Getting value nill after mapping

[krishnasolankiBigbang]

class of mapping is ::
class XYZSetting: NSManagedObject {

var address_id:NSNumber!
var client_name:String!
var clientvendorid:NSNumber!
var company_id:NSNumber!
var location_type:NSNumber!
var modified_by:NSNumber!
var user_id:NSNumber!
var userlocationtype:NSNumber!
var clientaddress:AddressList?


class func entityName()->String{
    return "XYZSetting"
}

class func defaultMapping()->FEMMapping{
    let mapping = FEMMapping.init(entityName: self.entityName())
    mapping.addAttribute(Mapping.intAttributeFor(property: "user_id", keyPath: "UserID"))
    //mapping.addAttribute(Mapping.intAttributeFor(property: <#T##String#>, keyPath: <#T##String#>))
    mapping.addAttribute(Mapping.intAttributeFor(property: "company_id", keyPath: "CompanyID"))
    mapping.addAttribute(Mapping.intAttributeFor(property: "address_id", keyPath: "AddressID"))
    mapping.addAttribute(Mapping.intAttributeFor(property: "clientvendorid", keyPath: "ClientVendorID"))
     mapping.addAttribute(Mapping.intAttributeFor(property: "location_type", keyPath: "LocationType"))
    mapping.addAttribute(Mapping.intAttributeFor(property: "modified_by", keyPath: "ModifiedBy"))
    mapping.addAttribute(Mapping.intAttributeFor(property: "user_location_type", keyPath: "UserLocationType"))
    mapping.addAttributes(from: ["client_name":"ClientName"])
mapping.addRelationshipMapping(AddressList.defaultmapping(), forProperty: "clientaddress", keyPath: "ClientAddress")
    mapping.primaryKey = "clientvendorid"
    return mapping
}
class func getAll()->[DefaultSetting]{
    return XYZSetting.mr_findAll() as? [XYZSetting] ?? [XYZSetting]()
}
class func getDefaultSetting()->XYZSetting?{

    if let dsetting = XYZSetting.mr_findFirst(in: NSManagedObjectContext.mr_default()) as? XYZSetting{ 
       {
        if let defaultsetting = XYZSetting.mr_findAll()?.first as? DefaultSetting{
            print("address id = \(defaultsetting.address_id)")
            //print(defaultsetting.userid)
            print("Location  type = \(defaultsetting.location_type)")
            }
        print("location type in model  = \(dsetting.location_type)")
       return dsetting
    }

else{
return nil
}
}
}

code for mapping is ::

MagicalRecord.save({ (localcontext) in
XYZSetting.mr_truncateAll(in: localcontext)
print("count of default setting is = (XYZSetting.getAll().count)")
let arr = FEMDeserializer.collection(fromRepresentation: [dic], mapping: XYZSetting.defaultMapping(), context: localcontext)
print("setting arr = (arr)")
print("count of default setting after mapping (XYZSetting.getAll().count)")

localcontext.mr_save({ (localcontext) in
print("saving")
}, completion: { (status, error) in
print("status = (status)")
print("saved")
print("get default setting (XYZSetting.getDefaultSetting())")
print("Location type using default = (XYZSetting.getDefaultSetting()?.location_type)")
if let defaultsetting = XYZSetting.mr_findAll()?.first as? DefaultSetting{
print("address id = (defaultsetting.address_id)")
//print(defaultsetting.userid)
print("Location type = (defaultsetting.location_type)")
}
})

Getting log is this ::
"
