Utilizza Swift Package Manager per installare e gestire le dipendenze di Firebase.
In Xcode, con il progetto dell'app aperto, vai a File > Add Packages (File > Aggiungi pacchetti).
Quando richiesto, aggiungi il repository dell'SDK delle piattaforme Apple di Firebase:
https://github.com/firebase/firebase-ios-sdk.git
Scegli la raccolta Performance Monitoring.
Aggiungi il flag -ObjC alla sezione Altri flag del linker delle impostazioni di build del target.
Al termine, Xcode inizierà automaticamente a risolvere e a scaricare le tue dipendenze in background.
A questo punto, configura il modulo Firebase:
Importa il modulo FirebaseCore nel tuo
UIApplicationDelegate, nonché tutti gli altri
moduli Firebase utilizzati dal delegato dell'app.
Ad esempio, per utilizzare Cloud Firestore e Authentication:
// Use Firebase library to configure APIsFirebaseApp.configure()
Swift
// Use Firebase library to configure APIsFirebaseApp.configure()
Objective-C
// Use Firebase library to configure APIs[FIRAppconfigure];
Se utilizzi SwiftUI, devi creare un delegato dell'applicazione e collegarlo
alla struttura App tramite UIApplicationDelegateAdaptor o
NSApplicationDelegateAdaptor. Devi anche disattivare lo swizzling del delegato dell'app. Per
ulteriori informazioni, consulta le istruzioni per SwiftUI.
SwiftUI
@mainstructYourApp:App{// register app delegate for Firebase setup@UIApplicationDelegateAdaptor(AppDelegate.self)vardelegatevarbody:someScene{WindowGroup{NavigationView{ContentView()}}}}
Ricompila l'app.
Passaggio 2: genera eventi di rendimento per la visualizzazione iniziale dei dati
Firebase inizia a elaborare gli eventi quando aggiungi correttamente l'SDK alla tua app. Se stai ancora sviluppando localmente, interagisci con la tua app per generare eventi per la raccolta e l'elaborazione iniziali dei dati.
Continua a sviluppare la tua app utilizzando un simulatore o un dispositivo di test.
Genera eventi passando più volte dall'app in background a quella in primo piano, interagendo con l'app spostandoti tra le schermate e/o attivando richieste di rete.
Vai alla dashboard sul rendimento
della console Firebase. Dovresti visualizzare i dati iniziali entro
pochi minuti.
Fai clic sull'URL per visualizzare i dati nella console Firebase. Potrebbero essere necessari alcuni
istanti prima che i dati vengano aggiornati nella dashboard.
Passaggio 4: (facoltativo) aggiungi il monitoraggio personalizzato per un codice specifico
Per monitorare i dati sul rendimento associati a un codice specifico nella tua app, puoi
strumentare le tracce di codice personalizzato.
Con una traccia di codice personalizzata, puoi misurare il tempo impiegato dalla tua app per completare
un'attività o un insieme di attività specifico, ad esempio il caricamento di un insieme di immagini o l'interrogazione
del database. La metrica predefinita per una traccia di codice personalizzato è la durata, ma
puoi anche aggiungere metriche personalizzate, come hit della cache e avvisi di memoria.
Nel codice, definisci l'inizio e la fine di una traccia di codice personalizzato (e aggiungi le metriche personalizzate che preferisci) utilizzando l'API fornita dall'SDK Performance Monitoring.
Passaggio 5: esegui il deployment dell'app e rivedi i risultati
Dopo aver convalidato Performance Monitoring utilizzando il simulatore Xcode e uno o più
dispositivi di test, puoi eseguire il deployment della versione aggiornata dell'app per gli utenti.
Puoi monitorare i dati sul rendimento nella
dashboard Rendimento
della console Firebase.
Problemi noti
Performance Monitoring presenta problemi noti di compatibilità con GTMSQLite. Ti consigliamo di non
utilizzare Performance Monitoring con le app che utilizzano GTMSQLite.
Lo swizzling dei metodi dopo la chiamata a FirebaseApp.configure() potrebbe interferire con
l'SDK Performance Monitoring.
I problemi noti relativi al simulatore iOS 8.0-8.2 impediscono a Performance Monitoring di
acquisire gli eventi di rendimento. Questi problemi sono stati risolti nel simulatore iOS 8.3
e nelle versioni successive.
