TheMovieDB

Using open API of themoviedb.org

Discover

• Show list of the popular movies using discovery.
• When I scroll to the bottom of the list, then the next page should load if available

Search screen

• When one enters a name of a movie (e.g., "Batman," "Rocky") in the search box and tap on "search" button, then I should see a new list of movies.
• When one taps and focus into the search box, hen an auto-suggest list view will display below the search box showing their last ten successful queries (exclude suggestions that return errors)
• When I select a suggestion, then the search results of the suggestion will be shown.
• When I scroll to the bottom of the list, then the next page should load if available
• Suggestions should be persisted.

Details screen

• when tap on the movie on any list the details screen should be shown.

The Movie cell and detail screen should consist of:

• Movie Poster
• Movie name
• Release date
• Full Movie Overview

Run

To run please open TheMovieDB.xcworkspace chose device or simulator and run. I've kept Pods directory to remove the hassle with pod installation etc.

General Architectural Approach

a.k.a. what's good about this solution

I have chosen a MVVM approach with the coordinators and my tiny Observable wrapper for binding.

Good

• both of the screens consist of movies list, so I wrote it once Presentation/Movies List.
• Models of these screens are also different only that search model contains the query, so it was also a good candidate for reuse.
• Inversion of URLSession allows me to test any depending service with ease.
• the design is pretty nice and follows last apple guidelines.

Might be improved

• The suggestion model made pretty weak and might be developed in the better way and also should be tested.
• Also, some cool transition might be added.
• Collection view instead of table view would give much more flexibility.
• Naming of course always might be improved.

Project structure

├── Source    # all the source code
├── Tests     # tests
├── Resources # plist and resources
└── Pods      # to make building and running easier

The Source folder consists of:

I structure the code by layers, so each layer represented by folder and each subfolder is an entity of that layer.

Application

Application layer AppDelegate etc. Usually, here I create Dependency Container and the main router (coordinator) to coordinate screen presentation and injecting dependencies into the services and screens.

Domain

Domain layer consists of structures that can be used everywhere in the application such as Movie as these entities are the part of the knowledge domain, so-called objects from the real world.

Presentation

Presentation layer only consists of Views (screens) and their View models.

Services

Service layer contains all services, classes that do work (usually in the background) and provide data to the application. Here are only API and Storage.
