Firestore networking error when reading but is able to write documents
Description
When trying to read documents in a collection or setting up a listener, I am getting a networking error. However, I am able to write and create docs so network is available. I see the created docs via the console.
Read error occurs on both simulator (iPhone 17.5) and device (iPad 18.1 Beta)

Found a Stackoverflow thread reporting exact same issue as mine -> https://stackoverflow.com/questions/78929426/swiftui-with-firebasefirestore
Reproducing the issue
It's a very basic project that writes a document to a one level collection and then tries to read an array of docs from that collection and tries to setup a snapshot listener.
Firebase SDK Version
11.2.0
Xcode Version
15.4
Installation Method
Swift Package Manager
Firebase Product(s)

Hi @aashishpatil, thank you for reporting this issue. Could you please try these?
- Set logLevel to "kLogLevelDebug" and run the app again
- Check firestore rules, is there any rules that could forbid reading?
- Provide a minimal repro app, it would be easier if we can reproduce the bug at our end
- Is the error happening in each run or intermittently?
- Could this be simulator/device specific: Xcode 14 vs 15, iOS vs ipadOS, alpha vs beta?
Hey @aashishpatil. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.
If you have more information that will help us get to the bottom of this, just add a comment!

Here is the log after setting debug.
There aren't any rules - confirmed. It's able to write successfully but a read immediately after fails with the network error which is odd since write just worked.
Error is consistently happening.
Environment: (I've updated since my original comment) Xcode 16, iPhone Sim iOS 18.0. Firebase 11.3.0
(Error log was captured before update but same issue happens even after update)
having same issue

Environment: Xcode 16, Firebase 11.3.0. Checked on iphone 15, 16, ios 17, 18. Same issue everywhere both in simulator and on physical device
Same issue is happening for both simulator and OS device, on different versions, I think we can rule them out.
Out of curiosity, is this happening to SDK version 10.x.x as well? So far, it is reported on 11.2.0 and 11.3.0
Log has showed that the network is connected and the app have been receiving responses from backend. However, no docs has been sent over.
I am unable to reproduce the same error on my app. Could you please provide a minimal repro app?
To others who reported the same issue: Are you able to see the documents while receiving the erros, or no documents can be seen on the frontend at all?
Issue started appears in all 11.X versions starting with 11.0.0 Latest 10.X version does NOT have the issue Issue happens every time I start the app and the documents actually are loaded despite the errors Debug logs:

@AlexEzzeddine, still no docs being sent over. expected_count { value: 1} indicates that there is one doc in your persistence, so you might be reading it from the cache. Can you clear cache first, and try restarting the app?
here are the logs with cache cleared:

Update: the issue seems to be introduced by the SDK 11.0.0, where it have upgraded the gRPC version. This ticket is brought to related team's attention.
The issue is not reproducible locally. A minimal repro app will be greatly appreciated.
Hey @aashishpatil. We need more information to resolve this issue but there hasn't been an update in 5 weekdays. I'm marking the issue as stale and if there are no new updates in the next 5 days I will close it automatically.
If you have more information that will help us get to the bottom of this, just add a comment!
Since there haven't been any recent updates here, I am going to close this issue.
@aashishpatil if you're still experiencing this problem and want to continue the discussion just leave a comment here and we are happy to re-open this.
Hi, I'm still experiencing the issue with Firebase 11.4.0 and gRPC 1.65.1.
Hi @michallangmajer, is it possible to provide a minimal repro app/code? I have tried locally, but cannot reproduce the issue.
Hi, don't you already have minimum repo, logs and everything else you need from previous conversation with other people? You mentioned here that you're also aware of the issue: https://github.com/firebase/firebase-ios-sdk/issues/13644#issuecomment-2397399940 I will try to put it together
Hi @michallangmajer, user has confirmed that the issue started at the version 11.0.0, which is the version that grpc dependency has been updated. Thus we are suspecting that it is the cause. But we haven't been able to reproduce and debug it at our end.
Hi, having the same issue, everything was working fine for a few days, and a day before yesterday it just stopped working throwing error every time. Tried to create small test app and download data there, it fails as well.

@Dmy-Volokhovskyi, could you please share your test app and repro steps via github repository?
@milaGGL Has anyone attempted to reproduce it?
I just created a project from scratch, initialized Firebase, and queried a document to reproduce it. https://github.com/wellen-ai/firestore-networking-error-repro/tree/main
Only thing missing is the GoogleService-Info.plist
Here are the logs from the run, there are things there that i'm not sure would be relevant but perhaps they are. I added other Firebase dependencies to replicate my main project in case that had something to do with it.
11.6.0 - [FirebaseCore][I-COR000008] The project's Bundle ID is inconsistent with either the Bundle ID in 'GoogleService-Info.plist', or the Bundle ID in the options if you are using a customized options. To ensure that everything can be configured correctly, you may need to make the Bundle IDs consistent. To continue with this plist file, you may change your app's bundle identifier to 'com.welling.Welling'. Or you can download a new configuration file that matches your bundle identifier from https://console.firebase.google.com/ and replace the current one.
11.6.0 - [FirebaseMessaging][I-FCM001000] FIRMessaging Remote Notifications proxy enabled, will swizzle remote notification receiver handlers. If you'd prefer to manually integrate Firebase Messaging, add "FirebaseAppDelegateProxyEnabled" to your Info.plist, and set it to NO. Follow the instructions at:
https://firebase.google.com/docs/cloud-messaging/ios/client#method_swizzling_in_firebase_messaging
to ensure proper integration.

@irwinb , I am still unable to reproduce the error, the app worked fine locally and successfully fetched the doc.
Same for me. Happen when run Listner
let db = Firestore.firestore()
self.listener = db.document(path).addSnapshotListener { document, error in
if let document, let data = document.data() {
handler(data)
} else {
handler(nil)
}
}
I encountered this same error message. In my case, the issue was that the name of the collection in my code didn’t match the one in Firestore. Make sure to carefully check the names of your collections and documents in Firestore before diving into more complex solutions. This could save you a lot of time.
following, getting same error

Hi everyone, there is another issue ticket which is related to grpc version 1.65.x and hard to reproduce as well.
Could you please check your grpc version, and try locking it to others, as suggested on the other ticket, like 1.65.1, 1.65.6-pre1, or 1.65.6-pre2?
I thought the error would be resolved after 11.9.0, but no.
addSnapshotListener code:
func fetchData() {
if listenerRegistration == nil {
listenerRegistration = db.collection("items").addSnapshotListener { (querySnapshot, error) in
guard let documents = querySnapshot?.documents else {
print("No documents")
return
}
print("Mapping \(documents.count) documents")
self.items = documents.compactMap { (queryDocumentSnapshot) -> Item? in
do {
let item = try queryDocumentSnapshot.data(as: Item.self)
print("Document ID: \(queryDocumentSnapshot.documentID)")
print("Document data: \(queryDocumentSnapshot.data())")
return item
} catch {
print("Error decoding item: \(error)")
return nil
}
}
}
}
}
At first the program receives the document data, but then an error occurs. Log:
