## What it is
AwesomeCache is a Swift library providing a thread-safe on-disk cache for Apple platforms, backed by NSCache for fast in-memory access with automatic disk persistence. It supports per-object expiry (by seconds or date), expired-object cleanup, and a cacheBlock helper for caching async API responses.

## Use cases
- cache API responses on disk in an iOS app
- persistent disk cache for Swift objects with expiry
- store downloaded data locally with a TTL in Swift
- thread-safe in-memory plus disk cache for iOS
- cache-aside wrapper for async network calls in Swift

## When to choose
- You are building an iOS, watchOS, or tvOS app in Swift and need simple persistent caching with per-object expiration
- You want NSCache-backed memory performance with disk persistence as a fallback
- You want a small, sync API to cache results of async tasks such as network requests

## When to avoid
- You target non-Apple platforms such as Linux or Android, since it depends on NSCache and Apple frameworks
- You need an async or modern-Swift-first API, as the library was built around the Swift 3 era and its last release was in 2021
- You need large-scale or queryable storage, where a database or dedicated cache server is a better fit
