The Coordinator Pattern consists of a single class that is responsible for the flow or flows of your application. Typically you will have a root coordinator, who can then use 1 or more sub coordinators as needed. Most of the code is simple instantiation logic, with limited data being passed between view creation methods. With this coordinator you will see a simple but typical implementation, and how we are managing flow within this application.
- [Instructor] We are now ready to start implementing…the coordination pattern within our application.…There's a lot of boilerplate code with the coordinator…so what we've done is we've included a class…within your actual code base.…It's under the Project Files and under the Coordination…there's a file called Root Navigation Coordinator.…We're going to make a group here, we'll call this…Navigation Coordinators.…And we're making an actual group because sometimes…within your application you can have just one coordinator…but it's not uncommon to have many different flows…like a sign-up process or different sections of your app…that you want to be able to navigate to…and they consist of more than one view.…
So sometimes you'll have a root coordinator…and then you'll have a specific coordinator…for those different sections.…And the root coordinator is just in charge of which other…coordinators to trigger or maybe even some single views…to show within there.…So we're going to make an actual group for this.…And we'll just drag and drop it into that group.…
