IOS code access, no error code (always undefined)

[Robernator]

On an IOS device when canceling the access code, you do not receive an error code. With Android you get an error code 60 with IOS, the error is always undefined. I cannot make a distinguish whether or not the access code is enabled on the device.

It's possible on iOS the user can end up locking access to the security within the app.

I use the following code to check

 if (isIOS) {
              // check if Biometry is locked out.
              const laContext = LAContext.new();
              laContext.evaluatePolicyLocalizedReasonReply(
                LAPolicy.DeviceOwnerAuthentication,
                'test',
                (ok: boolean, error: NSError) => {
                  if (!ok) {
                    console.log(error.code, error.localizedDescription);
                    if (error.code === LAError.BiometryLockout) {
                     console.log(
                        `Biometry is locked out. User must enter passcode to enable Biometry.`,
                      );
                    } else if (error.code === LAError.UserCancel) {
                      console.log(`The user tapped the cancel button in the authentication dialog.`);
                      reject();
                    }
                    resolve();
                  } else {
                    resolve(ok);
                  }
                },
              );
            } 

I end up checking that if the available call does NOT return result.any in the promise.
