I\'m introducing a Result framework (antitypical) in some points of my app. In example, given this function:

func find         


        

Answer 1

Try this

Note this is example you can change as per your test

typealias resultHandler = (_ responseItems: AnyObject, _ error: Error) -> Void

func deleteItem(byId: Int, completion: resultHandler){
       completion(Items, error) 
 }

Calling

self.deleteItem(byId: 1) { (result, error) in
            if error ==nil{

            }
        }
