This app is part of Angela Yu's iOS Development Course, here's what I learned:

• Custom TableView for messages
• Using Cocoapods packages for implementing features like animated welcome screen
• Firebase Authentication for registration and logging the user in
• Storing and retrieving messages data in Firebase Firestore
• The ViewController Lifecycle and App Lifecycle

I also improved upon the app by adding features of my own:

• Clear messages history button
• Playing sound when sending and receiving a message
