    ]
}

I have a the below model class

I have below model

**Code **

protocol arrayorDictonary { }

extension Array: arrayorDictonary { }
extension Dictionary: arrayorDictonary { }


//empty model
class EmptyModelWithData : EVObject {
    var message = ""
    var status  = ""
    var code = 0
    var data : arrayorDictonary?
}

Alamofire.request(baseURL + urlMethod , method: method ,parameters: nil, encoding: JSONEncoding.default, headers:headerDic as? HTTPHeaders).responseObject {(response : DataResponse<EmptyModelWithData>) in
            SVProgressHUD.dismiss()
            let statusCode = response.response?.statusCode
            if response.result.value != nil {
             }
  }

and i get the following warning: while doing this

WARNING: The class 'EmptyModelWithData' is not key value coding-compliant for the key 'data'
There is no support for optional type, array of optionals or enum properties.
As a workaround you can implement the function 'setValue forUndefinedKey' for this. See the unit tests for more information

Note: Data is not specific type. some time data is array. some time data is dictionary.
and sometime it would be string. so i create protocol but not working

I hope I get solution from here..

Thank you so much..

your data property should be an array of objects like this:
var data : [Pharmacy]?
And your Pharmacy object would look like:

class Pharmacy: EVObject {
   var Pid: NSNumber?
   var PharmacyName: String?
   var ContactPerson: String?
  //rest of vars
}

Since there is support for single object to array this should work if you only get 1 pharmacy as an object instead of an array

Sir my data variable is not fixed...sometime it's array..sometime it's string or sometime it's dictionary..when i work on codable decodable it's working fine..also I tried any and anyobject but not working

[maulikshah09]

If i work with codable then it's working fine.

class EmptyModelWithData: Codable {
   var message = ""
   var status = ""
   var code = 0
   var data: ParseType?
}

enum ParseType: Codable {
   case stringValue(String)
   case arrayValue([String])
   init(from decoder: Decoder) throws {
       let container = try decoder.singleValueContainer()

       if let values = try? container.decode(String.self) {
           self = .stringValue(values)
           return
       }
       if let values = try? container.decode([String].self) {
           self = .arrayValue(values)
           return
       }

       throw DecodingError.typeMismatch(ParseType.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type"))
   }

   func encode(to encoder: Encoder) throws {
       var container = encoder.singleValueContainer()
       switch self {
       case let .stringValue(x):
           try container.encode(x)
       case let .arrayValue(x):
           try container.encode(x)
       }
   }
}

Ah, then I think a property converter would be the way to go.
Below is a code snipped that you could use.
You probably have to finetune it.

class EmptyModelWithData: EVObject {
   var message: String? 
   var status: String?
   var code: NSNumber?
   var data: ParseType?

    override func propertyConverters() -> [(key: String, decodeConverter: ((Any?) -> ()), encodeConverter: (() -> Any?))] {
        return [( key: "data", decodeConverter: {
           if let d = $0 as? String {
            self.data = ParseType(d)
           } else if let d = $0 as? NSArray {
             self.data - PareType(d)
           } else if let d = $0 as? NSDictionary {
             self.data - PareType(d)
           }
        },  encodeConverter: {
            return self.data
        })]
    }
}

here the propertyConverters function will return a decodeConverter for the data element. This means that when the data element should be parsed it will use that function. It will have a parameter of type Any which comes from the raw json serialization. So indeed it could be a NSArray, NSDictionary or a simple type like String. So the code just checks the type by casting it and then creating the right enum for it.

Didn't get you... please provide me model.. so i can move ahead .. I think you can't understand my question.

One more time Explain you....

class EmptyModelWithData : EVObject {
    var message = ""
    var status  = ""
    var code = 0
    var data :  // array dictionay or string or  something else. Don't know the type 
}

I give you example for understanding..

1 ) if response is array

class EmptyModelWithData : EVObject {
var message = ""
var status = ""
var code = 0
var data : then auto add this array type
}

2. if response is string then

class EmptyModelWithData : EVObject {
var message = ""
var status = ""
var code = 0
var data : ""
}

data variable type is not fixed.if you have proper solution then provide me..I waste my 5 days to solve this issue.Please provide me proper model of EVOBject.

