An open source iOS framework for WordPress integration using REST/JSON and a custom WordPress plugin. This has been used by several 3rd party consumers to build their own app.
The native mobile app version is available and was inspired from uncovering the joys, pains, and realities of mobile, web, and software development. Many of my blog posts dissect the very same app and other real-world projects. The best part – it is completely open-sourced in Swift!
