Streamlining AVPlayer Usage Across Multiple View Controllers in Swift

Integrating audio playback functionality into your iOS application can be a daunting task, especially as it grows more complex. Perhaps you're developing a radio app that streams live audio, and you've reached a point where repeated code in multiple view controllers is hindering your progress. How can you avoid this redundancy while maintaining a clear and efficient architecture? The answer lies in creating a reusable Swift class, specifically for AVPlayer.

In this guide, we will explore how to build a UniversalAVPlayer class that simplifies audio management and allows you to maintain clean code as you create additional view controllers.

Why Use a Custom Class for AVPlayer?

When you're working with audio playback, particularly with AVPlayer, you may not need all the functionalities of the standard class. By creating a custom class, you can:

Encapsulate functionality: Keep all audio-related methods in one location, reducing clutter in your view controllers.

Promote code reuse: Use the same class across multiple view controllers to handle playback without duplicating code.

Enhance maintainability: Update your audio logic in one place if your app evolves.

Building the UniversalAVPlayer Class

Let's go step-by-step to create the UniversalAVPlayer class that will handle all your playback needs.

Step 1: Class Declaration

First, declare the UniversalAVPlayer class and add necessary properties:

Here, we have a variable player to hold the AVPlayer instance and an initializer that accepts a URL for the audio stream.

Step 2: Configuring the Player

You need to configure the audio session and prepare the AVPlayer for playback:

Conclusion

By creating a UniversalAVPlayer class, you facilitate a robust architecture that allows for efficient audio management throughout your application. This approach not only keeps your view controllers clean but also enables you to effortlessly maintain and expand your audio functionalities in future updates.

Final Thoughts

As you continue developing features like remote commands or user controls, remember to centralize your logic in the UniversalAVPlayer, making your app scalable and maintainable.

With this guide, you now have all the tools you need to enhance your Swift applications with streamlined audio playback functionality. Happy coding!
