What if I want to build for iOS?

As I don't have the necessary equipment, I cannot test the build process for iOS.

You might need to make some adjustments to the app for iOS compatibility.

Conclusion

By customizing the development process, you can add various features to the application as needed.

This concludes the Android development and build process.
