This is how i configured the collectionview the library crashes on Crash on ADMozaikLayoutSectionMatrixError.rowOutOfBounds

Hi @Rico9260 thanks for reporting it, I will check it soon.

Hi, @Rico9260 could you report please what device or simulator did you use to get a crash? So far I can not reproduce the crash. Do you have any other information that may help?

[rajatkj]

I have tried all Devices and Simulators. I have configured CollectionView inside a Tableviewcell.

@Rico9260 are you able to provide a sample project that crashes?
