Is there a way get signup example select identifier.

[futomtom]

I try to find out how to get selected value , but have not a clue. Could you give me a hint how to do
In SignUpViewController.swift maleOrFemale: ViewControllerFormItem
if let x = context.returnedObject as? SwiftyFORM.OptionRowFormItem
we can get title of user selected, but is there a way to get identifier 1(male)
OptionRow("Male", "1"),
OptionRow("Female", "2"),

Thank you very much
