ios - Invalid top-level type in JSON write in Swift -
i'm trying put using afnetworking. need send array of participants in competition, i'm getting "invalid top-level type in json write in swift" error. json generate perfect, , if try using rest client works. here's code:
func sendusers(oncomplete: (nserror?) -> void) { var error: nserror? var jsondata: nsdata = nsjsonserialization.datawithjsonobject(self.createdictionaryofparticipations(), options: nsjsonwritingoptions.allzeros, error: &error)! var jsonstring: string = nsstring(data: jsondata, encoding: nsutf8stringencoding)! println("json: \(jsonstring)") if self.requestmanager == nil { self.requestmanager = afhttprequestoperationmanager(); } self.requestmanager?.responseserializer = afjsonresponseserializer(); let requestserializer = afjsonrequestserializer() self.requestmanager?.requestserializer = requestserializer; self.requestmanager?.requestserializer.setvalue("application/json", forhttpheaderfield: "content-type"); self.requestmanager?.put(kparticipantsurl, parameters: jsonstring, success: { (operation: afhttprequestoperation!, object: anyobject!) -> void in self.persistusers([]) oncomplete(nil) }, failure: { (operation: afhttprequestoperation!, error: nserror!) -> void in oncomplete(error) }) } and method within create jsonobject:
func createdictionaryofparticipations() -> nsarray { var dict: nsmutabledictionary = nsmutabledictionary() var participants: nsmutablearray = nsmutablearray() var savedparticipants: [user] = self.getusers() [user] participant: user in savedparticipants { var participantdict: nsmutabledictionary = nsmutabledictionary() participantdict.setvalue(participant.name, forkey: knamekey) participantdict.setvalue(participant.firstsurname, forkey: kfirstsurnamekey) participantdict.setvalue(participant.secondsurname, forkey: ksecondsurnamekey) participantdict.setvalue(participant.dni, forkey: kdnikey) participantdict.setvalue(participant.address, forkey: kaddresskey) participantdict.setvalue(participant.postalcode, forkey: kpostalcodekey) participantdict.setvalue(participant.city, forkey: kcitykey) participantdict.setvalue(participant.province, forkey: kprovincekey) participantdict.setvalue(participant.phone, forkey: kphonekey) participantdict.setvalue(participant.email, forkey: kemailkey) participantdict.setvalue(participant.code, forkey: kcodekey) participantdict.setvalue(participant.prize, forkey: kprizekey) participants.addobject(participantdict) } return participants } if run app , send request, error:

you're doing json serialisation yourself, , asking afn again, you're passing nsstring , asking serialised json, won't work.
what should doing passing nsarray returned createdictionaryofparticipations instead:
self.requestmanager?.put(kparticipantsurl, parameters: self.createdictionaryofparticipations(), success:...
