Instance Property

delegate

The delegate assigned when this object was created.

Declaration

var delegate: URLSessionDelegate? { get }

Discussion

This delegate object is responsible for handling authentication challenges, for making caching decisions, and for handling other session-related events. The session object keeps a strong reference to this delegate until your app exits or explicitly invalidates the session. If you do not invalidate the session, your app leaks memory until it exits.
