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 ?
