Parse, the mobile app platform, has one particularly interesting product: Parse Core. One of its features allows app developers to store data in the cloud, without worrying about setting up servers and designing a REST API. Parse Core is also locally backed, like Core Data, which makes it a very good solution for online-offline back-ends.
This tutorial explains how to create an app that’s backed by Parse. We’ll create an Instagram-like app with these features:
- Load data from Parse, store it locally.
- Save data to Parse, write it back to the cloud.
- Upvote, or like, pictures of cats.
The app will be entirely created with Swift, Apple’s new programming language for making iOS apps. Parse isn’t yet rewritten in Swift, so we’ll have to create a Bridging Header to work with it.
This is what you’ll learn:
- Working with Parse, retrieving and saving data in the cloud.
- Integrating a Swift project with Objective-C frameworks, with Cocoapods.
- Setting up views and a custom table view cell with Interface Builder.
- Coding an entire app with Swift, from scratch.
- Working with Auto Layout and constraints.
- Using gesture recognizers, optionals, conditions, closures, properties, outlets and actions.
