Instance Property


A copy of the configuration object for this session.


@NSCopying var configuration: URLSessionConfiguration { get }


Beginning in iOS 9 and OS X 10.11, URLSession objects store a copy of the URLSessionConfiguration object passed to their initializers, such that a session’s configuration is immutable after initialization. Any further changes to mutable properties on the configuration object passed to a session’s initializer or the value returned from a session’s configuration property do not affect the behavior of that session. However, you can create a new session with the modified configuration object.
