to specify how to crash PhotoScroller

Include all iOS versions you've seen it crash on

To date I've seen:

Assertion failure in -[XXX.TrackingPageViewController queuingScrollView:didEndManualScroll:toRevealView:direction:animated:didFinish:didComplete:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3512.60.12/UIPageViewController.m:2028

Assertion failure in -[_UIQueuingScrollView _didScrollWithAnimation:force:], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3512.60.12/_UIQueuingScrollView.m:785 (lldb)

I'll keep the list updated (Despite the downvoting, however massive). Stay tuned.

It does not look like our bug.

UPD 2016 09 27 (on Xcode 8 now):

Assertion failure in -[XXX.TrackingPageViewController queuingScrollView:didEndManualScroll:toRevealView:direction:animated:didFinish:didComplete:], /SourceCache/UIKit/UIKit-3347.44.2.2/UIPageViewController.m:1875
