Flash-Chat

What is Flash Chat

Flash Chat is an internet based messaging app similar to WhatsApp, the popular messaging app that was bought by Facebook for $22 billion. We will be using a service called Firebase Firestore as a backend database to store and retrieve our messages from the cloud.

Important Steps

• Integrate third party libraries in your app using Cocoapods and Swift Package Manager.
• Store data in the cloud using Firebase Firestore.
• Query and sort the Firebase database.
• Use Firebase for user authentication, registration and login.
• Work with UITableViews and how to set their data sources and delegates.
• Create custom views using .xib files to modify native design components.
• Embed View Controllers in a Navigation Controller and understand the navigation stack.
• Create a constants file and use static properties to store Strings and other constants.
• Create animations using loops.
• Learn about the App Lifecycle and how to use viewWillAppear or viewWillDisappear.
• Create direct Segues for navigation.
