about capture list in nested function


#1

Hello

For me more good use nested function instead of closure. How in this case right way to define capture list?

//With Closure

class Sender {

 var color =  "Orange"

 var writer =  Receiver \(\)

 func something\(\) \{
     writer \. callback = \{ \[weak  self \] newColor  in
         guard let strongSelf =  self else \{  return \}
        strongSelf\. color = newColor
    \}
\}

}

class Receiver {
var callback: (( String ) -> Void )?

 func somework\(\) \{
     var color =  "green"
     guard let cb =  callback else \{  return \}
    cb\(color\)
\}

}

//Alternatively with Nested Function

class ASender {

 var color =  "Orange"

 var writer =  Receiver \(\)

 func something\(\) \{
     writer \. callback =  change
\}

 func change\(name:  String \) \{
     weak var n =  self // is right or not?
     guard let strongSelf = n  else \{  return \}
    strongSelf\. color = name
\}

}
