I am facing stranger issue. I have taken UICollectionReusableView for collection view header and set it in collectionView. Its work completely but when I create IBOutlet of UILabel in UICollectionReusableView It always return nil in collection view header method viewForSupplementaryElementOfKind. In XIB file UILabel is successfully connected.

Here is my code.
Register CollectionView Header

collectionView.register(Header.self, forSupplementaryViewOfKind: UICollectionElementKindSectionHeader, withReuseIdentifier: "Header")



func collectionView(_ collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, at indexPath: IndexPath) -> UICollectionReusableView {

      let headerView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "Header", for: indexPath) as! Header

headerView.lblName.text = "Hello" //crash here

return headerView



}

Here its complete demo
