Duration KPI (v5.5+)

The SDK provides a way to create a "duration kpi" to record the duration from time A to time B

The main use case is to record the time spent on a view

Start the timer in viewDidLoad()

Swift

override func viewDidLoad() {
    StatsManager.shared.startDurationKpi(tag: "your_screen")
}

You can optionally provide a context param, which is a [String: AnyCodable]

Swift

StatsManager.shared.startDurationKpi(tag: "your_screen", context: ["user_id": 5])

And end the timer in viewDidDisappear(_:)

Swift

override func viewDidDisappear(_ animated: Bool) {
    StatsManager.shared.endDurationKpi(tag: "your_screen")
}

You can also end all timers at the same time

Swift

StatsManager.shared.endAllDurationKpis()
