SPTPersistentCache is an Objective-C library from Spotify for caching NSData on disk with TTL values and LRU disk-management semantics. It stores each entry as a separate file with a cache header tracking TTL, access frequency, and corruption checks, plus scheduled garbage collection.

Use cases

  • cache images on disk in an iOS app
  • persist downloaded data with a time to live
  • add an LRU disk cache to an iOS or macOS app
  • limit how much disk space cached data uses
  • cache remote files without blocking concurrent reads and writes
  • inspect and strip cache headers from cached files

When to choose

  • you need a battle-tested disk cache for NSData in an iOS or macOS app
  • you want TTL-based expiry and automatic garbage collection of cached files
  • you cache different data types and want separate per-type cache instances

When to avoid

  • you need an in-memory-only cache
  • your app targets platforms beyond iOS/macOS or uses Swift-only tooling without Objective-C interop
  • you need encrypted or compressed caching
