Flutter on IOS: fatal error: module 'cloud_firestore' not found - ios

Question

After searching long hours on github and stack for similar errors, none of the proposed solutions helped me to resolve this error.
I tried quite a few things (a bit out of order):
remove IOS derived data
change firestore package version
flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm -rf ios/Podfile ios/Podfile.lock ios/Pods ios/Runner.xcworkspace
pod init, install and update
uncomment platform :ios, '9.0' from podfile (maybe not linked to this issue)
Here is the error:
** BUILD FAILED **
Xcode's output:
↳
/Users/flo/Mobile/we_ll_see/ios/Runner/GeneratedPluginRegistrant.m:10:9: fatal error: module
'cloud_firestore' not found
#import cloud_firestore;

Answer 1

this is a very bad and unlucky error. After trying to solve this issue for hours, i finally found the solution. The problem is, that your Podfile isn't updating with the pubspec.yaml file. I think, that your Podfile is nearly empty:
target 'Runner' do
use_frameworks!
end
But thats a big problem. This Podfile will be created if you try: $ rm Podfile and then $ pod init.
Here is my solution:
... but before, you have to check something, otherwise my solution probably won't work:
RUN:
$ pod install
If the result of this command is:
There are 0 dependencies from the Podfile and 0 total pods installed.
You can be sure, that this solution works. Otherwise it will also function but maybe you should write me your result of the command line in the comments!!
Now back to the solution...
Step: Update your Podfile with the following code (Please delete the old stuff of the file):
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end
Now the Podfile is updating the pods you wrote down in your podspec.yaml file.
Now you have to sync you podspec.yaml file with the xcode pods, by calling:
$ pod install
Then you will see all you pods downloading. After this you can run your flutter project, by calling flutter run or just in your editor.
Note: The Podfile.lock file lists down the pods and versions of each pod. The 'real' Podfile is only used for the connection between the podspec.yaml file and the real pods. If you look at your Podfile.lock file, you will see, that there aren't any pods written down and that's causing the problem. If there aren't any pods to install, each module (e.g. 'cloud-firestore') won't be found...
I hope this answer helps you, you can ask me in the comments if something didn't work, but i know, that this won't happen :)
Edit for macos:
platform :osx, '10.11'
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path =
File.expand_path(File.join('..', 'Flutter', 'ephemeral',
'Flutter-
Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If
you're running pod install manually, make sure \"flutter pub
get\"
is
executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #.
{generated_xcode_build_settings_path}. Try deleting Flutter-
Generated.xcconfig, then run \"flutter pub get\""
end
require File.expand_path(File.join('packages', 'flutter_tools',
'bin', 'podhelper'), flutter_root)
flutter_macos_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_macos_pods
File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_macos_build_settings(target)
end
end

Answer 2

For me I just update deployment target to the same as define in Pod file.
Note you need to open Runner.xcworkspace not Runner.xcodeproj.

Answer 3

If you are using Android Studio the error might occur if you are creating the Podfile manually.
Flutter runs using just the pubspec.yaml file. You don't have to set up the Podfile by yourself. If you follow the installation guideline on the firestore homepage just skip everything after adding GoogleService-Info.plist file using Xcode.

Answer 4

I tried
rm Podfile
pod init
pod install
but it always showed installed 0 dependencies
then I deleted
podfile.lock
and tried
pod install again
and it installed all project dependencies including cloud_firestore.
and flutter run and flutter build ios worked.

Answer 5

Sharing this in case it helps someone else in the future. I had the same issue as the original poster. I tried all of the solutions suggested above and none of them worked for me. As of the writing of this message, at least 5 different people have reported the same issue in the flutterfire repo on Github but no one has posted a clear solution there either.
What did work for me was deleting the entire ios directory in my Flutter project, then rebuilding it:
flutter create -i swift .
It was very time consuming, but it solved the issue. The 'cloud_firestore' not found error is no longer occurring for me. In addition to rebuilding the ios folder, I had to re-add GoogleService-Info.plist to Runner, re-add icons, re-add signing & capabilities in Xcode, and re-add target properties in Xcode such as privacy usage descriptions, etc.
I'd recommend trying all of the other options mentioned above first, but if like me they do not solve the issue for you, deleting and rebuilding the entire ios folder may be an effective next step.

Answer 6

Make sure you are placing the google services info plist file which you download from firebase into as same folder as info-plist

Answer 7

Remove cocoapods entirely by
sudo gem install cocoapods-deintegrate cocoapods-clean
pod deintegrate
pod clean
rm Podfile
deleting the Podfile/Podfile.lock
Then simply run
flutter run

Answer 8

I also faced the same issue and I tried all the solutions above but none of them worked. Then I tried the following steps and it works.
flutter channel dev
flutter upgrade
flutter run

Answer 9

Well, in my case the issue was the deployment target.
It seems that the default deployment target is 9.0 and Firestore requires a higher deployment target.
I updated my Podfile platform ios, '10.0'
Also in Xcode, from the build settings of the runner project, I changed the deployment target to ios 10.
That worked for me.

Answer 10

I have watched several solutions & now I have got the answer why this is happing.
You can solve this issue in 1 minute.
Just add those lines on Podfile:
target 'Runner' do
pod 'FirebaseFirestore', :git => 'https://github.com/invertase/firestore-ios-sdk-frameworks.git', :tag => '9.4.0' // you have to add this line
...
...
...
...
end
I am using tag version: '9.4.0'. You might need to change this as per you using firebase cloud storage.
Just boom. You solve the problem !!!

