Chapter 8 shortened closures

[pawi552]

var multiplyClosure = { (a, b) in
    a*b
}

Is causing error “Ambiguous use of operator ‘*’”

Same error for

var multiplyClousure = {

    $0 * $1

}

@pawi552 Thanks very much for your question!

Most likely you’re getting the error because you have not identified what type “a” and “b” are. There is nothing to indicate that they can be multiplied.
