After updating cloud_firestore to 4.13.0 and 10.16.0 to 10.17.0 and error start to show up. Please check below

flutter run -v

Long story short, after updating to 10.17.0 it doesnt want to work

[ncooke3]

The result is different now. We get this error:

Lexical or Preprocessor Issue (Xcode): 'FirebaseFirestore/FirebaseFirestore.h' file not found
/Users/russellwheatley/projects/flutterfire/packages/cloud_firestore/cloud_firestore/ios/Classes/Private/FLTFirebaseFirestor>eExtension.h:3:8

How about importing <FirebaseFirestoreInternal/FirebaseFirestore.h> instead? Is it possible you could share a zip of the corresponding project? I'm wondering if the change in error means we got closer to a solution...

[russellwheatley]

@ncooke3 - I like to think we're getting closer!

It is imported already like:

<FirebaseFirestoreInternal/FirebaseFirestore.h>

but the error shows like this:

Lexical or Preprocessor Issue (Xcode): 'FirebaseFirestore/FirebaseFirestore.h' file not found

Here is a zip which demonstrates the error: frameworks_issue.zip

To reproduce, follow these steps:

1. install Flutter on your machine if you don't have it
2. Unzip and from root in terminal, run cd ios.
3. run pod install
4. run xed . to open workspace in Xcode.
5. Run app against simulator
6. You should see the exception in the build logs

Alternatively, if you don't wish to install Flutter on your machine, you could just create an iOS app, add core and performance to your Podfile, and for Firestore, add this line:

pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => "replicate-spm-strategy-18"

Then in AppDelegate, try to import:

#import <FirebaseFirestore/FirebaseFirestore.h>

Note that all header files are missing for Firestore pod. I think this is the key. I'm just not sure why they aren't included 🤔

[ncooke3]

Note that all header files are missing for Firestore pod. I think this is the key. I'm just not sure why they aren't included 🤔

Thanks for the instructions. I had a look, but don't know why they are missing. I agree that this might be the crux to solving it. Despite the podspec in your branch pointing to the firebase-ios-sdk repo, the paths used within the podspec seem to be relative to this repo. For example, the s.source_files glob does not get pulled down when installing the pod, but the s.resource line does. This must mean that the paths are for some reason being evaluated as relative to the podspec rather that relative to the root of the firebase-ios-sdk?

I was suspicious that using vendored_frameworks and source_files within the same podspec may be the issue, so I split them up in a branch of mine and didn't see any change in behavior.

[ueman]

Is that maybe due to the Flutter symlinking of CocoaPods?

[russellwheatley]

@ncooke3 - Something odd is occurring, I essentially copy and pasted the FirebaseFirestore.podspec: https://github.com/firebase/firebase-ios-sdk/blob/main/FirebaseFirestore.podspec

Into the firestore-ios-sdk-frameworks podspec: https://github.com/invertase/firestore-ios-sdk-frameworks/compare/main...replicate-spm-strategy-18

I only changed the summary, description, author & homepage properties which shouldn't impact anything. It still didn't pull in any of the source/header files on these paths into the FirebaseFirestore pod:

main...replicate-spm-strategy-18#diff-722406d904 main...replicate-spm-strategy-18#diff-722406d904

However, when I use the following in our cloud_firestore.podspec here:

s.dependency 'Firebase/Firestore', '10.19.0'

You can see all those source and header files in the FirebaseFirestore pod:

So there is a difference between the two and I'm not sure what that could be 🤔

[russellwheatley]

Is that maybe due to the Flutter symlinking of CocoaPods?

@ueman - I tried on a pure iOS app and I got the same results which eliminates Flutter as a suspect I think.

[paulb777]

One problem with the podspec in the branch above is mixing source and binaries in the same podspec. A better approach might be to rename the current Invertase FirebaseFirestore.podspec to FirebaseFirestoreInternal.podspec and then make a new FirebaseFirestore.podspec that matches Firebase's SPM rule, including Firestore's header mappings from FirebaseFirestoreInternal and depends on the new Invertase FirebaseFirestoreInternal.podspec. I'll see if I can find some time to experiment with this sometime in the next week.

[paulb777]

I have a draft solution in #88 and would appreciate if others would try it out.

[russellwheatley]

Thanks for looking into this issue, @paulb777, much appreciated. I tried out your solution, it built fine but it didn't reduce the build time as intended.

To clarify what occurs; We pull in the Firestore dependency in the FlutterFire cloud_firestore.podspec here: https://github.com/firebase/flutterfire/blob/master/packages/cloud_firestore/cloud_firestore/ios/cloud_firestore.podspec#L36

which would pull in the cocoapods sources (i.e including FirebaseFirestoreInternal). We use firestore-ios-sdk-frameworks to override that pod by updating the Podfile with the following:

pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => "10.19.0"

Instead, that pulls in all FirebaseFirestore xcframeworks which reduces build times.

