This framework is built using the VIPER (modified to VIPE) architecture. It started as an experiment with the architecture itself and is now a work in progress.

It is a swift wrapper around the AVFoundation framework. Use it to play remote, or local videos in a simple view or feed. Its purpose is to make playing progressive downloads and live streams simpler in your iOS applications

We also wrote a blog post on VIPER itself here:


This framework is a work in progress. Unit tests, VIPE refactoring, and bug fixes are pending.


  • [x] Scrub Video
  • [x] Handle play or stop video in main thread
  • [x] Play in UITableView
  • [x] Autoplay video
  • [x] HTTPS support
  • [x] Written in Swift
  • [x] Landscape support
  • [x] Cocoapod support


  • iOS 10.0 or later
  • Xcode 8.3 or later

Getting Started

  • Go to the "DemoVideoPlaybackKit" folder, run pod install. Open the workspace and build


The VIPER architecture has been talked about in the iOS community; however, it is uncommonly used. We wanted to gain an in depth understanding of this design pattern and see what the buzz was all about. As a result, we decided to test the following hypothesis:

As a developer I would like to use the VIPER design pattern to build reusable modules

We then decided to experiment with VIPER & playing video content. Playing video involves UI updates, data downloading & data syncrhonization. These complexities & interactions proved themselves to be worthwhile candidate for a VIPER structured module.

How To Use

import VideoPlaybackKit

Play a single video in a view - add a single view to your screen which contains video content

  1. Define the Video Type (local or remote). This is the ENTITY represented in the VIPER structure
let videoType = VPKVideoType.local(videoPathName: "Elon_Musk", fileType: "mp4", placeholderImageName: "elon_1")
  1. Build the video view
VPKVideoPlaybackBuilder.vpk_buildVideoView(for: videoType, shouldAutoplay: self.shouldAutoPlay, playbackBarTheme: self.toolBarTheme) { [weak self] (videoView) in

    videoView.snp.makeConstraints({ (make) in


Play a video in a feed

  1. Create a UITabieViewCell that conforms to VPKViewInCellProtocol
class VideoTableViewCell: UITableViewCell, VPKViewInCellProtocol {
    static let identifier = "VideoCell"
    var videoView: VPKVideoView? {
        didSet {

override func prepareForReuse() {
    prepareForVideoReuse() //Extension default


  1. Register cell in UIViewController, set up tableview. Add videoview to cell
    tableView.register(VideoTableViewCell.self, forCellReuseIdentifier: VideoTableViewCell.identifier)
    tableView.estimatedRowHeight = 400
    tableView.rowHeight = UITableViewAutomaticDimension

datasource.asObservable().bind(to: tableView.rx.items(cellIdentifier: VideoTableViewCell.identifier)) { index, model, cell in

    guard let cell = cell as? VideoTableViewCell else { return }

    VPKVideoPlaybackBuilder.vpk_buildViewInCell(for: model, at: NSIndexPath(item: index, section: 0), completion: { [weak self] (videoView) in
            cell.videoView = videoView



Autoplay Videos in a feed

  1. Conform to the VPKTableViewVideoPlaybackScrollable protocol

Implement the following:

extension FeedViewController: VPKTableViewVideoPlaybackScrollable {

func scrollViewDidScroll(_ scrollView: UIScrollView) {
    handleAutoplayInTopVideoCell() // default implementation
    trackVideoViewCellScrolling() // default implementation

func scrollViewDidEndDecelerating(_ scrollView: UIScrollView) {
    if shouldAutoplayVideos {


Play video in feed, pre-fetch video asset data. *** Recommended especially for auto playing video in a feed ***

  1. Create a VPKTableViewPrefetchSynchronizer object
videoPrefetcher = VPKTableViewPrefetchSynchronizer(videoItems: datasource.value)
  1. Conform to the UITableViewDataSourcePrefetching tableview protocool
tableView.prefetchDataSource = self

extension FeedViewController: UITableViewDataSourcePrefetching {

func tableView(_ tableView: UITableView, prefetchRowsAt indexPaths: [IndexPath]) {
    videoPrefetcher?.tableView(tableView, prefetchRowsAt: indexPaths)

func tableView(_ tableView: UITableView, cancelPrefetchingForRowsAt indexPaths: [IndexPath]) {
    videoPrefetcher?.tableView(tableView, cancelPrefetchingForRowsAt: indexPaths)
