ByteCast #5 - Generic Cache + Expiration Timestamp | NSCache | Swift

In this 5th episode, we’re going to create a generic Swift Cache that can be used to cache value for any Swift type with optional date expiration timestamp support. We will be using NSCache, which is an in-memory based cache Apple provides to temporarily store key and value pairs that are subject to eviction when system’s memory is low.
This cache can be used to store transient values which might be expensive to calculate or retrieve. We can reuse the object without recalculation to improve app performance and it can be discarded when memory is tight.
It’s also thread-safe which means we can mutate from different threads without having to implement locking mechanism
