TabBar with Coordinator

Example iOS app demonstrating how to use a UITabBar with the iOS Coordinator pattern.

There are many ways of implementing a Coordinator in your app. My preferred way of doing the Coordinator pattern at the moment is with this library which this project uses.

This project is meant to demonstrate 1 thing: how to show a UITabBar in your app where each screen of the tab hosts a child coordinator.

Here is an overview on how to do this:

1. (link to source) Create a main coordinator the the AppDelegate starts and shows the first ViewController of the app. Since UITabBarController is a UIViewController, our TabBar will be our ViewController this coordinator starts.
2. (link to source) Have your UITabBarController instantiate a child coordinator for each tab. The ViewControllers of our UITabBarController are the root ViewControllers of each of these coordinators.
3. Done! The rest of the implementation of this app demonstrate the coordinator pattern more then how to use coordinators with a tab bar.

Getting started

• Clone the repo to your machine.
• pod install
• Open workspace on your machine. Compile and run app.

Credits

Inspiration for this project comes from this doc that gave me the idea of referencing the ViewControllers within each child coordinator. Thanks!
