Flow layout crash on Xcode 6 GM

[guillaumealgis]

I'm getting a crash when testing on the iPad 2 simulator w/ iOS 8, compiled using Xcode 6 GM.
Everything's working fine until I rotate the simulator, then I'm getting this if I started the app in portrait:

Or this if I started in landscape, rotated to portrait, and the came back to landscape again. There's no crash, only Xcode insulting me with "breaking constraints" stuff:

Does anyone experienced the same thing? Is this an Apple bug?

The crash is fixed in Xcode 6.1. Autolayout complains about a lot of broken constraints, though.

@guillaume-algis I ran into the very same problem lately, and I'm using 6.1.1. The feature in iOS 8 still feels a bit shakey and I've actually gone back to basics with regards to doing self-sizing, using a combination of -collectionView:layout:sizeForItemAtIndexPath: on the layout delegate and -systemLayoutSizeFittingSize:UILayoutFittingCompressedSize in the cell itself.
