We're going to be implementing a ToDo Capacitor plugin in iOS using Swift. This project is a Capacitor app built with Ionic React, don't worry if you aren't familiar with React there shouldn't be a need to modify the React app although you can add console.log statements or make modifications for debugging purposes.

The relevant areas of the code base are the src directory where the React app code resides.

The ios directory is where the iOS application resides. We'll work specifically in the ios/App/App/ToDoPlugin.swift file to implement the plugin on iOS.

The android directory is where the Android application resides. We'll work specifically in the android/app/src/main/java/io/ionic/crossplatform/interview/TodoPlugin.java file to implement the plugin on Android.
