How to stop Firebase from updating registration status at application startup

Question

When I launch the FireBase application, it logs the status of various Firebase features. Now this is what is being recorded:

Configuring the default app. <FIRAnalytics/INFO> Firebase Analytics v.3200000 started <FIRAnalytics/INFO> To enable debug logging set the following application argument: -FIRAnalyticsDebugEnabled (see ...) <FIRAnalytics/INFO> Successfully created Firebase Analytics App Delegate Proxy automatically. To disable the proxy, set the flag FirebaseAppDelegateProxyEnabled to NO in the Info.plist <FIRInstanceID/WARNING> FIRInstanceID AppDelegate proxy enabled, will swizzle app delegate remote notification handlers. To disable add "FirebaseAppDelegateProxyEnabled" to your Info.plist and set it to NO <FIRAnalytics/INFO> Firebase Analytics enabled 

I looked through the containers and did not find any print statements, since I could also stop them due to the fact that they were written in overtime. Am I launching an application?

Answer 1

You can disable debugging logging with the -FIRDebugDisabled flag.

You can add it to scheme :

• Select the Scheme Toolbar
• Change Scheme
• Select Run
• Click Arguments and add -FIRDebugDisabled

Answer 2

Add FirebaseConfiguration.shared.setLoggerLevel(.min) to FirebaseApp.configure() to achieve the minimum amount of logging.

 func setupFirebase() { FirebaseConfiguration.shared.setLoggerLevel(.min) FirebaseApp.configure() } 

Answer 3

By default, Firebase will log information, errors, and warnings.
Thus, you can set the level of the registrar that you will ever need. If you set for .Error, you will get a minimal log only on errors.

setLoggerLevel before FirebaseApp.configure () as shown below

In Swift 2.3 and Firebase 4

  FirebaseConfiguration.sharedInstance().setLoggerLevel(.Error) FirebaseApp.configure() 

In Swift 3 and Firebase 4

  FirebaseConfiguration.shared.setLoggerLevel(.min) FirebaseApp.configure() 

Answer 4

In my case, to hide the extra part of the console log from Firebase, I did the following:

1. Go to product → scheme → change scheme.
2. On the Arguments tab, under Environment Variables, add OS_ACTIVITY_MODE = disable

• In case you need it, just uncheck the box.
• Disabling OS_ACTIVITY_MODE sometimes also disables logs for all exceptions

Edit : As @ jesus-adolfo-rodriguez said, this is due to Xcode. So if you do not want OSLog in the Xcode console, put the OS_ACTIVITY_MODE environment variable to "disable" in your schema.

Answer 5

By default, Firebase Analytics will only log 4 INFO lines in production + errors / warnings. It should be very small if everything works correctly. Adding -noFIRAnalyticsDebugEnabled will disable DEBUG level logs and will always log ERROR / WARN. If you see any warnings or errors, you probably need to do something to resolve the cause. Some things most likely will not work correctly if warnings / errors are logged. An application that is configured correctly should not log errors / warnings.

Messages marked with FIRInstanceID / * are logged by Firebase Notification, and errors / warnings are always logged.

Swift 4 Firebase 4.10

Set the logging level in your AppDelegate.swift

 FirebaseConfiguration().setLoggerLevel(FirebaseLoggerLevel.min) 

Here is the complete code:

 func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { FirebaseConfiguration().setLoggerLevel(FirebaseLoggerLevel.min) FirebaseApp.configure() return true } 

Answer 7

 FIRConfiguration.sharedInstance().setLoggerLevel(.min) FIRApp.configure() 

In Swift 4

Answer 8

As djabi said, you cannot disable these logs if they are INFO, WARNING or ERROR.

I want to add Nitin Gohel to the answer as I cannot comment: the FirebaseAppDelegateProxyEnabled flag is not intended to disable logs. If you turn it off, you’ll lose tracking auto campaign , and you will need to add methods from FIRAnalytics (AppDelegate) to independently handle the URL and user activity.

To add to the answer from Alex, from https://firebase.google.com/docs/cloud-messaging/ios/client

FirebaseAppDelegateProxyEnabled designed to test your application delegation methods

The FCM API implements the swizzling method in two key areas: mapping the APN token to the FCM registration token and capturing analytic data during message callback processing. Developers who prefer not to use swizzling can turn it off by adding the FirebaseAppDelegateProxyEnabled flag to the apps Info.plist file and setting it to NO (boolean). The relevant areas of the manuals contain code examples, both with and without the swizzling method.