With what you've outlined in the PR description, it won't override the FirebaseFirestore pod. At build time, I think, it will continue to build FirebaseFirestoreInternal from source.

I updated the Podfile in my Flutter project ios/Podfile with the following:

source 'https://github.com/paulb777/TestFirebaseBinaryStaging.git'
source 'https://cdn.cocoapods.org/'

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))

  pod 'FirebaseFirestoreBinary', '10.18.0'
end

and my build time was still around 4-5 minutes. I might be mistaken but I think whatever solution would need to override the pod FirebaseFirestore. Apologies if I have misunderstood something.

[paulb777]

@russellwheatley Thanks for checking. I added the FirebaseFirestore override back in the PR.

Try replacing pod 'FirebaseFirestoreBinary', '10.18.0' with pod 'FirebaseFirestore', :git => 'https://github.com/paulb777/firestore-ios-sdk-frameworks.git', :tag => '10.18.0' in the Podfile.

[russellwheatley]

@paulb777 - I wonder if we're getting closer. The build cycle on Xcode has what I would expect when using firestore-ios-sdk-frameworks. Usually when importing it roughly has 1200-1400 components to build (as opposed to around 6000 when you use Firestore without firestore-ios-sdk-frameworks):

We still get the same build error:

Looking through the Pods, I see that the relevant header files are present (including FirebaseFirestore.h), but they are in the FirebaseFirestoreBinary Pod:

The FirebaseFirestore Pod only contains a Support Files directory:

I did try and change the import for the build error to:

#import <FirebaseFirestoreBinary/FirebaseFirestore.h>

But the FirebaseFirestoreBinary is not available as a directory to import from.

I wonder whether it is possible to include the header files in FirebaseFirestore instead?

[paulb777]

@russellwheatley

Do you see the same error in the Xcode build log?

These are the lines that fixed that import issue in my test: https://github.com/paulb777/firestore-ios-sdk-frameworks/blob/binary-prototype/FirebaseFirestoreBinary.podspec#L20-L21.

I think this is a result of the same error mentioned above, the header files are not being recognised 🤔. That particular error mentioned above is missing from the logs but it is displayed in the left hand panel:

[russellwheatley]

@paulb777 - did you also include performance and/or real-time database? The problem stems when you also include those plugins along with firestore as they also include FirebaseSharedSwift which caused the initial build error.

If you haven't, this command pulls in those dependencies if you run from the flutter project root:

flutter pub add firebase_core cloud_firestore firebase_performance

Also run pod install from the flutter_project_root/ios directory and you should be able to build from Xcode.

[paulb777]

Yes. I confirmed it still builds after adding pod 'FirebasePerformance' to the Podfile.

With the new design, all Swift is built as source, so there should no longer be a conflict. Also, leveldb is always built as source, so the leveldb workaround for RTDB is no longer needed.

[lukemmtt]

@paulb777 's approach in https://github.com/invertase/firestore-ios-sdk-frameworks/pull/88#issuecomment-1906994215 resolves this issue for me. Thank you Paul!

[matt-hall-zory]

As I commented in the Pull Request, this also resolved the issue for me. Thank you again Paul. Looking forward to the merge.

[russellwheatley]

@paulb777 - I was able to successfully build once I created a new Flutter project 🎉 . Thanks for the work.

To everyone else paying attention to this issue, we should hopefully get this resolved in the near future. It's not quite as simple as merging Paul's PR, but we will endeavour to get this working as soon as possible . I will let you know when it is working 🙏

[lukepighetti]

Used to be these frameworks were available within 48 hours (iirc) of a new release. But this one has been broken for me for almost three months. Did something change upstream? It's a very painful developer experience right now.

We were able to pin to firebase_core: 2.21.0 for a few months but now it's being left behind by other dependencies like firebase_auth

[matt-hall-zory]

I saw that Paul's PR was closed without any further info? Is there any update on this?

[mikehardy]

@matt-hall-zory I believe this is still a very active current work area - I don't have specific info to share but at least I personally am interested in fixing it (I love ccache, yes, but I want this to work too). And I'm pretty sure Mike D and Russell and Paul B are all working on it

Usually when Mike D closes stuff it's because he just went and fixed everything, so I have my fingers crossed for that.

@lukepighetti these are built by a scheduled job and they come out just a few hours after upstream firebase-ios-sdk releases things. 10.20.0 was released just recently for instance, on schedule. What you're seeing is this artifact where the build itself is failing, as we're working through with 72 comments here, a couple PRs with lots of comments also, and we think a strategy that will fix it.

Hold tight and this should be sorted soon

[Salakar]

Yes, was planning to reply after some sleep sorry, but Flutter should be working now on SDK 10.19 and 10.20, same integration as originally;

pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '10.19.0'

This was tested by myself and @russellwheatley today and confirmed working for us, please try it out.

