Para ahorrar energía, Firebase In-App Messaging solo recupera los mensajes desde el servidor una vez al día. Esta acción puede dificultar las pruebas, de manera
que Firebase console te permite especificar un dispositivo de prueba que muestra mensajes
según la demanda.
Ese dispositivo de prueba se determina mediante un FID.
Para encontrar el FID de la app de prueba, busca la salida
de la consola cuando la ejecutes.
En Android, el mensaje suele ser como el siguiente ejemplo:
I/FIAM.Headless: Starting InAppMessaging runtime with Installation ID YOUR_INSTALLATION_ID
En iOS, ejecuta la app con el argumento del comando del entorno de ejecución -FIRDebugEnabled:
Con el proyecto de Xcode abierto, selecciona Product > Scheme > Edit scheme
en la barra de menú superior.
Abre la pestaña Arguments en el diálogo emergente.
Haz clic en + Add items en Arguments Passed On Launch.
Escribe “-FIRDebugEnabled” en el campo que acabas de crear.
Haz clic en Close y ejecuta la app.
Cuando la app se abra, busca la siguiente línea en los registros de la consola de Xcode:
[Firebase/InAppMessaging][I-IAM180017] Starting InAppMessaging runtime with Firebase Installation ID YOUR_INSTALLATION_ID
Envía un mensaje a tu dispositivo de prueba
Una vez que hayas iniciado tu app en el dispositivo de prueba y tengas su
ID de instalación de Firebase (FID), puedes probar la configuración de Firebase In-App Messaging enviando
un mensaje de prueba de la siguiente manera:
Si esta es tu primera campaña, haz clic en Crear la primera campaña.
Selecciona Mensajes desde la app de Firebase y haz clic en Crear.
De lo contrario, en la pestaña Campañas, haz clic en Campaña nueva.
Selecciona In-App Messaging.
Ingresa un Título para tu primer mensaje.
Haz clic en Probar en tu dispositivo.
Ingresa el ID de instalación de Firebase de tu app en el campo
Agregar un ID de instalación.
Haz clic en Probar para enviar el mensaje.
Firebase In-App Messaging envía el mensaje de prueba apenas haces clic en Probar. Para ver el
mensaje, debes cerrar la app y volver a abrirla en el dispositivo de prueba.
Para confirmar si el dispositivo es de prueba, busca uno de los siguientes
mensajes de registro.

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 In-App Messaging library.\n4. Add the `-ObjC` flag to the *Other Linker Flags* section of your target's build settings.\n5. To use In-App Messaging, you must [enable Google Analytics](//support.google.com/firebase/answer/9289399#linkga) in your Firebase project and add the Firebase SDK for Google Analytics to your app. You can select either the library without IDFA collection or with IDFA collection. See our FAQ on the [latest organization of modules in the Google Analytics for Firebase SDK](/support/faq#analytics-odm2-sdk-refactor-ios).\n6. When finished, Xcode will automatically begin resolving and downloading your dependencies in the background.\n\nNow, initialize the SDK in your app:\n\n1. Import the Firebase module in your `App` struct or `UIApplicationDelegate`, if you haven't yet: \n\n Swift \n\n ```swift\n import Firebase\n ```\n\n Objective-C \n\n ```objective-c\n @import Firebase;\n ```\n2. Also configure a [`FirebaseApp`](/docs/reference/ios/firebasecore/api/reference/Classes/FIRApp) shared instance, typically in your `App`'s initializer or your app delegate's `application(_:didFinishLaunchingWithOptions:)` method, if you haven't yet: \n\n Swift \n\n ```swift\n FirebaseApp.configure()\n ```\n\n Objective-C \n\n ```objective-c\n [FIRApp configure];\n ```\n3. Compile and run your app.\n\n| **Note:** Firebase In-App Messaging requires Firebase version 5.6.0 or higher. If you're having trouble compiling your app, try running `pod update` in your app's project directory. Keep in mind, though, that the command updates all of your app's dependencies, not just Firebase ones.\n\n\u003cbr /\u003e\n\nSend a test message\n\nGet your app's installation ID\n\nTo conserve power, Firebase In-App Messaging only retrieves messages from the\nserver once per day. That can make testing difficult, so the\nFirebase console allows you to specify a test device that displays messages\non demand.\n\n\nThat testing device is determined by a Firebase installation ID provided by the\nFirebase installations service. To find your testing app's installation ID, run the app with the\nruntime command argument `-FIRDebugEnabled`:\n\n1. With your Xcode project open, select **Product \\\u003e Scheme \\\u003e Edit scheme...** from the top menu bar.\n2. Open the **Arguments** tab of the dialog that pops up.\n3. Click **+ Add items** under **Arguments Passed On Launch**.\n4. Enter \"-FIRDebugEnabled\" in the newly-created field.\n5. Click **Close**, then run your app.\n\nOnce your app starts running, look for the following line in the Xcode console's logs: \n\n```scdoc\n[Firebase/InAppMessaging][I-IAM180017] Starting InAppMessaging runtime with Firebase Installation ID YOUR_INSTALLATION_ID\n```\n\n\u003cbr /\u003e\n\nSend a message to your testing device\n\nOnce you've launched your app on the testing device and you have its\nFirebase installation ID (FID), you can try out your Firebase In-App Messaging\nsetup by sending a test message:\n\n1. In the Firebase console, open the [Messaging page](https://console.firebase.google.com/project/_/messaging/).\n2. If this is your first campaign, click **Create your first campaign** .\n 1. Select **Firebase In-App messages** and click **Create**.\n3. Otherwise, on the **Campaigns** tab, click **New campaign** .\n 1. Select **In-App Messaging**.\n4. Enter a **Title** for your first message.\n5. Click **Test on Device**\n6. Enter your app's Firebase installation ID in the **Add an installation ID** field.\n7. Click **Test** to send the message.\n\nFirebase In-App Messaging sends your test message as soon as you click **Test**. To see the\nmessage, you need to close, then reopen the app on your testing device.\n\nTo confirm whether your device is a test device, look for the following\nlog message: \n\n```\n[Firebase/InAppMessaging][I-IAM180017] Seeing test message in fetch response.
