// Store string
cache.insert(value, for: key)
// Retrive string
let retrivedValue = cache.value(for: key)
// Remove value
cache.removeValue(for: key)

Cost and count limit

MemoryCache discard a last recently cached value if either cost or count limit is reached.

// Configure cache
let cache = MemoryCache<String>(countLimit: 10, costLimit: .Mbyte(10))
