Capture Video with SwiftUI: A Step-by-Step Guide to Start Recording on Button Click

Are you looking to add video recording functionality to your SwiftUI app? You’re not alone! Many developers want to create applications that allow users to capture video directly from their device's camera. This guide will walk you through how to implement video recording in SwiftUI, specifically focusing on starting the recording with a button click. We will provide a solution to a common issue where developers find that video recording begins automatically when the view opens instead of on demand. Let's dive in!

Problem Overview

When implementing video recording in SwiftUI using the AVCaptureSession, many developers encounter a challenge: starting the recording automatically when the view opens. Instead, what if you want users to have control and start the recording only when they press a button? This is where our solution comes in.

The Requirement

Start video recording from the back camera when a button is clicked, rather than automatically upon view interaction.

Provide an easy-to-follow solution to achieve this functionality.

Solution Breakdown

To effectively capture video using SwiftUI, we will need to structure our code properly. Here’s how to do it step-by-step:

Step 1: Set Up the VideoRecordingView

The VideoRecordingView is key to managing our video output and UI interactions. Below is the updated implementation:

Step 2: Create The PreviewView Class

This class will handle the actual video capturing. Here's how to set it up:

Step 3: Adding Buttons to Control Recording

In your main view, add buttons that users can press to start and stop recording:

Conclusion

By following the setup above, you will be able to implement a video recording feature in your SwiftUI application where recording can be started or stopped using a button click. The design promotes user interaction and gives control over when to record.

With just a few modifications to your code, you can create a smooth and user-friendly experience for recording videos. Now it's time to apply these concepts in your application and watch your ideas come to life! Happy coding!
