Crash in CollectionView.swift on line 153
Hi @HamzaGhazouani,
I have noticed a strange crash that sometimes happens when switching between data sources. I cannot provide the exact steps on how to reproduce the issue, but I am sending you a stacktrace that might be of help. I also know (by setting an Exception breakpoint) that the crash occurs in the CollectionView.swift file on line 153.
Please take a look and let me know your findings.

Looking forward to hearing from you and once again, thanks for this awesome library!
Cheers, Sasho
I have also noticed the same crash, hope this will be addressed at earliest.
Thanks Sam
Hi guys,
For me, removing the line collectionViewLayout = placeholderLayout or changing it to collectionViewLayout = defaultLayout fixed the issue, without affecting the collection view layout in any way.
@HamzaGhazouani, please investigate this when you can :)
Thanks!
Hi Guys, Thanks for your feed back, I will look at it as soon as possible If you have any suggestion or a fix, please, don't hesitate to send a PR
