![]() You can easily download hereĭrag and drop Get Start folder and implement in AppDelegate didFinishLaunchingWithOptions /// Show starter I have created a GitHub Repository for Starter. Starter is used to show major 3 features at center of the screen. So, I just develop like a feature list screen. Most of the apple native apps was showing major features list at first time of application opened. A setup function that styles the capture button appropriately.Here I developed a feature list viewController like Apple native apps.A computed property to hide the status bar.All of the necessary outlets that connect the UI controls mentioned above to our code.A ViewController.swift file that’s responsible for managing the view controller mentioned above.The necessary controls for switching cameras and toggling the flash.A capture preview view so that you can see what the camera sees in real time.A capture button to initiate photo / video capture.This view controller will be used to handle all photo and video capture within our app. A Storyboard file with one view controller. ![]() You can find them, along with hundreds of others, available for free at material.io/icons. Credit goes to Google’s Material Design team for these icons. An Assets.xcassets file that contains all of the necessary iconography for our project. ![]() Before you move on, download the starter project here and take a quick look. You’ll work on an example project, but to let us focus on the discussion of the AVFoundation framework, this tutorial comes with a starter project. Here’s a diagram that I made that depicts this relation:Īs always, we want you to explore the framework by getting your hands dirty. To use AVFoundation, you take capture devices, use them to create capture inputs, provide the session with these inputs, and then save the result in capture outputs. According to Apple, the capture session is “an object that manages capture activity and coordinates the flow of data from input devices to capture outputs.” In AV Foundation, capture sessions are managed by the AVCaptureSession object.Īdditionally, the capture device is used to actually access the physical audio and video capture devices available on an iOS device. Sessions, Devices, Inputs, and OutputsĪt the core of capturing photos and videos with AV Foundation is the capture session. Make sure you actually need to use AV Foundation before you begin this tutorial. In many instances, using Apple’s default APIs such as UIImagePickerController will suffice. Do I need AV Foundation?īefore you embark on this journey, remember that AV Foundation is a complex and intricate tool. In this tutorial, we’ll specifically be using it to capture photos and videos, complete with multiple camera support, front and rear flash, and audio for videos. AV Foundation is a framework for capturing, processing, and editing audio and video on Apple devices. Using AV Foundation, you can easily play, create, and edit QuickTime movies and MPEG-4 files, play HLS streams, and build powerful media functionality into your apps. What is AV Foundation?ĪV Foundation is the full featured framework for working with time-based audiovisual media on iOS, macOS, watchOS and tvOS. ![]() This tutorial also assumes that you have a relatively strong knowledge of basic UIKit concepts such as actions, Interface Builder, and Storyboards, along with a working knowledge of Swift. You won’t be able to run the demo app on the simulator. Note: This tutorial requires a physical iOS device, not the simulator.
