FirebaseApp.configure(options: options) not loads data when passing FirebaseOptions

Describe your environment

• Xcode version: 8.3.3
• Firebase SDK version: 4.1.1
• Library version: 4.0.6
• Firebase Product: core

Describe the problem

In my app, I have more targets and configurations which require more GoogleServices-Info.plists. I have them all downloaded from firebase console after registering new apps.

On app launch, I am trying to load FirebaseOptions from plist at file path via FirebaseOptions(contentsOfFile: plistPath). Finding plistPath via Bundle.main.path(forResource: plistName, ofType: "plist") (every plist have different name). Although path to plist is found and init is returning FirebaseOptions instance, returned instance is empty.

FirebaseApp.configure(options: options) is then complaining about not finding plist named GoogleService-Info.plist.

Steps to reproduce:

PlistName is different than GoogleService-Info.

guard let plistPath = Bundle.main.path(forResource: plistName, ofType: "plist") else {
    fatalError()
}
         
guard let options = FirebaseOptions(contentsOfFile: plistPath) else {
    fatalError()
}
        
FirebaseApp.configure(options: options)

The plist file must be named GoogleService-Info.plist.

If you have multiple, an option is to put them in different folders.

And is there any reason why it should be named exactly like that? The init(contentsOfFile:) could parse any plist, if given in a right path.

I don't think it must be named "GoogleService-Info.plist". Can you check whether the plist file is in the correct bundle or linked properly?
Can you double check with the code below?
[[NSDictionary dictionaryWithContentsOfFile:plistPath]

[ashhanai]

[[NSDictionary dictionaryWithContentsOfFile:plistPath] works properly. Now I noticed, that FirebaseOptions init works just fine, but FirebaseApp.configure(options: options) cannot handle the passing options and is trying to find "GoogleService-Info.plist" anyway.

So it is a different issue after all.

[ashhanai]

BTW this is console output after FirebaseApp.configure(options: options) call.

<Error> [Firebase/Core][I-COR000012] Could not locate configuration file: 'GoogleService-Info.plist'.

Currently, Firebase Analytics depends on the GoogleService-Info.plist file internally, so that's the issue you're seeing. It's something we're working on, I don't believe there's a workaround for you unfortunately.

[paulb777]

FirebaseCore is checking for GoogleService-Info.plist by name at https://github.com/firebase/firebase-ios-sdk/blob/master/Firebase/Core/FIROptions.m#L103

[ashhanai]

@paulb777 I believe that this check is executed only when you are loading default plist, than it should be named "GoogleService-Info.plist"

@ryanwilson Ok, thank you for this insight :)

[baolocdo]

If it doesn't pass the Options from the plist, then the options is probably wrong. Did you rename the GoogleService-Info.plist that you downloaded from the Firebase dashboard? Did you see any logs in this init: https://github.com/firebase/firebase-ios-sdk/blob/master/Firebase/Core/FIROptions.m#L206

[baolocdo]

Sorry, I have just noticed the log @ashhanai gave us:

[Firebase/Analytics][I-ACS025020] Analytics requires Google App ID from GoogleService-Info.plist. Your data may be lost. Google App ID has been changed. Original, new ID: (nil), 1:625184029135:ios:f8b3e130939c8434

So it looks like the GoogleService-Info.plist was parsed just fine. There is no problem with Firebase Core.
Now, Analytics has such error message because it requires a static plist file instead of run-time options. We deliberately output the message to let you know that there could be some events very early in the app life cycle that requires the Google App ID, so you potentially miss some data.
In conclusion, we recommend to have a static GoogleService-Info.plist file (https://firebase.google.com/docs/ios/setup)

Does that mean we can not use multi config files in our projects (each file for an environment)?

You can, you just may miss out on very early analytics info.
