VIPER is a very clean architecture. It isolates each module from others. So changing or fixing bugs are very easy as you only have to update a specific module. Also for having modular approach VIPER creates a very good environment for unit testing.

• Good for large teams.
• Makes it scalable. Enable developers to simultaneously work on it as seamlessly as possible.
• Makes it easy to add new features.
• Makes it easy to write automated tests since your UI logic is separated from the business logic.
• Makes it easier to track issues via crash reports due to the Single Responsibility Principle.
• Makes the source code cleaner, more compact, and reusable.
• Reduces the number of conflicts within the development team.
• Applies SOLID principles.
• Reduces the number of merge conflicts.

I created a VIPER Xcode template to make the work easier, reduce time for create new files and repeate the same code per module.

To create new module: Create new Group as your module name ---> Add new File --> Scroll down to select VIPER template --> type your module name.

A very lightweight URLSession wrapper to work with REST APIs. Easy to use and flexible with diffirent endpoints, methods.

networkClient.fetch(endPoint: ListUsersEndpoint.fetchListUser(lastId: lastId), type: [User].self) { (result) in
            switch result {
            case .success(let users):
                print("Fetched list users: \(users)")
            case .failure(let error):
                print("Error: \(error)")
            }
        }
