swift - How do i create an optional var with no value inline -


i have method returns optional integer one:

func foo(bar:string) -> int? {     if(bar == "bar")     {         return 42     }     else     {         var nothing:int?         return nothing     } }

i'd return no value without creating var, possible?

return nothing:int?

would expect...

thanks in advance.

use

return nil

you not need specify type - have provided in function return type already.
