This interface defines few simple steps:
- store the module route, so it can be accessed many times
- route the request sent to the module with parameters to desired functionality which is encapsulated in the module

var route: String { get set }
init(route: String)

View Module.swift
public typealias ModuleParameters = [String: String]
Application module represents a group off all the classes that implement a certain functionality of the module, like:
- Storyboard
- View Controllers
- Views, specific to the module
- Presenters, View Models and other Client architecture classes
- ...
View ApplicationRouter.swift
public typealias ModuleCallback = ([String: Any]?, Data?, URLResponse?, Error?) -> Void
Protocol defines application router, which function is
- register application modules
- access/open the modules
- provide the callback, result of the access
protocol ApplicationRouterType: class {
You can’t perform that action at this time.
