Functional Swift to the rescue:

“Dealing with Optional values (specifically Implicitly Unwrapped Optionals) is unfortunately an everyday part of our life as forward-looking iOS developers.

“It includes a zero-config image cache with automatic resizing. Everything is done in background, allowing for fast, responsive scrolling.”
