I want to load all camera roll videos in UICollectionView along with their duration (same way, the videos are shown in camera roll). How to do so ? I checked this link. But they showed their videos like images.

// get all videos from Photos library you need to import Photos framework
var photos: PHFetchResult<PHAsset>! // user photos array in collectionView for disaplying video thumnail
func getAssetFromPhoto() {
    let options = PHFetchOptions()
    options.sortDescriptors = [ NSSortDescriptor(key: "creationDate", ascending: true) ]
    options.predicate = NSPredicate(format: "mediaType = %d", PHAssetMediaType.video.rawValue)
    photos = PHAsset.fetchAssets(with: options)
    print(photos)
    photoCollectionView.reloadData() // reload your collectionView
}

// For displaying thumnait image and video dutation
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "photoCell", for: indexPath) as! PhotoCollectionViewCell
    let asset = photos!.object(at: indexPath.row)
    let width: CGFloat = 150
    let height: CGFloat = 150
    let size = CGSize(width:width, height:height)
    PHImageManager.default().requestImage(for: asset, targetSize: size, contentMode: PHImageContentMode.aspectFill, options: nil) { (image, userInfo) -> Void in

        self.photoImageView.image = image
        self.lblVideoTime.text = String(format: "%02d:%02d",Int((asset.duration / 60)),Int(asset.duration) % 60)

    }
    return cell
}

I recommend using the photos framework that apple has prebuilt into Xcode. The answer to this question is already filled out here:

swift: How to load photos from photo library without using UIImagePickerController?

The photos framework created by apple:

https://developer.apple.com/library/prerelease/ios//documentation/Photos/Reference/Photos_Framework/index.html

To add a video you can use a UIImagePickerCrollerSourceType: 

picker.sourceType = UIImagePickerControllerSourceType.Camera
