Firebase Xcode output in console

Question

I have recently installed the Firebase pods into my app as I want to be able to now check users and allow users to sign up.

However, this is what is in the Console:

2016-09-27 22:45:50.248 SampleApp[68417:] Firebase Analytics v.3402000 started 2016-09-27 22:45:50.260785 SampleApp[68417:3132777] subsystem: com.apple.libsqlite3, category: logging, enable_level: 0, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 1, privacy_setting: 2, enable_private_data: 0 2016-09-27 22:45:50.278546 SampleApp[68417:3132701] subsystem: com.apple.BackBoardServices.fence, category: App, enable_level: 1, persist_level: 0, default_ttl: 0, info_ttl: 0, debug_ttl: 0, generate_symptoms: 0, enable_oversize: 0, privacy_setting: 0, enable_private_data: 0 2016-09-27 22:45:50.278 SampleApp[68417:] To enable debug logging set the following application argument: -FIRAnalyticsDebugEnabled (see ....) 2016-09-27 22:45:50.300 SampleApp[68417:] Successfully created Firebase Analytics App Delegate Proxy automatically.

There is more than 3000 chars in this output and SO will not let me post the full output.

I am very new to iOS development and especially Firebase.

The only code I have running in my viewDidLoad is:

if let user = FIRAuth.auth()?.currentUser {
        print("User Signed In")
    } else {
        print("Not logged in")
    }

I do not even know if this is the correct way to check if there is already a user logged in and I cannot begin to fathom what all this info is.

I have tried this: Xcode 8 Console Garbage? but it did not resolve it.

Can someone tell me how to remove this or understand this?

Answer 1

You probably have a mix of 3 types of output

1. Xcode Console "garbage" -- Definitely give that solution you linked to another try. Sometimes you need to delete and re-install your app for it to take, but that will clean up nearly all the stuff that begins with nw_ (And there's a lot of it!)

2. Normal Firebase output. This should be about 8-10 lines or so.

3. A bunch of scary-looking FIRInstanceID warnings. While you can generally ignore these warnings, they are kind of annoying / scary, so I would recommend fixing them by adding KeyChain sharing in your capabilities as described in this post .
