How to make both header and footer in collection view with swift

You can make an UICollectionViewController to handle the UICollectionView and in Interface Builder activate the Footer and Header sections, then you can use the following method for preview in you UICollectionView the two sections added :

override func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView {
    
    switch kind {
        
    case UICollectionView.elementKindSectionHeader:
        
        let headerView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "Header", for: indexPath)
        
        headerView.backgroundColor = UIColor.blue
        return headerView
        
    case UICollectionView.elementKindSectionFooter:
        let footerView = collectionView.dequeueReusableSupplementaryView(ofKind: kind, withReuseIdentifier: "Footer", for: indexPath)
        
        footerView.backgroundColor = UIColor.green
        return footerView
        
    default:
        
        assert(false, "Unexpected element kind")
    }
}

In the above code I put the identifier for the footer and header as Header and Footer for example, you can do it as you want. If you want to create a custom header or footer then you need to create a subclass of UICollectionReusableView for each and customize it as you want.

You can register your custom footer and header classes in Interface Builder or in code with:

registerClass(myFooterViewClass, forSupplementaryViewOfKind: UICollectionElementKindSectionFooter, withReuseIdentifier: "myFooterView")
