Swift - Trailing Closure Syntax

Question

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         


        

Answer 1

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)")
}
