SwiftUI를 사용하는 경우 앱 대리자를 만들고 UIApplicationDelegateAdaptor 또는 NSApplicationDelegateAdaptor를 통해 App 구조체에 연결해야 합니다. 앱 대리자 재구성도 중지해야 합니다. 자세한 내용은 SwiftUI 안내를 참조하세요.

(선택사항) Apple 광고 네트워크 기여 분석 등록 사용 중지
개발자 편의를 위해 SDK는 SKAdNetwork를 통한 광고 네트워크 기여 분석을 위해 앱을 Apple에 자동으로 등록합니다.
이 기능을 사용 중지하려면 앱의 info.plist 파일에서 GOOGLE_ANALYTICS_REGISTRATION_WITH_AD_NETWORK_ENABLED를 NO(불리언)로 설정합니다.
이벤트 로깅 시작
FirebaseApp 인스턴스를 구성한 후에는 logEvent() 메서드를 사용하여 이벤트 로깅을 시작할 수 있습니다.
모든 앱에 권장되는 특정 이벤트가 있으며 특정 비즈니스 유형이나 카테고리에 권장되는 이벤트가 있습니다. 추천 이벤트를 사전 정의된 파라미터와 함께 전송해야 합니다. 이렇게 하면 보고서에 세부정보가 최대한 포함되고 향후 기능 및 통합을 즉시 사용할 수 있습니다. 이 섹션에서는 사전 정의된 이벤트 로깅을 보여줍니다. 이벤트 로깅에 대한 자세한 내용은 이벤트 로깅을 참조하세요.
다음 예시에서는 사용자가 앱의 특정 요소를 클릭했음을 나타내는 추천 이벤트를 로깅하는 방법을 보여줍니다.

(Banners display in the Analytics dashboard if an upgrade is required.) The associated Terms of Service must be [accepted by February 15, 2022](https://support.google.com/analytics/answer/10960488) to ensure data collection continues. See the Support FAQ on the upgrade for help [finding project Owners](/support/faq#analytics-upgrade-tos).\n\nWhen you enable Google Analytics in your project, your Firebase web apps\nare linked to Google Analytics data streams associated with an\n[App + Web property](//developers.google.com/analytics/devguides/collection/app-web/tag-guide).\n\nAdd the Analytics SDK to your app\n---------------------------------\n\nDepending on how your web application is hosted, your configuration may be\nhandled automatically or you may need to update your\n[Firebase configuration object](/docs/projects/learn-more#config-files-objects).\nIf your web app already uses Google Analytics, you may need to do additional\nsetup described in [Use Firebase with existing gtag.js tagging](#firebase-gtag).\n\n1. Check that your Firebase config object in your code contains\n `measurementId`. This ID is automatically created when you enable\n Analytics in your Firebase project and register a web app, and it's\n required to use Analytics.\n\n | **Note:** For apps using the **Firebase JavaScript SDK v7.20.0 and later** , Firebase dynamically fetches the `measurementId` when your app initializes Analytics. Having this ID in your config object is optional, but it does serve as a fallback in the rare case that the dynamic fetch fails.\n - **If your app uses Firebase Hosting *and* uses\n [reserved URLs](/docs/hosting/reserved-urls) for the Firebase SDKs**:\n\n Firebase automatically handles configuring your application. To complete\n setup, add the scripts from the ***Your apps*** card in your\n [Project settings](https://console.firebase.google.com/project/_/settings/general/)\n to the \\\u003cbody\\\u003e tag of your app, if you haven't already.\n - **If your app does not use reserved URLs** :\n **If you're working with an existing web app** , update the Firebase config\n object in your code to ensure the `measurementId` field is present. The\n config object should look similar to the following example:\n\n // For Firebase JavaScript SDK v7.20.0 and later, `measurementId` is an optional field\n const firebaseConfig = {\n apiKey: \"\u003cvar translate=\"no\"\u003eAPI_KEY\u003c/var\u003e\",\n authDomain: \"\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e.firebaseapp.com\",\n databaseURL: \"https://\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e.firebaseio.com\",\n projectId: \"\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e\",\n storageBucket: \"\u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e`.firebasestorage.app`\",\n messagingSenderId: \"\u003cvar translate=\"no\"\u003eSENDER_ID\u003c/var\u003e\",\n appId: \"\u003cvar translate=\"no\"\u003eAPP_ID\u003c/var\u003e\",\n measurementId: \"G-\u003cvar translate=\"no\"\u003eGA_MEASUREMENT_ID\u003c/var\u003e\"\n };\n\n2. If you haven't already, [install the Firebase JS SDK and initialize Firebase](/docs/web/setup#add-sdk-and-initialize).\n\n3.

You should send\nsuggested events along with their prescribed parameters, to ensure maximum\navailable detail in your reports and to benefit from future features and\nintegrations as they become available. This section demonstrates logging a\npre-defined event, for more information on logging events, see\n[Log events](/docs/analytics/events?platform=web).\n\nThe following example demonstrates how to log a recommended event to indicate a\nuser has received a notification in your app: \n\n### Web\n\n```javascript\nimport { getAnalytics, logEvent } from \"firebase/analytics\";\n\nconst analytics = getAnalytics();\nlogEvent(analytics, 'notification_received');https://github.com/firebase/snippets-web/blob/467eaa165dcbd9b3ab15711e76fa52237ba37f8b/snippets/analytics-next/index/analytics_log_event.js#L8-L11\n```\n\n### Web\n\n```javascript\nfirebase.analytics().logEvent('notification_received');https://github.com/firebase/snippets-web/blob/467eaa165dcbd9b3ab15711e76fa52237ba37f8b/analytics/index.js#L12-L12\n```\n\nNext steps\n----------\n\n- Understand [each Analytics report](/docs/analytics/reports).\n- Use the [DebugView](/docs/analytics/debugview) to verify your events.\n- Explore your data in the [Firebase console](//console.firebase.google.com/project/_/analytics/).\n- Explore the guides on [events](/docs/analytics/events?platform=web) and [user properties.](/docs/analytics/user-properties?platform=web)\n- Learn how to export your data to [BigQuery.](https://support.google.com/firebase/answer/7030014)"]]
