Flutter_facebook_login: FBSDKCoreKit cocoapods issues with latest version 3

[bizz84]

After updating my Flutter project to version 3.0.0, I'm no longer able to build on iOS.

Error:

    [!] CocoaPods could not find compatible versions for pod "FBSDKCoreKit":
      In Podfile:
        FBSDKCoreKit (= 4.39.1)
        flutter_facebook_login (from `.symlinks/plugins/flutter_facebook_login/ios`) was resolved to 0.0.1, which depends on
          FBSDKCoreKit (~> 5.5)
    Specs satisfying the `FBSDKCoreKit (= 4.39.1), FBSDKCoreKit (~> 5.5)` dependency were found, but they required a higher minimum deployment target.

This is even with setting a minimum deployment target of 11.0 both in the Podfile, and in the Xcode project settings.

flutter doctor:

• No issues found!

pod --version is 1.8.3

Already run pod repo update prior to building the app.

None of this is a problem with version 2.x.

I had the same issue and I fixed it with the following steps:

• flutter clean
• Remove ios/Podfile.lock file
• Go to the Podfile file and changed from platform :ios, '9.0' to platform :ios, '11.0'
• Go to the terminal , ios directory and run pod install
• Run the project again.

Im getting

`[!] CocoaPods could not find compatible versions for pod "flutter_facebook_login":

EDIT: I had forgotten to uncomment the ios target version in the podfile. I feel a little dump now haha

• Go to the Podfile file and changed from platform :ios, '9.0' to platform :ios, '11.0'

• Run the project again.

In my case I had to run pod update first.

In my case, some libs don't support 11.0 and I use
platform :ios, '9.0
then set deployment target in runner.xcsworkspace to 9.0 and it work.

`[!] CocoaPods could not find compatible versions for pod "FBSDKLoginKit":
In Podfile:
FBSDKLoginKit (~> 4.39.1)

flutter_facebook_login (from `.symlinks/plugins/flutter_facebook_login/ios`) was resolved to 0.0.1, which depends on
  FBSDKLoginKit (~> 5.5)

Specs satisfying the FBSDKLoginKit (~> 4.39.1), FBSDKLoginKit (~> 5.5) dependency were found, but they required a higher minimum deployment target.
`

Hello. I have the same issue as described here but it's happening only on the CI
unfortunately the solution from here is a manual one and it's not possible on the CI. Any suggestions how to fix that is there more info what's the reason for this issue in a first place? Thanks

Hi @fannt Indeed you are right. But I just managed to build by changing all references in this file /ios/Runner.xcodeproj/project.pbxproj to:

IPHONEOS_DEPLOYMENT_TARGET = 9.0;

I'm not iOS expert, and I cant warranty it would be future proof. But My azure devops pipeline passed the facebook login plugin issue.

This is what worked for me:

flutter clean
rm -f ios/Podfile.lock
cd ios
pod update # updates all the dependencies
cd -

# retry again 
flutter run
