## What it is
GroundControl is an Objective-C library for iOS that enables remote configuration of apps by fetching a plist file over HTTP and registering it with NSUserDefaults. It supports feature flags, A/B testing, and remote settings without downloading new code.

## Use cases
- remotely configure ios app settings
- add feature flags to an ios app
- run a/b tests without app store release
- show a remote message of the day in my app
- fetch remote defaults plist into nsuserdefaults

## When to choose
- you maintain a legacy Objective-C iOS app needing simple remote config via a static plist endpoint
- you want a minimal NSUserDefaults-based feature flag mechanism

## When to avoid
- you are starting a new project - the library is explicitly unmaintained since 2021
- you need a full-featured remote config service with targeting, rollout, or analytics
- your project is written in Swift or uses modern tooling

## Facets
