Exporter

Problem

Lets say you have instances of two data types, Comment and Annotation, that need to get saved to a Remote Store of some type.

Assumptions

1. Comment object has two properties named as userid and message.
2. Annotation object has four properties names userId, color, image and message.
3. RPFirebase / RPGraphQL servers need unique app name, unique app id and unique app path from the app to initialize the server.

The above two objects (Comment / Annotation) need to get saved to a remote servers RPFirebase/RPGraphQL (not real Firebase/GraphQL).

Goal

Create a framework, which help us to send/export message (comment/annotation) to a remote server and integrate the framework into a main project. We can add this framework into all the project which has same requirement.

Framework must have the following capabilities:

1. Framework can be used in multiple projects so we should not keep any credentials inside framework relates one project. Main project should have a capability to pass the credentials to framework and framework should work based on what it gets from the project.
2. Flexibility to change from the existing server to a new server without changing the architecture.
3. Capability to add a new server with minimal changes.
4. Capabillity to add a new message type (like comment/annotation) without updating pattern.

Solution

Created a framework with all the above capabilities.

https://github.com/balasaida/MessageExporter

Added a framework into the project

https://github.com/balasaida/Exporter/tree/develop

MyExporter project demonstrates how to use the MyMessageExporter framework and helps you to understand the framework better.

Requirements

• iOS 12.0+ | macOS 10.15.5+
• Xcode 11.3.1

Usage

To add the framework to your project. You should do

carthage update
