MemoryCache

What is MemoryCache?

MemoryCache is a memory cache class in swift.

• The MemoryCache class incorporates LRU policies, which ensure that a cache doesn’t use too much of the system’s memory. If memory is needed by other applications, it removes some items from the cache, minimizing its memory footprint.
• You can add, remove, and query items with expiration in the cache from different threads without having to lock the cache yourself. ( thread-safe )
• Unlike the NSCache class, the cache guarantees a type by its key. ( type-safe )
