iOS14で強化されたMetricKitで不具合対応に備える

Last updated at Posted at 2021-06-29

MetricKitとは

  • MXMetricPayload
    • iOS13以降対応
    • アプリの基本情報、診断、パフォーマンスを取得可能
    • 過去24時間のデータを含むレポートを最大で1日1回受信
  • MXDiagnosticPayload 
    • iOS14以降対応
    • クラッシュやユーザがアプリを利用する上での障害情報

利用用途

  • 利用者の端末情報蓄積
  • 不具合対応の情報取得

取得できるデータについて

MXMetricPayload

  • パフォーマンス
    • CPU情報
    • ディスプレイ情報
    • GPU情報
    • 位置情報
    • ネットワーク情報
  • 応答性
    • アプリの起動と再開
    • アニメーションの応答性
    • ユーザインタラクションに対する応答性
  • ストレージ
    • ディスク情報

MXDiagnosticPayload

  • クラッシュ
    • クラッシュレポート
    • CPU例外レポート
    • アプリビジーレポート
    • ディスク書き込み例外レポート

導入方法について

AppDelegate.swift
/// 1. 使用の為にimport
import MetricKit
~  ~
extension AppDelegate: UIApplicationDelegate {
~  ~
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
        if #available(iOS 13.0, *) {
            /// 2.起動時に登録
            MXMetricManager.shared.add(self)
        }
~  ~
    }

    func applicationWillTerminate(_ application: UIApplication) {
        if #available(iOS 13.0, *) {
            /// 3.終了時に解除
            MXMetricManager.shared.remove(self)
        }
    }
}

extension AppDelegate: MXMetricManagerSubscriber {
    /// 4.情報を取得する(MXMetricPayload)
    @available(iOS 13.0, *)
    func didReceive(_ payloads: [MXMetricPayload]) {
        for payload in payloads {
            let json = payload.jsonRepresentation()
            let jsonString = String(data: json, encoding: .utf8) ?? .empty
            Log.info("[MXMetricPayload] \(jsonString)")
        }
    }

    /// 5.情報を取得する(MXDiagnosticPayload)
    @available(iOS 14.0, *)
    func didReceive(_ payloads: [MXDiagnosticPayload]) {
        for payload in payloads {
            let json = payload.jsonRepresentation()
            let jsonString = String(data: json, encoding: .utf8) ?? .empty
            Log.info("[MXDiagnosticPayload] \(jsonString)")
        }
    }
}
