ios - Realm model contains property but not found it at runtime

Question

I am getting error as below

Invalid property name , reason: 'Property 'IsRecordDeleted' not found in object of type 'MyCustomModel'

Where as my Model is as Under

@objcMembers public class MyCustomModel : Object {
dynamic var   Id : String = ""
dynamic var   ProductId : String? = ""
dynamic var   IsRecordDeleted : Bool? = false
dynamic var   ProductBarcode : String? = ""


override public class func primaryKey() -> String? {
    return "Id"
}

}

and I am making query like this :

let mSavedItems = mDbHelper.realmObj.objects(MyCustomModel.self).filter("IsRecordDeleted = false")

What could be problem here. I do not know why my app is crashing with the same error. But If I change the value like

    let mSavedItems = mDbHelper.realmObj.objects(MyCustomModel.self).filter("ProductId = 0")

The app gets run, but crashed on when I use IsRecordDeleted in predicate.

Please tell me what could be problem

You can try

let mSavedItems = mDbHelper.realmObj.objects(MyCustomModel.self)
let filtered = mSavedItems.filter { $0.IsRecordDeleted == false }

and

let mSavedItems = mDbHelper.realmObj.objects(MyCustomModel.self) 
let filtered = mSavedItems.filter { $0.ProductId == "0" }

For both

let mSavedItems = mDbHelper.realmObj.objects(MyCustomModel.self) 
let filtered = mSavedItems.filter {
   $0.IsRecordDeleted == false 
   && $0.ProductId == "0" 
}

//

let resultPredicate = NSPredicate(format: "ProductId == '0' AND IsRecordDeleted == false")
let filtered = mSavedItems.filter(resultPredicate)
