Error: UICollectionView received layout attributes for a cell with an index path that does not exist in Swift

There is prepare function in PinterestLayout.swift as it should be because it is the only layout used for customizing the collectionView.

At line 76, in PinterestLayout.swift file.

Try

override public func prepare() {
    cache.removeAll()
    if cache.isEmpty {
       .....
    }
}

extension UICollectionView{
   func refreshLayout() {
        let oldLayout = collectionViewLayout as! UICollectionViewFlowLayout
        let newLayout = UICollectionViewFlowLayout()
        newLayout.estimatedItemSize = oldLayout.estimatedItemSize
        newLayout.footerReferenceSize = oldLayout.footerReferenceSize
        newLayout.headerReferenceSize = oldLayout.headerReferenceSize
        newLayout.itemSize = oldLayout.itemSize
        newLayout.minimumInteritemSpacing = oldLayout.minimumInteritemSpacing
        newLayout.minimumLineSpacing = oldLayout.minimumLineSpacing
        newLayout.scrollDirection = oldLayout.scrollDirection
        newLayout.sectionFootersPinToVisibleBounds = oldLayout.sectionFootersPinToVisibleBounds
        newLayout.sectionHeadersPinToVisibleBounds = oldLayout.sectionHeadersPinToVisibleBounds
        newLayout.sectionInset = oldLayout.sectionInset
        newLayout.sectionInsetReference = oldLayout.sectionInsetReference
        collectionViewLayout = newLayout
    }
  }

Then call:

YourCollectionView.refreshLayout()
YourCollectionView.reloadData()

Happy Coding!

Received this error when I was accidentally setting a collectionView cell's height to 0. Make sure height (or any dimension) is greater than 0! Making sure it was always greater than 0 solved the issue for me.
