Initializer

init(configuration:delegate:delegateQueue:)

Creates a session with the specified session configuration, delegate, and operation queue.

Declaration

init(configuration: URLSessionConfiguration, delegate: URLSessionDelegate?, delegateQueue queue: OperationQueue?)

Parameters

configuration

A configuration object that specifies certain behaviors, such as caching policies, timeouts, proxies, pipelining, TLS versions to support, cookie policies, and credential storage.

See URLSessionConfiguration for more information.

delegate

A session delegate object that handles requests for authentication and other session-related events.

This delegate object is responsible for handling authentication challenges, for making caching decisions, and for handling other session-related events. If nil, the class should be used only with methods that take completion handlers.

queue

An operation queue for scheduling the delegate calls and completion handlers. The queue should be a serial queue, in order to ensure the correct ordering of callbacks. If nil, the session creates a serial operation queue for performing all delegate method calls and completion handler calls.
