UICollectionview header implementation iOS swift

 Problem:

I want to add header like tableview view to show the title of the section in UICollectionview iOS swift

Solution:

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, referenceSizeForHeaderInSection section: Int) -> CGSize {

        let indexPath = IndexPath(row: 0, section: section)

        let headerView = self.collectionView(collectionView, viewForSupplementaryElementOfKind: UICollectionView.elementKindSectionHeader, at: indexPath)

        

        return headerView.systemLayoutSizeFitting(CGSize(width: collectionView.frame.width, height: UIView.layoutFittingExpandedSize.height),

                                                  withHorizontalFittingPriority: .required, // Width is fixed

                                                  verticalFittingPriority: .fittingSizeLevel)

    }

    

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

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

        

        switch kind {

        case UICollectionView.elementKindSectionHeader:

                headerView.title.text = "header"

            

            return headerView

            

        default:

            assert(false, "Unexpected element kind")

        }

        

        return headerView

    }
