Constants that specify how a request uses network resources.


enum NetworkServiceType : UInt


The network service type provides a hint to the operating system about the nature and use of the underlying traffic. This hint enhances the system’s ability to prioritize traffic, determine how quickly it needs to wake up the cellular or Wi-Fi radio, and so on. By providing accurate information, you improve the ability of the system to optimally balance battery life, performance, and other considerations.

Most connections should be made using the NSURLRequest.NetworkServiceType.default service type.
