Technical Challenge

Hi, fellow Reviewer,

This document will help you build the project and walk you through into some of the specifics of the project. I hope you’ll enjoy reviewing my code.

Cheers !

Requirements

• Xcode 9.3+
• iOS 11.0+
• Swift 4.0+

Building the project

This project use Cocoapods. Tap the following commands in the root directory

$> sudo gem install cocoapods
$> pod install

It will generate a file MusicPlayer.xcworkspace. Open the project with it (not with MusicPlayer.xcodeproj)

Project Architecture

The architecture evolves around “Stories” where, in the future, whenever the project grows, we can separate different screen logic that represent a new story (ex: Login screens, User Settings screens).

A Story is composed of a Storyboard, ViewControllers, ViewModels and Views directories. This way, it is easy to navigate between classes that are linked inside a same story.

When possible, MVVM is used.

Known issues

• No possibilities to switch forward or backward between songs
• The Apple Music API has a limit when fetching the top charts (limit of 50)

⚠️ The implementation of this project is basic and doesn't handle the token refresh (for the use of Apple Music API). ⚠️

You will have to manually refresh it using the Apple documentation and also this helper to generate the token.

When you get this token, you have to manually place it in the config files :

MusicPlayer -> Supporting Files -> Config -> Development/Debug/Release.xcconfig

replace the value for the key APPLE_MUSIC_KEY

Cocoapods

Two frameworks are used with Cocoapods:

Kingfisher

Really good pod to handle loading and caching of images from urls.

KDEAudioPlayer

AudioPlayer is a wrapper around AVPlayer and also offers cool features.

Testing

To test different parts of the project, I use the Xcode test framework.