Le connessioni stabilite utilizzando backgroundSessionConfiguration di NSURLSession
mostreranno tempi di connessione più lunghi del previsto. Queste connessioni vengono
eseguite out-of-process e le tempistiche riflettono gli eventi di callback in-process.

If you choose to install Firebase using [Swift Package Manager](/docs/ios/swift-package-manager), you can skip CocoaPods-related steps, like modifying Podfiles and running the `pod` command.\n\n**Step 1** : Add Performance Monitoring to your app\n\nAfter you've added the Performance Monitoring SDK, Firebase automatically starts collecting\ndata for your app's [screen rendering](/docs/perf-mon/screen-traces), data\nrelated to your app's lifecycle (like\n[app start time](/docs/perf-mon/app-start-foreground-background-traces)), and\ndata for [HTTP/S network requests](/docs/perf-mon/network-traces?platform=ios).\n\nUse Swift Package Manager to install and manage Firebase dependencies.\n| Visit [our installation guide](/docs/ios/installation-methods) to learn about the different ways you can add Firebase SDKs to your Apple project, including importing frameworks directly and using CocoaPods.\n\n1. In Xcode, with your app project open, navigate to **File \\\u003e Add Packages**.\n2. When prompted, add the Firebase Apple platforms SDK repository: \n\n```text\n https://github.com/firebase/firebase-ios-sdk.git\n```\n| **Note:** New projects should use the default (latest) SDK version, but you can choose an older version if needed.\n3. Choose the Performance Monitoring library.\n4. Add the `-ObjC` flag to the *Other Linker Flags* section of your target's build settings.\n5. When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.\n\nNext, configure the Firebase module:\n\n1. Import the `FirebaseCore` module in your `UIApplicationDelegate`, as well as any other [Firebase modules](/docs/ios/setup#available-pods) your app delegate uses. For example, to use Cloud Firestore and Authentication: \n\n SwiftUI \n\n ```swift\n import SwiftUI\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Swift \n\n ```swift\n import FirebaseCore\n import FirebaseFirestore\n import FirebaseAuth\n // ...\n \n ```\n\n Objective-C \n\n ```objective-c\n @import FirebaseCore;\n @import FirebaseFirestore;\n @import FirebaseAuth;\n // ...\n \n ```\n2. Configure a [`FirebaseApp`](/docs/reference/swift/firebasecore/api/reference/Classes/FirebaseApp) shared instance in your app delegate's `application(_:didFinishLaunchingWithOptions:)` method: \n\n SwiftUI \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Swift \n\n ```swift\n // Use Firebase library to configure APIs\n FirebaseApp.configure()\n ```\n\n Objective-C \n\n ```objective-c\n // Use Firebase library to configure APIs\n [FIRApp configure];\n ```\n3. If you're using SwiftUI, you must create an application delegate and attach it to your `App` struct via `UIApplicationDelegateAdaptor` or `NSApplicationDelegateAdaptor`. You must also disable app delegate swizzling. For more information, see the [SwiftUI instructions](/docs/ios/learn-more#swiftui). \n\n SwiftUI \n\n ```swift\n @main\n struct YourApp: App {\n // register app delegate for Firebase setup\n @UIApplicationDelegateAdaptor(AppDelegate.self) var delegate\n\n var body: some Scene {\n WindowGroup {\n NavigationView {\n ContentView()\n }\n }\n }\n }\n \n ```\n4. Recompile your app.\n\n| **Note:** When you add Performance Monitoring to your app, the Remote Config SDK is included as a dependency. If you already use Remote Config, you won't see any difference. However, if you're new to Remote Config, explore the [Remote Config documentation](/docs/remote-config/ios) to learn more about the various features you'll be able to access in your app.\n\n**Step 2**: Generate performance events for initial data display\n\nFirebase starts processing the events when you successfully add the SDK to your\napp. If you're still developing locally, interact with your app to generate\nevents for initial data collection and processing.\n| **Note:** The Performance Monitoring SDK batches events locally then sends them to Firebase periodically (every 30 seconds) or when the app comes back to foreground. So, there's a delay between an app interaction and when Firebase receives the event information from your app.\n\n1. Continue to develop your app using a simulator or test device.\n\n2. Generate events by switching your app between background and foreground\n several times, interacting with your app by navigating across screens,\n and/or triggering network requests.