React Native has not been tested yet but in theory should work.

Make sure to run pod cache clean --all and rm -rf ios/Pods ios/Podfile.lock if you have any issues.

[josiahsrc]

@Salakar Exciting news!! I tested it out, however, I am unable to pin version 10.19 or 10.20 because the latest version of flutter cloud_firestore doesn't support those versions. Here is the output I'm seeing:

[!] CocoaPods could not find compatible versions for pod "FirebaseFirestore":
  In Podfile:
    FirebaseFirestore (from `https://github.com/invertase/firestore-ios-sdk-frameworks.git`, tag `10.20.0`)

    cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 4.14.0, which depends on
      Firebase/Firestore (= 10.18.0) was resolved to 10.18.0, which depends on
        FirebaseFirestore (~> 10.18.0)

Installing cloud_firestore directly from main doesn't seem to fix the issue either

[russellwheatley]

@josiahsrc - hmmm, I thought we'd cut a release with firebase-ios-sdk 10.19.0 but it appears it hasn't gone out yet. We will be cutting a release today which contains 10.20.0. If you can't wait, you can actually change the version in your Podfile by adding the following variable that is picked up by firebase_core:

# Add the below line to your Podfile
$FirebaseSDKVersion = '10.19.0'

Just remember to remove it when FlutterFire release goes out today so it doesn't pin the firebase-ios-sdk version 👍

[russellwheatley]

I saw that Paul's PR was closed without any further info? Is there any update on this?

@matt-hall-zory We have already updated the codebase with Paul's changes and some other required changes.

[russellwheatley]

Hey FlutterFire folks, we have released the latest cloud_firestore package (depends on latest firebase_core with the latest firebase-ios-sdk version 10.20.0). If you upgrade your FlutterFire packages to the latest version and update this line in your Podfile:

pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '10.20.0'

It should work as intended. Please let me know how it goes and if you encounter any issues!

For any other platforms (i.e. React Native Firebase), could you please test and let me know how it goes? Thanks 🙏

[josiahsrc]

It works! Just tested again with 10.20 and everything worked flawlessly. Hello again, 19 second build times 🤩 Soooooo fast. Thanks @russellwheatley @Salakar @paulb777 and all others who helped in fixing this!

[mikehardy]

This is confirmed working for react-native-firebase as well now.

I believe this is close able, but however if reality contradicts that belief in form of someone with a reproduction where it still doesn't work, obviously we can reopen and keep working away on this one

(fantastic work bringing this one home - @russellwheatley @paulb777 @Salakar - seriously)

[szotp-lc]

Doesn't work for me, FIrebaseFirestoreBinary target is empty, no framework, no files.

But I figured a decent workaround: use a compiled FirebaseFirestoreInternal with its dependencies & regular FirebaseFirestore, this still cuts compilation time significantly.

Here is a relevant part of Podfile for Flutter (for my workaround)

target 'Runner' do
  use_frameworks! :linkage => :static # this line is important
  use_modular_headers!

  pod 'FirebaseFirestoreInternal', :podspec => 'https://gist.githubusercontent.com/szotp-lc/da7c0fe3ed2d0c622fe62348110cb7ef/raw/8e054439082657f9b08e0a0356aa3ef67a90f87b/FirebaseFirestoreInternal.podspec'

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

[mikehardy]

oh no - thanks for the report @szotp-lc - sadly but dutifully reopening

[mikehardy]

@szotp-lc can you post the podfile contents that do not work? Might help to repro

[szotp-lc]

Project.zip

Added a project with build error and screenshot. Notice that abseil framework ins included, but FirebaseFirestore and FIrebaseFirestoreBinary are empty.

[josiahsrc]

@szotp-lc Perhaps it's the static headers and modular headers. This is what I'm using, maybe it will work for you?

target 'Runner' do
  use_frameworks!
  pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '10.20.0'
  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

[russellwheatley]

@szotp-lc can you post the podfile contents that do not work? Might help to repro

On top of this, please show the build output from your terminal 👌

[lukepighetti]

working for me! airdrop from heaven!!

New solution doesn't include FirebaseFirestore.xcframework as vendored_framework so how it could possibly work?

This didn't built at first. Same error as before. I had been using 10.18.0.

Error (Xcode): Undefined symbols:
Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)

But I did update all the relevant Firebase packages and upgraded to 10.20.0 and I was able to get it to build.

[russellwheatley]

Closing out as this issue is resolved. Thank you for the patience 🙏

[felipecastrosales]

I had forgotten to give my feedback on this.

I had been unable to run my application for months due to this issue, and the version bump actually helped me. Thank you so much guys.

[jmw11x]

I have had this issue show up today when adding firebase messaging to the flutter application I have tried all fixes and still am met with the same error. The only fix that worked was making a new flutter project and init firebase with flutter fire then bring in lib folder and import pub all new.
