## What it is
The open-source Kickstarter iOS mobile application, written in Swift with ReactiveSwift and a functional reactive architecture. It serves as a real-world reference for building a production iOS app with view models, snapshot testing, and localization.

## Use cases
- study how a production iOS app is architected
- learn functional reactive programming in Swift
- see snapshot testing of localized UI screens
- build a crowdfunding app for iOS
- explore view model patterns isolating side effects
- reference for open-sourcing a native mobile app

## When to choose
- you want a large, real-world Swift codebase demonstrating FRP and view models
- you're building an iOS app and want architectural reference patterns
- you want to see snapshot testing and localization testing at scale

## When to avoid
- you need a reusable library or framework rather than a full app
- you target Android only (see kickstarter/android-oss instead)
- you want a minimal starter template rather than a mature production codebase
