Can you provide an example of how to use it? I don't seem to know how to use it. #7

   So, here's an example:

   // main.swift
   
   let imageCache = MemoryCache<NSData>(countLimit: 50, automaticallyRemoveAllObjects: true)
   
   func imageApiCall(key: String, completion: @escaping (NSData) -> ()) {
       // some expensive code
   }
   
   func fetchImage(key: String, completion: @escaping (NSData) -> ()) {
       imageCache.get(key: key) { cachedData in
           if let data = cachedData {
               completion(data)
           } else {
               imageApiCall(key: key) { requestedData in 
                   imageCache.set(key: key, value: requestedData)
                   completion(requestedData)
               }
           }
       }
   }

   P.S Here's a class that lets you cache a wider range of objects.

   Also, the author is pretty great. Check out this iOS related podcast he did a while back.
