CocoaPods Could Not Find Compatible Versions for "Firebase/CoreOnly": Easy Solutions

👋 Hey there! Are you facing an issue with CocoaPods while trying to update your Flutter package? Don't worry, you're not alone! Many developers have encountered the "CocoaPods could not find compatible versions for pod 'Firebase/CoreOnly'" error. In this blog post, I'll guide you through the common issues causing this problem and provide easy solutions to get your iOS working smoothly again. Let's dive in! 💻🔥

Understanding the Issue

So, you've updated your Flutter package to the latest versions and now your iOS app is misbehaving. When you try to update your pods, CocoaPods throws this frustrating error at you:

[!] CocoaPods could not find compatible versions for pod "Firebase/CoreOnly":
In Podfile:
cloud_firestore (from `.symlinks/plugins/cloud_firestore/ios`) was resolved to 0.0.1, which depends on
Firebase/Firestore (~> 6.0) was resolved to 6.0.0, which depends on
Firebase/CoreOnly (= 6.0.0)

cloud_functions (from `.symlinks/plugins/cloud_functions/ios`) was resolved to 0.0.1, which depends on
Firebase/Functions (~> 5.18) was resolved to 5.18.0, which depends on
Firebase/CoreOnly (= 5.18.0)

Seems like the dependencies required by Firebase pods are causing compatibility issues, specifically with the "Firebase/CoreOnly" pod. Let's move on to the solutions that can help you resolve this hiccup. 🛠️

Solution 1: Update Your pubspec.yaml

Head over to your pubspec.yaml file and check the versions of your Firebase-related dependencies. Make sure they're compatible with each other. In your case, the versions mentioned are as follows:

firebase_core: "^0.4.0"
firebase_auth: "^0.11.0"
firebase_analytics: "^3.0.0"
cloud_firestore: "^0.11.0+1"
cloud_functions: "^0.3.0"
firebase_storage: "^3.0.0"
firebase_messaging: "^5.0.1"

You can try bumping up/down the versions of these packages to ensure compatibility. For instance, you can try changing cloud_firestore to a version that works with the Firebase/CoreOnly version mentioned in the error.

Solution 2: Cleaning and Building

It's always a good idea to clean and rebuild your project to ensure a clean slate. In your terminal, execute the following commands:

flutter clean
flutter build ios

This will clean up any built artifacts and rebuild your iOS app. It might just do the trick!

Solution 3: Updating CocoaPods

Updating CocoaPods to the latest version can resolve compatibility issues, including our current problem. Run the following commands in your terminal:

pod install
pod update
pod repo update
pod install --repo-update

This will update your CocoaPods and fetch the latest versions of your dependencies. Give it a shot!

Solution 4: Setting the iOS Deployment Target

Sometimes, setting the iOS deployment target explicitly can help resolve conflicts. In your Podfile, ensure that the following line is present:

platform :ios, '12.1'

Additionally, double-check if you've set the same deployment target in Xcode as your build target. Exact match of deployment targets can save the day!

Wrapping Up 🎁

I hope these solutions help you get rid of the "CocoaPods could not find compatible versions for pod 'Firebase/CoreOnly'" error and bring back the harmony between your Flutter package and your iOS app. Remember, software development is a journey filled with unexpected challenges, but having the right solutions always makes it worthwhile.
