VeraCode Scan- Found a Valid Username and Password [Swift]

I have Uploaded the .bca extension build to Veracode Scanner. My application Uses Touch ID for User to Login to the Application.

      func viewWillAppear(_animated: Bool)
      {
        super.viewWillAppear(animated)
       let context : LAContext()
       let authError : NSError?
       guard context.canEvalutePolicy(.deviceOwnerAuthenticationWithBiometrics,error: &authError) else{return}
       navigateToHomeController() 

     }
    func navigateToHomeController()
    {
      let context : LAContext()
      let authError : NSError?
      context.evaluatePolicy(LAPolicy.deviceOwnerAuthentication, localizedReason: reasonString, reply: { [unowned self] (success: Bool, evalPolicyError: Error?) in 
          if success
          {
            //*Do Something*
            }
         }

Every Time i Upload a Build to Veracode it is Showing Severity Finding High With CWE 287 (Flaw ID’s: 2,12) and Asking a Strong password policy. How to have Policy for Fingerprint??

    LAPolicy()

Has Only two Policies as

    .deviceOwnerAuthentication
     .deviceOwnerAuthenticationWithBiometrics

context.evaluatePolicy()
context.canEvaluatePolicy()

Can Anyone Help me out Somehow?
