automatic ref counting - Swift weak self function retention -

-

if have closure references weak var weakself = self, can change closure direct function reference, through weakself?

struct closureholder {     let closure: () -> void }  class closuresource {     func hello() {         nslog("hello")     }      func createweakselfwithininnerclosureclosureholder() -> closureholder {         weak var weakself = self         return closureholder(closure: {             weakself?.hello()         })     }      func createweakselfdothelloclosureholder() -> closureholder {         weak var weakself = self         // code below won't compile because weakself optional.         // once unwrap optional, no longer have weak reference.         // return closureholder(closure: weakself.hello)          // strongifies weak reference. :(         return closureholder(closure: weakself!.hello)     } }

instead of createweakselfwithininnerclosureclosureholder, i'd prefer createweakselfdothelloclosureholder.

no can't. saying self.foo (if foo method) same thing saying myclass.foo(self). , methods curried in fashion keep strong reference receiver object. if want maintain weak reference, need stick { weakself?.hello() } approach.
