Swift错误中的“ For”循环？

Question

Here is my 'for' loop:

let size:Int = 64
for var z = 0;z < size;++z{    
}

I think the syntax is right, but the compiler always tells me:

is it bug or something?

ps: Xcode version6.1.1

Answer 1

From your screenshot, it looks like you're inserting code in the body of a class directly. You should move it to, eg, the body of a method. Then it will compile fine.

I would still encourage you to insert spaces after ; and : for readability, however.
