NWConnection.DataTransferReport

struct · iOS 13.0+ · SDK 27.1

struct DataTransferReport

A DataTransferReport contains performance information about data transferred on an NWConnection for certain span of time. Multiple reports can be retrieved from a single connection, starting and ending at different times. This allows throughput to be measured based on how an application is using a connection. A report may be created prior to a connection moving into the .ready state, but measurements will not be collected until after the connection is ready.

aggregatePathReport

TypeScript

get aggregatePathReport(): NWConnection_DataTransferReport_PathReport

Swift declaration

let aggregatePathReport: NWConnection.DataTransferReport.PathReport

A report of path values that aggregates counters across the paths used, if there are multiple paths. If there is only one path, this will contains the values for that path. Values that can be summed are summed across paths. For values that cannot sum, the value of the primary path is used.

pathReports

TypeScript

get pathReports(): Array<NWConnection_DataTransferReport_PathReport>

Swift declaration

let pathReports: [NWConnection.DataTransferReport.PathReport]

One or more reports for paths used by the connection. Connections that are not multipath capable will only generate one path report.

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.

duration

TypeScript

get duration(): number

Swift declaration

let duration: TimeInterval

Length of time in seconds over which the report collected information. This can be used to calculate throughput for application and transport bytes counts.
