objective c - Syntax for passing “no options” to a parameter of type NSJSONWritingOptions -

-

in objective-c wrote code following:

nserror *error; nsdata *jsondata = [nsjsonserialization datawithjsonobject:somedictionary                                                    options:0                                                      error:&error];

i trying same thing in swift. prompting xcode’s syntax checking wrote this:

var jsonerror: nserror let jsondata = nsjsonserialization.datawithjsonobject(somedictionary, options: nsjsonwritingoptions(), error: &jsonerror)

but gives me error: “could not find overload init accepts supplied arguments.” think problem might nsjsonwritingoptions() bit, , i’m guessing have swift syntax wrong. tried replacing nsjsonwritingoptions() nsjsonwritingoptions(0) , got same error; tried replacing nil (as suggested this answer) got error “could not find overload __conversion accepts supplied arguments.”

how can indicate want default json writing options, whatever might be?

the problem not nsjsonwritingoptions; type of error you're passing should nserror?, not nserror.
