Firebase iOS Debug Console not logging anything

Question

I have setup firebase in both the console and in the app. Everything configures correctly, and events appear to be logging in the app.

Output to console:

<         


        

Answer 1

Make sure to add ONE DASH before -FIRDebugEnabled

I wasted a whole day making silly mistake having missed that DASH

Hope that doesn't happen to others!

Answer 2

I made it possible by writing the following:

func application(_ application: UIApplication, didFinishLaunchingWithOptions, ...) {
    // some other initialization

    FirebaseApp.configure()
    Firebase.Analytics.setAnalyticsCollectionEnabled(true)
}

Answer 3

Check if you have an ad blocker enabled while visiting the Firebase website.

I had uBlock origin enabled and it would block every page (Dashboard, Events, StreamView, DebugView...) and they'd all be blank.

Everything worked as expected as soon as I whitelisted it.

Answer 4

Make sure to remove the OS_ACTIVITY_MODE:disable from the Environment Variables in your project scheme if you added it at some point.

Answer 5

Try this , This is work for me ,

Follow below steps ,

1.In Xcode, select Product → Scheme → EditScheme.

2.Select Run from left Menu and Select Arguments tab In the Arguments Passed on + option

add -FIRDebugEnabled

For detail debug view follow steps DebugView track Firebase doc

To send an event in XCode project follow code below,

Objective C

[FIRAnalytics logEventWithName:@"share_image"
                    parameters:@{@"name": name, @"full_text": text}];

Swift

Analytics.logEvent("share_image", parameters: ["name": name, "full_text": text])

For events log follow detail steps Log events in Application Firebase doc

Hope this will help someone.

Answer 6

Alternatively you can do that inside your AppDelegate:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {

    var newArguments = ProcessInfo.processInfo.arguments
    newArguments.append("-FIRDebugEnabled")
    ProcessInfo.processInfo.setValue(newArguments, forKey: "arguments")
    
} 

---EXTRA---

And just some thoughts:

Regarding

Firebase.Analytics.setAnalyticsCollectionEnabled(true)

If we inspect the method:

So it's kind of POINTLESS...
