Swift Package Manager

Add package into Xcode Project settings -> Swift Packages


pod 'DTCollectionViewManager', '~> 10.0.0'

Quick start

Let's say you have an array of Posts you want to display in UICollectionView. To quickly show them using DTCollectionViewManager, here's what you need to do:

  1. Create UICollectionViewCell subclass, let's say PostCell and adopt ModelTransfer protocol:
class PostCell : UICollectionViewCell, ModelTransfer {
    func update(with model: Post) {
        // Fill your cell with actual data
  1. In your view controller:
class PostsViewController: UICollectionViewController, DTCollectionViewManageable {

    override func viewDidLoad() {

        // Register PostCell to be used with this controller's collection view

        // Populate datasource

Make sure your UICollectionView outlet is wired to your class (or use UICollectionViewController subclass). If you have a PostCell.xib file, it will be automatically used for dequeueing PostCell.

  1. That's it! It's that easy!

Of course, cool stuff does not stop there, framework supports all datasource and delegate methods as closures, conditional mappings and much much more! Choose what interests you in the next section of readme.

Burning questions

Release Notes

29 weeks ago


  • Wrappers for collectionView:selectionFollowsFocusForItemAtIndexPath: delegate method.
  • Wrappers for iOS 15 UICollectionViewDelegate.collectionView(_:targetIndexPathForMoveOfItemFromOriginalIndexPath:atCurrentIndexPath:toProposedIndexPath:) delegate method.


  • Wrappers for collectionView:willCommitMenuWithAnimator delegate method, that was only briefly available in Xcode 12, and was removed by Apple in one of Xcode 12 releases.


  • To align version numbers between DTModelStorage, DTTableViewManager and DTCollectionViewManager, DTCollectionViewManager will not have 9.x release, instead it's being released as 10.x.


  • targetIndexPathForMovingItem deprecated on iOS / tvOS 15 and higher, because delegate method collectionView:targetIndexPathForMoveFromItemAt:toProposedIndexPath: was deprecated in favor of newer method.
