Flutterfire: [Firestore] Unable to run any fetch on iOS (Simulator)
I'm trying to run on iOS a Flutter app that works perfectly on Android, but it crashes as soon as it arribes to any get(). It does not return any Flutter error, just crashes the app.
The exact line that is causing the issue is:
await Firestore.instance.collection('users')
.document(user_id).get();
(I have a print just before and after this line, so even I have no error reports from Flutter I know it's this line).
If I run the same code on Xcode directly it throws this error:
Thread 32: EXC_BAD_ACCESS (code=1, address=0xffffffffffffffc0)
which, by itself, says nothing to me...
The device system.log also says nothing interesting, just outputs this line when the app crashes and closes: Service exited due to SIGKILL
Other Firebase services like Phone Auth are working, so I don't think is something related to the configuration steps.
The whole output from Xcode is the following:

I thought it could have something to do with line 2, but adding the line Firebase.configure() to AppDelegate solves this line but the crash persists. I simply removed the line because I haven't read about it on official documentation.
To Reproduce
Steps to reproduce the behavior:
- Install firebase for flutter using pub.dev step by step.
- Try to get some documents from firecloud.
Expected behavior
The app does not crash and I get everything working as it works on Android :)
Additional context
I'm using Firebase Auth with phone auth, I've configured everything necessary to make it work with phone auth and it's working fine.
I'm trying to run this app on an iPhone 11 simulator as I don't have a physical iPhone yet.
I've tried the always recommended flutter clean command, deleting Podfile and Podfile.lock so flutter recreates it, redownloading GoogleService-Info.plist, etc...

I would gladly give you all any additional info required to make this work. It's been a week trying to solve this and nothing seem to work.
Thank you!

Hi @sajunt4
Please execute following from root of your ios folder and alsoe make sure you've firebase in your. AppDelegate
pod init
pod install
pod update
and try again
If the problem perisist, your flutter run --verbose and a complete reproducible minimal code sample,
Thank you

Hello again!
I've tried what you said @TahaTesser but still nothing moving in the right direction.
Running flutter run --verbose gives us no useful info. Everything goes well during the build and as soon as we arribe to the line told on first post, and the app closes suddenly.
Today I've tested it in a physical iPhone and running it though Xcode gave us some more info about the moment the app breaks:
Runner[752:107548] *** Assertion failure in void firebase::firestore::core::FirestoreClient::Initialize(const firebase::firestore::auth::User &, const firebase::firestore::api::Settings &)(), /Users/taco/StudioProjects/TACO/ios/Pods/FirebaseFirestore/Firestore/core/src/core/firestore_client.cc:180

So... The error has something to do with opening a database... But is a local file? Nothing to do with my Firestore db?
Some permission error? I'm not near an expert in iOS to guess what's happening.
Any help would be appreciated.
Thank you!

Hey, as part of our on-going work for #2582 we managed to repro this issue and it has been resolved in our Firebase Firestore rework (#2913) - which has now been merged into master. We'll look at publishing some prereleases in the next few days. Thank you