[evermeer]

I updated my previous command so that it shows more of the model an dI added a comment

[maulikshah09]

Don't want codable ... I want using EVOBject...I have solved with codable

[maulikshah09]

If i work with codable then it's working fine.

class EmptyModelWithData: Codable {
   var message = ""
   var status = ""
   var code = 0
   var data: ParseType?
}

enum ParseType: Codable {
   case stringValue(String)
   case arrayValue([String])
   init(from decoder: Decoder) throws {
       let container = try decoder.singleValueContainer()

       if let values = try? container.decode(String.self) {
           self = .stringValue(values)
           return
       }
       if let values = try? container.decode([String].self) {
           self = .arrayValue(values)
           return
       }

       throw DecodingError.typeMismatch(ParseType.self, DecodingError.Context(codingPath: decoder.codingPath, debugDescription: "Wrong type"))
   }

   func encode(to encoder: Encoder) throws {
       var container = encoder.singleValueContainer()
       switch self {
       case let .stringValue(x):
           try container.encode(x)
       case let .arrayValue(x):
           try container.encode(x)
       }
   }

Check this answer ... I have already Solved using Codable .. I want this using EVObject..

[maulikshah09]

Please help me To go ahead I Stuck Here... My client is reviewing my code that's why I Finding a solution otherwise I go with codable.. Data is Generic Data type...

i want like this

class EmptyModelWithData : EVObject {
var message = ""
var status = ""
var code = 0
var data : Genric datatype --> it's store dictionary ,array or something else
}

[evermeer]

What do you mean? This should work:

class EmptyModelWithData: EVObject {
   var message: String? 
   var status: String?
   var code: NSNumber?
   var data: ParseType?

    override func propertyConverters() -> [(key: String, decodeConverter: ((Any?) -> ()), encodeConverter: (() -> Any?))] {
        return [( key: "data", decodeConverter: {
           if let d = $0 as? String {
            self.data = ParseType(d)
           } else if let d = $0 as? NSArray {
             self.data - PareType(d)
           } else if let d = $0 as? NSDictionary {
             self.data - PareType(d)
           }
        },  encodeConverter: {
            return self.data
        })]
    }
}

[maulikshah09]

Yes I have solved my issue using following code:

class EmptyModelWithData : EVObject {
    var message = ""
    var status  = ""
    var code = 00
    var data: Any?
    
    override func propertyConverters() -> [(key: String, decodeConverter: ((Any?) -> ()), encodeConverter: (() -> Any?))] {
        return [( key: "data", decodeConverter: {
            if let d = $0 as? String {
                self.data = d as AnyObject
            } else if let d = $0 as? NSArray {
                self.data = d
            } else if let d = $0 as? NSDictionary {
                self.data = d
            }
        },  encodeConverter: {
            return self.data
        })]
    }
}

[evermeer]

But then if you use any, you don't have to cast. This would be good enough:

class EmptyModelWithData : EVObject {
    var message = ""
    var status  = ""
    var code = 00
    var data: Any?
    
    override func propertyConverters() -> [(key: String, decodeConverter: ((Any?) -> ()), encodeConverter: (() -> Any?))] {
        return [( key: "data", decodeConverter: {
                self.data = $0
        },  encodeConverter: {
            return self.data
        })]
    }
}

I wonder if you need a property converter at all when you use Any? Or maybe you would not need it when its of NSObject?

[maulikshah09]

I have stuck Here. don't know what is the solution I have to converted In any But when I pass this model to main view controller then I want to convert on model... Is it possible..

---

data(Any) if array then convert

to

let arrPharmacy : [PharmacyInfo]?

---

data(Any) if dictionary then

to

let arrPharmacy : PharmacyInfo?

---

class PharmacyInfo{
    var Address1 = ""
    var Address2 = ""
    var City = ""
    var ContactPerson = ""
    var EmailId = ""
    var EntryDate = ""
    var IsDelete = ""
    var ModifyDate = ""
    var PId = ""
    var PharmacyName = ""
    var honeNumer = ""
    var serId = ""
}

[maulikshah09]

Please reply on this...

[evermeer]

EVObject has an init with dictionary an Array as an init with dictionaryArray. So if you make the base class of PharmacyInfo EVObject then you could do this:
var myPI = PharmacyInfo(dictionary: theDictionary)
or
var myPIarray = [PharmacyInfo](dictionaryArray: theDictionaryArray)

Finally i got my solution...THanks...
