❌ pod install fails due to conflicting GoogleMLKit/MLKitCore versions

[JASIM0021]

🐛 Bug Report

pod install fails in the ios directory due to incompatible versions of GoogleMLKit/MLKitCore.

❗ Error Output

⚠️  Something went wrong running `pod install` in the `ios` directory.
Command `pod install` failed.
└─ Cause: CocoaPods could not find compatible versions for pod "GoogleMLKit/MLKitCore":
  In snapshot (Podfile.lock):
    GoogleMLKit/MLKitCore (= 3.2.0)

  In Podfile:
    react-native-mlkit-ocr (from `../node_modules/react-native-mlkit-ocr`) was resolved to 0.3.0, which depends on
      GoogleMLKit/TextRecognition (= 2.6.0) was resolved to 2.6.0, which depends on
        GoogleMLKit/MLKitCore (= 2.6.0)

You have either:
 * changed the constraints of dependency `GoogleMLKit/MLKitCore` inside your development pod `react-native-mlkit-ocr`.
   You should run `pod update GoogleMLKit/MLKitCore` to apply changes you've made.

pod install --repo-update --ansi exited with non-zero code: 1

📦 Environment

• Library version: react-native-mlkit-ocr@0.3.0
• iOS environment with CocoaPods
• Podfile.lock references: GoogleMLKit/MLKitCore (= 3.2.0)

🔧 Steps to Reproduce

1. Install the package via npm/yarn.
2. Navigate to the ios folder.
3. Run pod install.

🧩 Possible Fix

Looks like the version of GoogleMLKit/MLKitCore required by GoogleMLKit/TextRecognition (2.6.0) is incompatible with what's in the lockfile (3.2.0).

A resolution might involve:

• Updating react-native-mlkit-ocr to support the latest GoogleMLKit versions.
• Or guidance on how to downgrade MLKitCore cleanly.

Although this issue is not directly related to the react-native-mlkit-ocr library, I wanted to share a similar issue I encountered in case it helps others facing version conflicts.

I'm using "react-native-mlkit-ocr": "^0.3.0" alongside "@react-native-google-signin/google-signin": "^16.0.0", and I ran into a version conflict with GoogleUtilities/UserDefaults. Here's the error message I got when running pod install:

[!] CocoaPods could not find compatible versions for pod "GoogleUtilities/UserDefaults":
  In Podfile:
    RNGoogleSignin (from `../node_modules/@react-native-google-signin/google-signin`) was resolved to 16.0.0, which depends on
      GoogleSignIn (~> 9.0) was resolved to 9.0.0, which depends on
        AppCheckCore (~> 11.0) was resolved to 11.2.0, which depends on
          GoogleUtilities/UserDefaults (~> 8.0)

    react-native-mlkit-ocr (from `../node_modules/react-native-mlkit-ocr`) was resolved to 0.3.0, which depends on
      GoogleMLKit/TextRecognition (= 2.6.0) was resolved to 2.6.0, which depends on
        MLKitTextRecognition (~> 1.4.0-beta3) was resolved to 1.4.0-beta3, which depends on
          MLKitCommon (~> 5.0) was resolved to 5.0.0, which depends on
            GoogleUtilities/UserDefaults (~> 7.0)

Specs satisfying the `GoogleUtilities/UserDefaults (~> 7.0), GoogleUtilities/UserDefaults (~> 8.0)` dependency were found, but they required a higher minimum deployment target.

To resolve this, I downgraded to "@react-native-google-signin/google-signin": "10.1.2", which is compatible with GoogleUtilities/UserDefaults ~> 7.0. Additionally, I installed the expo-build-properties package and updated my app.json to include the following in the plugins section:

[
  "expo-build-properties",
  {
    "ios": {
      "extraPods": [
        {
          "name": "GoogleUtilities",
          "version": "~> 7.0"
        }
      ]
    }
  }
]

This configuration forced CocoaPods to use GoogleUtilities ~> 7.0, resolving the conflict. I hope this helps anyone facing a similar issue!

I was struggling with these version conflicts too, mostly because the dependencies here are a bit outdated.

I eventually decided to build a fresh package to fix this. Since it uses updated pods, it installs smoothly without conflicts.

It also allows selecting/downloading specific language models and bundling them offline, which was a key requirement for me.
