How to println by swift in terminal?

Question

I'm trying to run ./swift -emit-executable shape.swift by terminal

shape.swift

class Shape
{
    let name:String = ""

    init(name:String)
    {
        self.name = name
    }

    let anyShape = Shape.init(name:"Jaum")
    println("Name, \(anyShape.name).")
}

I'm getting this error:

shape.swift:11:5: error: expected declaration
    println("Name, \(anyShape.name).")
    ^

What am I doing wrong?

You can't have declarations at the root level of a class, move them outside.

Don't use .init to create a class instance.

Use print instead of println (it has changed in Swift 2).

And don't give a value of "" to your immutablename if you want to use the initializer, just declare the type.

class Shape {

    let name:String

    init(name:String) {
        self.name = name
    }

}

let anyShape = Shape(name:"Jaum")

print("Name, \(anyShape.name).")

Last note, it's not swift but swiftc which is able to create an executable:

swiftc -emit-executable shape.swift
