.append function vs. += : What is the difference?

Hello,

Im working through Swift basics and I came across the += for adding items to an array and then I learned about the .append function. Is there a difference? When would I use += vs. .append? Maybe it is just the context and I am to early in the process to see it clearly.

It may be a little early in the process to have a good grasp on the differences. The main one in my mind is that += lets you add multiple new items at the same time. append only lets you add one new item at a time, so you'd have to call it multiple times in a row to get the same effect as +=.
