Class

MXMetricManager

The object that registers you to receive metrics, creates logs for custom metrics, and gives access to past reports.

Declaration

class MXMetricManager : NSObject

Overview

The MXMetricManager shared object manages your subscription for receiving on-device daily metrics.

To receive metrics, call add(_:) with an object supporting the didReceive(_:) method of MXMetricManagerSubscriber. The system then sends a report as an array of MXMetricPayload objects at most once per day. The array contains the metrics from the past 24 hours and any previously undelivered daily reports.

class AppDelegate: UIResponder, UIApplicationDelegate, MXMetricManagerSubscriber {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    
        let shared = MXMetricManager.shared
        shared.add(self)
        
        return true
    }

    // Receive daily metrics
    func didReceive(_ payloads: [MXMetricPayload]) {
       // Process metrics
    }
...
}