Answer 11

, my previous answer was unclear. This was just one of many errors I've got while trying to set up Cloud Firestore, so I didn't go through the whole process.
In order for firebase to work, eventually, you have to follow all of the steps from this page:
https://firebase.flutter.dev/docs/firestore/overview/
If you are having problems with generating the firebase_options.dart file, then you need to follow the steps on this page:
https://firebase.google.com/docs/cli#mac-linux-auto-script
The last step is optional, but it reduces build time, and I really don't know how or why, but it made some of the other errors also disappear...
Step 4. Improve iOS & macOS build times, from this page https://firebase.flutter.dev/docs/firestore/overview/
And of course, don't forget to add dependencies in pubspec.yaml
Ref: https://pub.dev/packages/firebase_core/install
There is also a great comment here about using Firebase.initializeApp()
Ref: https://stackoverflow.com/a/63492262/17626190

Answer 12

For anyone still facing this error, the following worked for me:
I was facing the exact same error. My pod file looked exactly like the one asked in the question
target 'Runner' do
use_frameworks!
end
I solved by doing the following:
Delete the ios folder
in the main directory, run the following
flutter create .
This will generate a new ios folder.
run flutter clean
run flutter pub get
cd ios/ and run pod install
That should install all the pods properly in your ios project now.

Answer 13

None of the answers worked for me so I am adding the one that did.
Replace the contents of your Podfile with the following.
platform :ios, '12.0'
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
def flutter_install_ios_plugin_pods(ios_application_path = nil)
ios_application_path ||= File.dirname(defined_in_file.realpath) if self.respond_to?(:defined_in_file)
raise 'Could not find iOS application path' unless ios_application_path
symlink_dir = File.expand_path('.symlinks', ios_application_path)
system('rm', '-rf', symlink_dir) # Avoid the complication of dependencies like FileUtils.
symlink_plugins_dir = File.expand_path('plugins', symlink_dir)
system('mkdir', '-p', symlink_plugins_dir)
plugins_file = File.join(ios_application_path, '..', '.flutter-plugins-dependencies')
plugin_pods = flutter_parse_plugins_file(plugins_file)
plugin_pods.each do |plugin_hash|
plugin_name = plugin_hash['name']
plugin_path = plugin_hash['path']
if (plugin_name && plugin_path)
symlink = File.join(symlink_plugins_dir, plugin_name)
File.symlink(plugin_path, symlink)
if plugin_name == 'flutter_ffmpeg'
pod 'flutter_ffmpeg/full-lts', :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
else
pod plugin_name, :path => File.join('.symlinks', 'plugins', plugin_name, 'ios')
end
end
end
end
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end
Run pub get
Run pod install

Answer 14

In my case, I have a Mac with Apple Chip, so I have to run pod install with arch -x86_64
So... first configure your platforms, and follow the instructions
flutterfire configure --project=...
Then, add the Firebase Core libraries
flutter pub add firebase_core
Run "flutter run" it will fail
flutter run
So, go to ios folder
cd ios
Edit Podfile and change "platform :ios, '9.0'" to "platform :ios, '11.0'" (or higher)
Then execute
arch -x86_64 pod install --repo-update
And then
flutter run

Answer 15

Replace the contents of your Podfile with the following.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
platform :ios, '9.0'
target 'Runner' do
use_frameworks!
use_modular_headers!
pod 'Firebase/Core'
pod 'Firebase/Firestore'
pod 'Firebase/Analytics'
# flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end

Answer 16

after a while i found out the solution and its quite simple, for anyone who trying to archive and upload flutter app to app store and having the issue of not detecting the Firebase modules please follow these steps:
note: if you have been already trying and you have created podFiles or plist files like google-services.plist please remove them all and start over...
1- make sure when you use mac device that you install flutter SDK and all the necessary tools (VSCode, git, Cocoapods) in case you are using it only for deployment.
2- after setting up your mac device for flutter development open your files on VSCode and leave it open.
3- open XCode and select open a project or file and select the ios folder, or you can open XCode then return to VSCode and right click (Control + Click) on the ios folder and select "open with XCode".
4- go to your Firebase console and open your project, if you have already set-up your project with IOS click on the IOS project and scroll down to find "Download google-services.plist", Otherwise please setup your project for IOS by only installing google-services.plist file and skip the other steps.
5- go to your Downloads or the place that you downloaded the plist file on and drag it to your XCode under the bottom runner folder where your "info" file exist.
6- go to VSCode now and and open the terminal and type cd ios.
7- This step is the magic, on your terminal type flutter pub get, and you will see an auto podFile generated on your ios folder !.
8- now type pod install and congratulations all pods and dependencies for Firebase are installed correctly.
9- Close XCode and re-open it choosing the ios folder you will notice a change on the files structure.
10- from products tap above choose destination to "any ios device" then Archive.
have a good day !

Answer 17

Your issue not may be a big situation. You might be opening the wrong file in the wrong folder.
So, check out from which folder you are opening in Xcode as Runner.xcworkspace.
You need to from Runner.xcworkspace folder not Runner.xcodeproj.

Answer 18

For my case I just changed the pod file platform ton 12.0 and the Xcode platform to 12.0. This is after adding the following code to pod file
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'NO'
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end
end
