iOS: version conflict with Firebase libs

[hnvn]

The current version of this lib is conflicted with the latest version of Firebase libs, here's log:

[!] CocoaPods could not find compatible versions for pod "GTMSessionFetcher/Core":
  In Podfile:
    firebase_storage (from `.symlinks/plugins/firebase_storage/ios`) was resolved to 11.0.1, which depends on
      Firebase/Storage (= 10.0.0) was resolved to 10.0.0, which depends on
        FirebaseStorage (~> 10.0.0) was resolved to 10.0.0, which depends on
          GTMSessionFetcher/Core (~> 2.1)

    mobile_scanner (from `.symlinks/plugins/mobile_scanner/ios`) was resolved to 0.0.1, which depends on
      GoogleMLKit/BarcodeScanning (~> 2.6.0) was resolved to 2.6.0, which depends on
        MLKitBarcodeScanning (~> 1.7.0) was resolved to 1.7.0, which depends on
          MLKitVision (~> 3.0) was resolved to 3.0.0, which depends on
            GTMSessionFetcher/Core (~> 1.1)

[oerni74]

pod repo update
pod update GTMSessionFetcher/Core

solved it for me. However, the problem for me was firebase_auth not firebase_storage.

[peukerjonathan]

pod repo update
pod update GTMSessionFetcher/Core

solved it for me. However, the problem for me was firebase_auth not firebase_storage.

If this does not work try:

rm -rf ios/Pods
rm ios/Pdofile.lock
flutter clean
pod repo update

Then try again.

[kyeshmz]

This did not work for me, sadly so is a PR to update the package spec better?

[bgetsug]

From the pod output, the issue appears to be with the Podspec for MLKitVision. Even the latest version (4.2.0) is still locked to GTMSessionFetcher/Core 1.1. Since the ML Kit SDK appears to be closed source, I amended the open ticket in Google's issue tracker: https://issuetracker.google.com/issues/254418199

[kyeshmz]

Nice catch @bgetsug !

[uzuki-P]

Is there any workaround on this? I try both oerni74 & peukerjonathan solution, still no luck

[PedroTicGal]

Same issue here, tried @oerni74 and @peukerjonathan solutions but no luck.

Currently the next release is planned at the end of Q4.

Will we have to wait a few months for this issue...

[github-brave]

Same issue here, any solution?

I roll-backed firebase_storage version, and it worked around

• firebase_storage: ^11.0.3

• firebase_storage: ^10.3.7

[juliansteenbakker]

I'm almost done with a new update of this package which will introduce some new functions and update the dependencies as well. With these new dependencies, i did not encounter this error.

@bgetsug @MagnusJohansson I cannot access the IssueTracker. Why is that?

[ghost]

I don't know why, but Issue Tracker is now accessible.

Helle guys, I would share with you a possible solution:

1. Create MLKitVision.podspec.json in ios folder taking content from https://github.com/CocoaPods/Specs/blob/master/Specs/8/1/e/MLKitVision/4.2.0/MLKitVision.podspec.json

2. Create MLKitCommon.podspec.json in ios folder taking content from https://github.com/CocoaPods/Specs/blob/master/Specs/c/c/6/MLKitCommon/8.0.0/MLKitCommon.podspec.json

3. Modify in both files the GTMSessionFetcher/Core definition from 1.1 to version 2.1.

4. Inside your Podfile you have to search for "target 'Runner'" and inside it you have to add the following lines:

      pod 'MLKitVision', :podspec => 'MLKitVision.podspec.json'
      pod 'MLKitCommon', :podspec => 'MLKitCommon.podspec.json'

5. Run pod install

6. build the app

That solved my issue.

I hope the same to you.

I'm facing a similar problem, but between MobileScanner and GoogleMLKitTextRecognition.

[!] CocoaPods could not find compatible versions for pod "GoogleMLKit/MLKitCore":
  In Podfile:
    google_mlkit_text_recognition (from `.symlinks/plugins/google_mlkit_text_recognition/ios`) was resolved to 0.5.0, which depends on
      GoogleMLKit/TextRecognition (~> 3.2.0) was resolved to 3.2.0, which depends on
        GoogleMLKit/MLKitCore (= 3.2.0)

    mobile_scanner (from `.symlinks/plugins/mobile_scanner/ios`) was resolved to 0.0.1, which depends on
      GoogleMLKit/BarcodeScanning (~> 2.6.0) was resolved to 2.6.0, which depends on
        GoogleMLKit/MLKitCore (= 2.6.0)

[vikt0r40]

@juliansteenbakker thank you for your effort, does the new version ready or its still in progress?

[juliansteenbakker]

It's still in progress. I'm hoping i can release a new beta version this weekend. You can track the progress in #362

[motucraft]

I have applied the above workaround and referred to the podfile shared here. It worked for me. Thanks to those who shared their information.

I#ve done the same but got this error then with Firebase 10.2.0:

[!] CocoaPods could not find compatible versions for pod "MLKitCommon": In Podfile: MLKitCommon (from MLKitCommon.podspec.json)

MLKitVision (from `MLKitVision.podspec.json`) was resolved to 4.2.0, which depends on

      MLKitCommon (~> 5.0.0)

// edit: works with 3.0.0.beta-1, but this version is a little bit buggy (white square on the topleft when starting the scanner)

[juliansteenbakker]

Hi all, it took a little longer than i wanted but ive published v3.0.0-beta.2 with lots of improvements. Please checkout the changelog for all changes. I myself did not encounter any firebase issues with this version.

[juliansteenbakker]

Besides updating the latest beta version, i've also fixed the current stable version with v2.1.0.

This version updates firebase on iOS to the latest version which fixes this issue.

[motucraft]

Thanks for releasing v3.0.0-beta.2. I have worked with the following versions without problems.

  firebase_core: ^2.3.0
  firebase_auth: ^4.1.3
  cloud_firestore: ^4.1.0
  cloud_firestore_odm: ^1.0.0-dev.41
  firebase_storage: ^11.0.6

[juliansteenbakker]

Well in that case it really is a problem with firebase rather than this plugin.

Ultimately, I recognize that this is the fundamental problem. https://issuetracker.google.com/issues/254418199
