PINCache is a fast, thread-safe key/value object cache for iOS, tvOS, and macOS, forked from TMCache to eliminate deadlocking. It combines an in-memory cache (PINMemoryCache) with an on-disk cache (PINDiskCache) backed by GCD for safe parallel access from multiple threads.

Use cases

• cache downloaded images offline in an iOS app
• persist expensive computation results between app launches
• avoid deadlocks when accessing a cache from multiple threads
• automatically clear cached objects on memory warnings
• trim disk cache by byte count or age limit
• store NSCoding-conforming objects in memory and on disk

When to choose

• you need a battle-tested Objective-C/Swift cache for Apple platforms
• your app caches downloaded data or slow processing results
• you need thread-safe parallel cache access without deadlocks
• you want automatic memory-warning eviction plus configurable disk limits

When to avoid

• you target non-Apple platforms
• you need a distributed or network-backed cache
• your objects don't conform to NSCoding
• you're building a new Swift-first project and prefer a pure Swift cache
