Getting crash App While Mapping

[krishnasolankiBigbang]

Hello
I am using swift verison pod 'FastEasyMapping', '~> 1.2'.

I am getting error :: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<__NSCFString 0x6000001d97e0> valueForUndefinedKey:]: this class is not key value coding-compliant for the key ID
Getting exception in line FEMDeserializer.collection(fromRepresentation: arrPlanVisit, mapping: ABC.defaultmapping(), context: localContext)

class of ABC is ::
import UIKit

@objc(ABC)
class ABC: NSManagedObject {
//
@NSManaged var ID: Int64

class func defaultmapping()->FEMMapping{
let mapping = FEMMapping.init(entityName: "ABC")
mapping.addAttribute(Mapping.intAttributeFor(property: "iD", keyPath: "ID"))
return mapping
}

Response from Server ::

• key : "ABC"
  ▿ value : 10 element
  ▿ 8 : 2 elements
  - key : ID
  - value : 1641
  @dimazen any solution for this ?
