Swift - Trailing Closure Syntax

I'm diving into Swift lang by Apple and have some problems using the trailing closure syntax, example:

func test(txt: String, resolve: (name: String) -> Void) {
   resolve(name: "Dodo")
}

// Errors here complaining on resolve param
test("hello", (name: String) {
   println("callback")
})

How to fix it?

you have the wrong closure syntax

test("hello", {(name: String) in 
    println("callback")
})

or

test("hello", {
   println("callback: \($0)")
})

or

test("hello") {(name: String) in 
    println("callback")
}

or

test("hello") {
   println("callback: \($0)")
}
