# host The host URL subcomponent, or nil if not present. ``` var host: String? { get set } ``` ## Discussion For example, in the URL `http://www.example.com/index.html`, the host is `www.example.com`. The getter for this property removes any percent encoding this component may have (if the component allows percent encoding). Setting this property assumes the subcomponent or component string isn’t percent encoded and adds percent encoding (if the component allows percent encoding). --- Copyright © 2026 Apple Inc.
