## What it is
DefaultsKit is a lightweight Swift library providing a strongly typed, Codable-based wrapper around UserDefaults for iOS, macOS, and tvOS. It lets developers store and retrieve values, including complex Codable objects, using type-safe keys in under 100 lines of code.

## Use cases
- store user preferences with type-safe keys in swift
- persist codable structs to userdefaults
- save and read settings on ios and macos apps
- avoid stringly-typed userdefaults keys
- check if a defaults key exists without deserializing
- wrap userdefaults for tvos apps

## When to choose
- you want a minimal, strongly typed UserDefaults wrapper in Swift
- you need to persist Codable structs or classes to user defaults
- you prefer lightweight libraries with few dependencies

## When to avoid
- you need large-scale persistence like a database or file storage
- you want reactive/observable preference bindings
- you target platforms outside Apple's ecosystem

## Facets
- artifact type: library
- maturity: stable
- function: serialization, developer-tools
- domain: developer-tools, mobile-development, cross-platform
- platform: -
- tags: userdefaults, codable, key-value-storage, swift-package, preferences, ios, macos, swift
