iOS Swift 2.0 Basics Swift Operators Unary Operators

Unary Operators 3 mins in ++levelScore is no go!!

Because I am learning Swift 2 rather than Swift 3 I am unable to do the ++levelScore code because I get an error stating this has been removed from Swift 3.

Whats the point in continuing this course if I am certain there will be more issues like this as I go along? Should I research every time I run into this sort of issue and try to implement Swift 3 syntax? (What I will attempt to do anyway)

so ++ was completely removed from Swift 3 and I am using the newest version of Xcode and Swift 3 per an Apple Update!!

So in this case I just keep going? Hoping I don't get stuck soon....

Hi Gerardo

I don't think there will be many problems at all.

When they update Xcode it's always improving. Anything you learn for Swift 2 will be all 99% still correct in Swift 3.

There may be minor differences like what you described, as in ++levelscore longer exists. You now would just simply use levelscore += 1.

As you can see, the functionality is still there, it's just a simple syntax change.

Cheers

Simon
