Swift's operator: what is the different between ++i and i++?

I'm confusing. In Swift 2.0 course (operator section), teacher said always use ++i but (in while loop section) he uses i++ for while loop. Or I'm missing anything? thank you.

They are different. Here's an article that reviews the difference, and proposes their removal from the next version of Swift -- a proposal that has been accepted.
