How to write a generic apply() function in Swift?

Question

Is there any way to get the following working in Swift 3?

 let button = UIButton().apply {
        $0.setImage(UIImage(named: \"UserLocation\"), for: .normal         


        

Answer 1

I had the same issue and ended up solving it with an operator:

infix operator <-< : AssignmentPrecedence
func <-<(left:T, right:(T)->()) -> T
{
  right(left)
  return left
}

let myObject = UIButton() <-< { $0.isHidden = false }
