A sample iOS app with REST API calls. Using RealmDB for caching. All code in Swift. Custom made networking for data fetching.

Nimbus for iOS

Nimbus is a reference application, a compendium of several techniques and architectural implementations in a test use-case on the iOS platform.

Simply put, the app:

• Fetches data from the internet through an API (json),
• Parses the data into objects to be used in the app,
• Stores the data in a Realm DB,
• Queries and retrieves data to display in the User Interface.

This reference app is making use of:

• Initially started as an Obj-C project, now it has moved to Swift (there are a few Obj-C grains here and there),
• Uses Cocoa Pods for necessary third-party SDKs and APIs (do a pod install after cloning -- not all code is commited due to GitHub space limits),
• Implements Realm DB to store data. Originally Core Data were used but Realm came as a replacement due to it's interoperability (see Android) and ease of use,
• A custom Network Wrapper updated for iOS 15+ with async/await (though it's not complete to handle all network connections and calls)
• Loose MVVM architecture (Don't expect to see codexes, canons and gospels here. I use what I see fit on a simple app such as this)
• UIKit. Chneck the SwiftUI branch for... well, SwiftUI (still under development)
