High-speed computation using Accelerate
Many coding problems are designed to perform the same operation on lots of data, and in fact they are so common Apple has a whole framework to make it better: Accelerate. In this video I’ll give you an introduction to Accelerate using practical examples so you can see just how easy it is.

Using memoization to speed up slow functions
In this article you’ll learn how memoization can dramatically boost the performance of slow functions, and how easy Swift makes it thanks to its generics and closures.
