Currently, Safari doesn’t yet emit any error messages for required values in form fields that the user has not provided (nor for invalid values the user has put into form fields). But you can enable it by using hacks or a polyfill. See HTML5 Form Validation Fallback (without a library) for a lightweight hack that enables it, and see h5Validate for a jQuery-based polyfill plugin.
