HI,

I got block by this issue. if you simply add a reload line to in didSelectItemAt and then run the project. by scrolling to the bottom and getting back to the top. if you tap on mid-cells app will crash.

here is the error:

When i make this example to support all orientation, while moving from portratoit to landscappre or vice versa the app crashes with below error,
SCSectionBackground[34266:300939] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'layout attributes for supplementary item at index path (<NSIndexPath: 0x6000028aa600> {length = 2, path = 0 - 0}) changed from <SCSectionBackground.SCSBCollectionViewLayoutAttributes: 0x7ff023717780> index path: (<NSIndexPath: 0x6000028a9220> {length = 2, path = 0 - 0}); element kind: (sectionBackground); frame = (0 0; 667 116); zIndex = -1; to <SCSectionBackground.SCSBCollectionViewLayoutAttributes: 0x7ff023700110> index path: (<NSIndexPath: 0x6000028aa600> {length = 2, path = 0 - 0}); element kind: (sectionBackground); frame = (0 0; 375 116); zIndex = -1; without invalidating the layout'

Could you help to resolve this ?
