Using GoogleMLKit 0.61.0 thru CocoaPods is downgrading Google Firebase libs from the latest one defined in my project to older version detailed below

before MLKit - Firebase/Analytics (6.27.0)
after MLKit  - Firebase/Analytics (6.20.0)

before MLKit - Firebase/Core (6.27.0):
after MLKit  - Firebase/Core (6.20.0):

before MLKit  - nanopb (~> 1.30905.0)
before MLKit  - FirebaseCore (6.8.0):
before MLKit  - FirebaseCoreDiagnostics (~> 1.3)
after MLKit   - nanopb (= 0.3.9011)
after MLKit   - FirebaseAnalyticsInterop (1.5.0)
after MLKit   - FirebaseCore (6.6.4):
after MLKit   - FirebaseCoreDiagnostics (~> 1.2)
after MLKit   - FirebaseCoreDiagnosticsInterop (~> 1.2)

My podfile:

...
  pod 'Firebase/Crashlytics'
  pod 'Firebase/Analytics'
  pod 'Firebase/Performance'
  pod 'GoogleMLKit/BarcodeScanning', '= 0.61.0'. //Latest GoogleMLKit version
  pod 'GoogleMLKit/TextRecognition', '= 0.61.0'
...

As per the changelog it doesn't have any dependency on Firebase, but still when I try to use that it is updating the firebase as well. And we cannot use the older Firebase version because we faced many issues and crashes there

This is the first release of ML Kit as a standalone SDK, independent from Firebase.
This SDK offers all the on-device APIs that were previously offered through the ML Kit for Firebase SDK.

Any help on this will be very appreciate

We just released a patch version 0.61.1 for MLKitCommon CocoaPod. Please install the latest GoogleMLKit and let us know if the issue is fixed.

Update: July 15, 2020: Run pod update.

As pointed out by @Dong Chen, the issue is now fixed with MLKitCommon version 0.61.1.

This looks like a bug in the MLKitCommon pod. It is depending on a version 3.x of GoogleDataTransport and Firebase is several versions later. The CocoaPods installation finds a compatible version of Firebase which is several months old.

  • yeah I believe the issue is on `GoogleDataTransportCCTSupport` since this still on 1.x and Firebase, as you said, is already on 3.x. That's causing the conflict. – Felipe Duarte Jul 14 '20 at 17:21

  • Actually just the `GoogleDataTransport` pod version. `GoogleDataTransportCCTSupport` is no longer used as it has been combined into `GoogleDataTransport` – Paul Beusterien Jul 14 '20 at 17:37
