NWConnection.EstablishmentReport

struct · iOS 13.0+ · SDK 27.1

struct EstablishmentReport

An EstablishmentReport contains information about how an NWConnection became established. This is intended to be used for analysis of performance after connection establishment. The report cannot be gathered until a connection is in the .ready state.

handshakes

TypeScript

get handshakes(): Array<NWConnection_EstablishmentReport_Handshake>

Swift declaration

let handshakes: [NWConnection.EstablishmentReport.Handshake]

An array of zero or more Handshake reports, in order from first completed (thus, lowest level in the stack) to last completed.

get · iOS 13.0+

resolutions

TypeScript

get resolutions(): Array<NWConnection_EstablishmentReport_Resolution>

Swift declaration

let resolutions: [NWConnection.EstablishmentReport.Resolution]

An array of zero or more Resolution reports, in order from first resolved to last resolved.

proxyEndpoint

TypeScript

get proxyEndpoint(): (NWEndpoint) | null

Swift declaration

let proxyEndpoint: NWEndpoint?

The endpoint of the proxy used by a connection, if applicable.

get · iOS 13.0+

proxyConfigured

TypeScript

get proxyConfigured(): boolean

Swift declaration

let proxyConfigured: Bool

A boolean indicating if a proxy configuration applied to the connection, even if the connection did not ultimately use a proxy.

debugDescription

TypeScript

get debugDescription(): string

Swift declaration

var debugDescription: String { get }

A textual representation of this instance, suitable for debugging. Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the `String(reflecting:)` initializer. This initializer works with any type, and uses the custom `debugDescription` property for types that conform to `CustomDebugStringConvertible`: struct Point: CustomDebugStringConvertible { let x: Int, y: Int var debugDescription: String { return "(\(x), \(y))" } } let p = Point(x: 21, y: 30) let s = String(reflecting: p) print(s) // Prints "(21, 30)" The conversion of `p` to a string in the assignment to `s` uses the `Point` type's `debugDescription` property.

previousAttemptCount

TypeScript

get previousAttemptCount(): number

Swift declaration

let previousAttemptCount: Int

The number of connection attempts made before the successful attempt.

get · iOS 13.0+

attemptStartedAfterInterval

TypeScript

get attemptStartedAfterInterval(): number

Swift declaration

let attemptStartedAfterInterval: TimeInterval

The delay after calling start() before the successful connection attempt began. For connections that succeed on the first attempt, this value will be 0. For connections that move into the .waiting state, this value will be greater than 0.

get · iOS 13.0+

duration

TypeScript

get duration(): number

Swift declaration

let duration: TimeInterval

The duration of the connection's establishment in seconds. This is the total time from when the successful connection attempt began until the connection becomes ready, including resolution, proxy evaluation, and protocol handshakes.

usedProxy

TypeScript

get usedProxy(): boolean

Swift declaration

let usedProxy: Bool

A boolean indicating if the connection was established through a proxy.
