WKSecurityOrigin
An object that identifies the origin of a particular resource.
Declaration
@MainActor class WKSecurityOriginOverview
A WKSecurityOrigin object is a transient, data-only object that identifies the host name, protocol, and port number associated with a particular resource. You don’t create WKSecurityOrigin objects directly. Instead, WebKit creates them for the resources it loads. A first-party load is any load URL has the same security origin as the requesting web site. First-party webpages can access each other’s resources, such as scripts and databases.
Because a WKSecurityOrigin object is transient, it doesn’t uniquely identify a security origin across multiple delegate method calls.
