This project is a simple utility to query the biography of any artist. It's meant to showcase basic functionalities and some design principles applied with Swift. To showcase these, some implementations are a bit overkill for this kind of application and arguably violate the KISS principle.
Three principles are showcased in particular. A detailed description of these can be found here.
The project consists out of two products (to use the Swift Package Manager terminology):
- qbio-lib
type=library: Implementation of querying the data. - qbio
type=executable: Simple CLI application that uses qbio-lib for querying the data.
The library provides a protocol ArtistDataSource that can be used to implement custom logic and data sources but with an abstract API.
AudioDBArtistDataSource is an example implementation that uses The AudioDB via an HTTP-API as the data source.
The executable uses qbio-lib to query the biography of one or more artists passed by the user. It's using ArgumentParser by Apple to parse and execute the arguments and options passed by the user.
