Declaration

struct NWPath

Topics

Checking Path Availability

let status: NWPath.Status

A status indicating whether a path can be used by connections.

enum NWPath.Status

Status values indicating whether a path can be used by connections.

Inspecting Interfaces

func usesInterfaceType(NWInterface.InterfaceType) -> Bool

Checks if connections using the path may send traffic over a specific interface type.

let availableInterfaces: [NWInterface]

A list of all interfaces available to the path, in order of preference.

var gateways: [NWEndpoint]

A list of gateways configured on the interfaces available to a path.

Checking Path Capabilities

let supportsIPv4: Bool

A Boolean indicating whether the path can route IPv4 traffic.

let supportsIPv6: Bool

A Boolean indicating whether the path can route IPv6 traffic.

let supportsDNS: Bool

A Boolean indicating whether the path has a DNS server configured.

var isConstrained: Bool

A Boolean indicating whether the path uses an interface in Low Data Mode.

let isExpensive: Bool

A Boolean indicating whether the path uses an interface that is considered expensive, such as Cellular or a Personal Hotspot.

var debugDescription: String

The description of the network path.

Inspecting Connected Paths

let localEndpoint: NWEndpoint?

The local endpoint in use by a connection's network path.

let remoteEndpoint: NWEndpoint?

The remote endpoint in use by a connection's network path.

Comparing Paths

static func != (NWPath, NWPath) -> Bool

Returns a Boolean value indicating whether two values are not equal.
