Swift RestKit Post not including post data -

i'm not able data posted using following code. i've tried related posts on still can't work.

added in request descriptor, have nsdictionary mapping parameters, tried inversemapping, ect.

var parms = wearrequestparms() parms.height = height parms.width = width parms.density = density if let userid = alpinemetricshttpclient.getuserid() {      parms.userid = userid }  var objectmanager : rkobjectmanager? objectmanager = alpinemetricshttpclient.setupclient()  // var mapping = rkobjectmapping(forclass:wearrequestparms.self) var mapping = rkobjectmapping.requestmapping()  let requestmappingobjects =  ["iscircle","height","width","density","userid","wearmodel","platform"]  let dict : nsmutabledictionary = ["iscircle":"iscircle","height":"height","width":"width","density":"density","userid":"userid","wearmodel":"wearmodel","platform":"platform"]  mapping.addattributemappingsfromarray(requestmappingobjects) // mapping.addattributemappingsfromdictionary(dict [nsobject : anyobject])  // var newrequestmapping =  mapping.inversemapping()  let requestdescriptor = rkrequestdescriptor(mapping: mapping, objectclass: wearrequestparms.self, rootkeypath: "", method: rkrequestmethod.post)  objectmanager!.addrequestdescriptor(requestdescriptor)  // response let responsemapping = rkobjectmapping(forclass:poststatus.self)  var responsedescriptor = rkresponsedescriptor(     mapping: responsemapping     ,method:rkrequestmethod.post     ,pathpattern : "/api/user/registerweardevice"     ,keypath :""     ,statuscodes  :  nsindexset(index:200))  objectmanager!.addresponsedescriptor(responsedescriptor)  rkobjectmanager.sharedmanager().postobject(parms, path: "/api/user/registerweardevice", parameters: nil,     success:{ operation, mappingresult in         nslog("success")          defaults.setbool(true, forkey: "weardimensionssynced")      },     failure:{ operation, error in         nslog("error loading metric list': \(error!.localizeddescription)")         //return nil     } ); 

i shouldn't have been using rkobjectmanager.sharedmanager().postobject

this caused previous values overwritten or interfered with.

i switched

rkobjectmanager.sharedmanager().postobject 

with

objectmanager!.postobject
