Write code in Swift programming language. Don't include usage examples or tests.
Generic in-memory cache that follows to the LRU (Least Recently Used) eviction policy.
The cache should have a specified capacity limit, and when this limit is reached, it should remove the least recently used item to make space for new entries.<end_of_turn>

Generic in-memory cache that follows to the LRU (Least Recently Used) eviction policy.
The cache should have a specified capacity limit, and when this limit is reached, it should remove the least recently used item to make space for new entries.<end_of_turn>
