![]() ![]() ![]() This course is for intermediate iOS developers who are comfortable with the Swift language, SwiftUI and know their way around Xcode. Take several videos and merge them into a singular video that you can save to your phone. Learn how to take several video sources and produce a merge preview of them. Unlock the video camera on your phone and then learn how to access your recordings in your code. Learn how to take pictures with AVFoundation and then how to control the flash on demand. Use AVFoundation to access the camera and show a live preview on the screen. Understand how to add picture-in-picture capability to your app so your users can watch your video in a small floating window. Learn how to create a list of videos and then play those videos one after another using an AVPlayerViewController. Learn how to incorporate video playing in your SwiftUI app. Leverage the AVAssetImageGenerator to produce thumbnails for each of your videos. Get started with working with videos by importing videos into your app by way of the PHPickerViewController. ![]() Learn how to import videos, create thumbnails from them, play live videos in SwiftUI, setup capture sessions to preview and capture still images, record movies files and merge multiple video clips. This course covers the essentials to using the AVFoundation framework to create video based apps. Once we fully implement the code, what we will get is a single free function such that, when called, will compress a single video file with a given configuration and notify us for success or error with callbacks. The resulting code will work on iOS 9 and greater. Genre: eLearning | Language: English | Skill Level: IntermediateĪVFoundation is Apple's advanced framework for working with time-based media, such as audio and video. Native AVFoundation Framework includes all the tools we need. Line 54 : Here we are just creating a function to stop the recording and converting that recording variable as false. Line 46 : When we started our recording successfully, then we are doing true that variable. You can find that function in extension folder in project repository. We are using a function call to fetch the current date into string. Notice the last words “.m4a” is really important to give. Line 30 : We have to give a unique name to every recording file, so we are giving the name as current date and time. Line 29 : The path will contain the directory of the recording. Line 19 : Creating the start recording function and doing some formalities, but there are some lines to understand are as follow. The apps Documents directory (at the path you posted) is the typical place for files like this. Line 14 : We are initialising and we will call a function here letter. You can find that in Model folder in project repositry. Line 11 : We are creating an Array to store our URL of recordings and some details, and the type of that array is Recording. Line 9 : We are creating a variable to check if recording has started, we will need it while playing with UI. Now the first feature we are going to implement is to start & stop recording feature : Then created audioRecorder and audioPlayer, two variables of type AVAudioRecorder! and AVAudioPlayer!. Imported AVFoundation and created a class as VoiceViewModel of type ObservableObject. Our view model is so reactive in nature so that UI can observe it easly. The first thing that we are going to see is our view model. Note : Make sure to open final project and compare the following code with projects code. Views : Our view folder will contain the views in swiftUI for our app ViewModels : It will contain the our all view models Models : Here we will create some model for recording Extensions : It will have some extensions First Step in Our Project Now lets understand the naming of folders we have created. Now open the project and take a look then come back here. What do you think about name ? let me know on my social links given last in this article. ![]() Line 9 : We are iterating over the our recording list and checking if the audio is playing, if playing then stop it the check if it is the recording we want to delete. Line 4 : In this line, we are deleting that recording. Lets give a good name to our project, I decided a name as “ CO-Voice”. Line 1 : To delete the recording from the system, we need their url. There are lots of INBuilds, try to explore more about it.Recordings directory stores in system in urls form and URL type.The best way to understand the AVFoundation or anything is by just doing that in practical :) Key Points for AVFoundation But in this project we will handle and use the recording and playing feature only. AVFoundation is an extremely large framework, we can do a lot with it. ![]()
