In Swift, the “protocol can then be adopted by a class, structure [a struct], or enumeration [an enum] to provide an actual implementation of those requirements.... » read more
In this article, I will briefly explore Stacks and Queues. We will also look at how we can implement these data-structures in Swift, and furthermore we’ll look at the types of applications which we can use stacks and queues for. As an aside, you will often hear stacks referenced in the context of memory management,... » read more
