611 Points++ operation being removed in Swift 3.
During this lesson, it says to use ++ to increase the value of something by 1. But Swift notified me it is being removed in Swift 3, which would result in this portion of the video needing to be changed upon release of Swift 3.

Courses Plus Student 7,653 PointsApple has removed the ++ and made it much simpler with the another old traditional way.
Instead of ++, you need to write +=.
Example:
var x = 1
//Increment
x += 1 //Means x = x + 1 Similarly for decrement operator --, you need to write -=

Andrew Doumith
1,392 PointsActually... XCode says that += is not a valid prefix unary operator.

2,370 Pointsyes that's correct. You can see some upcoming changes here: http://ericasadun.com/2015/12/03/changing-swift-whats-coming-up-in-2-2-and-3-0/ I think it's best to ignore any depreciation messages for now.
