为什么我不能在快速操场上创建功能？

Question

I tried here http://swift-lang.org/tryswift/

func sayHello(personName: String) -> String {
    let greeting = "Hello, " + personName + "!"
    return greeting
}

error message :

Could not compile SwiftScript source: line 3:14: unexpected token: (

Answer 1

You're using the wrong Swift language – the website/online interpreter you're linking to is the site of the Swift Parallel Programming language, which has nothing to do with Apple's Swift language.

Your code works in Xcode.

Answer 2

http://swift-lang.org/tryswift/ doesn't look like it's anything to do with Apple Swift. The "try Swift" page you're using is for Swift , not Swift .

Note that Apple's has the stylised swift in its logo heading downwards; the parallel scripting language Swift is heading upwards :)

To try Apple's Swift in a similar way, you'll need the Xcode 6 beta and a "playground" file.

Answer 3

That is a whole different Swift language which has been existing for a while.

The playground for Apple's Swift is available as a Desktop application only at the moment. Follow the links from here - https://developer.apple.com/swift/
