ios - mxSignpost 事件在 Xcode Organizer 中可见吗？

Question

我可以将一些重要的代码(我想在其中观察新应用版本的性能变化)包装在

let handle = MXMetricManager.makeLogHandle(category: "Custom Category")
mxSignpost(.begin, log: handle, name: "Custom Event Name")

和

mxSignpost(.end, log: handle, name: "Custom Event Name")

据我所知，当我使用 MXMetricManager.shared.add(someClass) 并在 MXMetricManagerSubscriber 委托(delegate)中我每 24 小时收到一次报告，这些报告将包含为 mxSignpost(.begin) 和 mxSignpost(.end) 之间的间隔单独的性能部分。

问题:

我可以在 Xcode Organizer 中看到上述代码中“自定义事件名称”或“自定义类别”的这些性能分离吗？

Metric 组织者在文档中没有此功能:

MetricKit goes beyond the metrics shown in the Metrics organizer to include average pixel luminance, cellular network conditions, and durations associated with custom OSSignpost events in your app. https://developer.apple.com/documentation/metrickit/improving_your_app_s_performance.

获取路标信息的唯一方法是检查 MXMetricPayload:

import UIKit
import MetricKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        MXMetricManager.shared.add(self)
        return true
    }

    func applicationWillTerminate(_ application: UIApplication) {
        MXMetricManager.shared.remove(self)
    }
}

extension AppDelegate: MXMetricManagerSubscriber {
    func didReceive(_ payloads: [MXMetricPayload]) {
        for payload in payloads {
            if let signpostMetrics = payload.signpostMetrics {
                for metric in signpostMetrics {
                    print(metric.description)
                }
            }
        }
    }
}
