[READ] Step 1: Are you in the right place?

• For issues or feature requests related to __the code in this repository__
  file a Github issue.
  
  
  
  • If this is a __feature request__ make sure the issue title starts with "FR:".
  
  
• For general technical questions, post a question on StackOverflow
  with the firebase tag.
• For general Firebase discussion, use the firebase-talk
  google group.
• For help troubleshooting your application that does not fall under one
  of the above categories, reach out to the personalized
  Firebase support channel.

[REQUIRED] Step 2: Describe your environment

• Xcode version: 10.1 (10B61)
• Firebase SDK version: 5.16.0
• Firebase Component: Using FirebaseAnalytics (5.5.0)
  Using FirebaseAuth (5.3.0)
  Using FirebaseAuthInterop (1.0.0)
  Using FirebaseCore (5.2.0)
  Using FirebaseDatabase (5.1.0)
  Using FirebaseFirestore (1.0.0)
  Using FirebaseInstanceID (3.4.0)

Here is the top part of my podfile:

# Uncomment this line to define a global platform for your project
 platform :ios, '9.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'

pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'GoogleSignIn'


target 'QueueUpShareExtension' do

  # Pods for QueueUpShareExtension
  pod 'Firebase/Core'
  pod 'Firebase/Auth'
  pod 'GoogleSignIn'

end

[REQUIRED] Step 3:

I'm working in an XCode ios Application Extension (Share Extension). I'm able to authenticate just fine but when I try to get documents or add a document within the same method, it's throwing the exception stack below. Does this have something to do with how I'm instantiating FirestoreSettings?

Steps to reproduce:

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

This doesn't have anything to do with how you've instantiating FirestoreSettings, which is entirely unrelated. The issue is that very early in Firestore initialization, we load a certificate bundle. That bundle needs to be available to find with NSBundle.

Your Podfile doesn't actually include FirebaseFirestore or Firebase/Firestore so it's not clear exactly how you're getting Firestore, but you clearly are getting it because your code is compiling :-).

2177 is primarily about how Carthage-based builds run into trouble when the bundle isn't available where the code expects it. If you're using CocoaPods you should be getting the resources you need automatically. In particular, look for gRPCCertificates.bundle in the FirebaseFirestore.framework.

If you see gRPCCerticates.bundle in your build, the next step would be add a call to Firestore.enableLogging(true) and report back the log lines you see related to certificate loading.

Thank you, Gil! Simply adding "pod 'Firebase/Firestore'" to both places in the podfile and then running pod install did the trick! Working perfectly now.

[burkaslarry]

"pod 'Firebase/Firestore'" to both places in the podfile ? I find only one Podfile add get "pod 'Firebase/Firestore'" added. still error

[paulb777]

"Both places" likely means both target specifications within the Podfile.

[wilhuff]

@burkaslarry "Both places in the Podfile" refers back to the Podfile posted in the issue description, where the author happened to include the dependencies twice.