\n\n3. Go to the [*Performance* dashboard](//console.firebase.google.com/project/_/performance)\n of the Firebase console. You should see your initial data display within\n a few minutes.\n\n If you don't see a display of your initial data, review the [troubleshooting\n tips](/docs/perf-mon/troubleshooting?platform=ios#sdk-detected-no-data).\n\n**Step 3** : *(Optional)* View log messages for performance events\n\n1. Enable debug logging, as follows:\n\n 1. In Xcode (minimum v16.2), select **Product** \\\u003e **Scheme** \\\u003e **Edit scheme**.\n 2. Select **Run** from the left menu, then select the **Arguments** tab.\n 3. In the *Arguments Passed on Launch* section, add `-FIRDebugEnabled`.\n2. Check your log messages for any error messages.\n\n3. Performance Monitoring tags its log messages with `Firebase/Performance` so that you\n can filter your log messages.\n\n4. Check for the following types of logs which indicate that Performance Monitoring is\n logging performance events:\n\n - `Logging trace metric: `\u003cvar translate=\"no\"\u003eTRACE_NAME\u003c/var\u003e`, `\u003cvar translate=\"no\"\u003eFIREBASE_PERFORMANCE_CONSOLE_URL\u003c/var\u003e\n - `Logging network request trace: `\u003cvar translate=\"no\"\u003eURL\u003c/var\u003e\n5. Click on the URL to view your data in the Firebase console. It may take a few\n moments for the data to update in the dashboard.\n\nIf your app isn't logging performance events, review the [troubleshooting\ntips](/docs/perf-mon/troubleshooting?platform=ios#app-not-logging-events).\n\n**Step 4** : *(Optional)* Add custom monitoring for specific code\n\nTo monitor performance data associated with specific code in your app, you can\ninstrument [**custom code traces**](/docs/perf-mon/custom-code-traces).\n\nWith a custom code trace, you can measure how long it takes your app to complete\na specific task or set of tasks, such as loading a set of images or querying\nyour database. The default metric for a custom code trace is its duration, but\nyou can also add custom metrics, such as cache hits and memory warnings.\n\nIn your code, you define the beginning and the end of a custom code trace (and\nadd any desired custom metrics) using the API provided by the Performance Monitoring SDK.\n\n\nVisit [Add monitoring for specific code](/docs/perf-mon/custom-code-traces)\nto learn more about these features and how to add them to your app.\n\n**Step 5**: Deploy your app then review results\n\nAfter you've validated Performance Monitoring using the Xcode simulator and one or more\ntest devices, you can deploy the updated version of your app to your users.\n\nYou can monitor performance data in the\n[*Performance* dashboard](//console.firebase.google.com/project/_/performance)\nof the Firebase console.\n\nKnown issues\n\n- Performance Monitoring has known compatibility issues with GTMSQLite. We recommend not using Performance Monitoring with apps that use GTMSQLite.\n- Method swizzling after calling `FirebaseApp.configure()` might interfere with the Performance Monitoring SDK.\n- Known issues with the iOS 8.0-8.2 Simulator prevent Performance Monitoring from capturing performance events. These issues are fixed in the iOS 8.3 Simulator and later versions.\n- Connections established using NSURLSession's `backgroundSessionConfiguration` will exhibit longer than expected connection times. These connections are executed out-of-process and the timings reflect in-process callback events.\n\nNext steps\n\n- Review and run the\n [Performance Monitoring iOS code sample on GitHub](//github.com/firebase/quickstart-ios/tree/master/performance).\n\n- Learn more about data automatically collected by Performance Monitoring:\n\n - Data related to your app's lifecycle, like [app start time](/docs/perf-mon/app-start-foreground-background-traces?platform=ios)\n - Data for [screen rendering](/docs/perf-mon/screen-traces?platform=ios) in your app\n - Data for [HTTP/S network requests](/docs/perf-mon/network-traces?platform=ios) issued by your app\n- [View, track, and filter](/docs/perf-mon/console?platform=ios) your\n performance data in the Firebase console.\n\n- Add monitoring for specific tasks or workflows in your app by\n [instrumenting custom code traces](/docs/perf-mon/custom-code-traces?platform=ios).\n\n- [Use attributes to filter performance data](/docs/perf-mon/attributes?platform=ios)."]]
