Can't build ipa for Flutter project [CocoaPods could not find compatible versions for pod "GoogleAppMeasurement":]

Question

I’ve spent days stuck on this. I’ve tried many flutter pub and pod commands but nothing works. I've also deleted the pods folder and re-added the firebase-ios-sdk.

I keep seeing this :

  In Podfile:
    firebase_analytics (from `.symlinks/plugins/firebase_analytics/ios`) was resolved to 9.1.12, which depends on
      Firebase/Analytics (= 9.2.0) was resolved to 9.2.0, which depends on
        Firebase/Core (= 9.2.0) was resolved to 9.2.0, which depends on
          FirebaseAnalytics (~> 9.2.0) was resolved to 9.2.0, which depends on
            FirebaseAnalytics/AdIdSupport (= 9.2.0) was resolved to 9.2.0, which depends on
              GoogleAppMeasurement (= 9.2.0)

    google_mobile_ads (from `.symlinks/plugins/google_mobile_ads/ios`) was resolved to 0.0.1, which depends on
      Google-Mobile-Ads-SDK (= 8.13.0) was resolved to 8.13.0, which depends on
        GoogleAppMeasurement (< 9.0, >= 7.0)

So I got desperate, deleted the whole ios folder and then run flutter create . it regenerated everything and then I run flutterfire configure. Everything seemed fine but I still can't build or run the app targeting ios. I think somehow, xcode is preserving some settings or files and pod cache clean is not even deleting that. What should I delete/nuke in xcode? I'm tired.

Podfile :

platform :ios, '12.0'

# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
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

I've added that now but it's generated, the only think I usually do is to uncomment the ios version to set it to 12 — Nana Kwame, Jul 04 '22 at 21:20

[Edit] google_mobile_ads 2.0.0 has been released to fix this issue

So I found the solution. After staring at Google-Mobile-Ads-SDK for hours I thought why not just manually change the version in the .symlinks folder. I did not work and I got some error about some missing credential. So then I searched for google_mobile_ads ios and found out that the latest version available is so high up. The maximum version flutter uses is from 2021‑11‑17 last year. My guess is there might be trouble migrating it to SDK v9 (I don't know what that is). Anyways that's just a theory, I don't know much about iOS plugins.

Now the solution, I figured at least someone on github has had this same issue and I was right google_mobile_ads it's a p1 issue so hopefully it'll be fixed soon. For now, just replace the dependency like this:

  google_mobile_ads:
    git:
      url: https://github.com/googleads/googleads-mobile-flutter
      ref: 356875362ddb2ac2e0056385d2729c093722fb8d
      path: packages/google_mobile_ads

And it'll work like @jonafeucht on github said. It's a workaround but I've found no isssues with it so far. Although I had to fix a few other issues I created for myself in an attempt to get the project to run.

Same error, I'm thinking it's related to cocoapods persisting some info but I don't have any native ios dev experience – Nana Kwame Jul 04 '22 at 21:51
Please take a backup of your project. Run pod deintegrate and pod install – Kaushik Chandru Jul 04 '22 at 22:10
Ok, will do and see what happens – Nana Kwame Jul 04 '22 at 22:13
Update: didn't work – Nana Kwame Jul 05 '22 at 00:12
Are you getting the same error? – Kaushik Chandru Jul 05 '22 at 05:36
Yes it's the same error – Nana Kwame Jul 05 '22 at 13:46
One other solution is to create a new project and add dependencies and lib in it and build it again. – Kaushik Chandru Jul 05 '22 at 13:57
I've the exact same issue, spent one day trying to solve this, did you find a solution ? – Jerome Jul 05 '22 at 16:57

As you can see the culprit is firebase_analytics. The moment I removed this package, the code is working fine.

Once you remove firebase_analytics package.

Delete ios/Pods folder
Delete ios/Podfile.lock

and run these commands

flutter clean
flutter pub get
flutter run

Hope it helps.

Yes it works but what if you need firebase_analytics in your project? – Nana Kwame Jul 07 '22 at 19:43
It is expected to have a new release in a few days. Keep an eye out. – Waheed Akhtar Jul 08 '22 at 09:38
