Same issue, Did you get any solution?

[ArtsiomAstrouski]

@Malhar99 I did a complete reinstallation of all dependencies with clearing the cache and it helped

🚨 Issue Resolution Guide: Clearing Pod Dependencies and Reinstalling

Steps to Resolve:

1. Open Terminal:

   • Open the Terminal on your local machine.

2. Navigate to Your Project Directory:

   • Use the cd command to navigate to your project directory.

     cd /path/to/your/project

3. Remove Existing Podfile.lock and Pods Directory:

   • Delete the current Podfile.lock and Pods directory to start with a clean slate.

     rm Podfile.lock
     rm -rf Pods

4. Remove CocoaPods Cache:

   • Clear the CocoaPods cache to avoid any potential caching issues.

     pod cache clean --all

5. Install CocoaPods:

   • If you don't have CocoaPods installed, install it using the following command:

     sudo gem install cocoapods

6. Install Pods:

   • Run the following command to install the dependencies specified in your Podfile:

     pod install

7. Open the Workspace:

   • If you're not already using the .xcworkspace file, open it in Xcode:

     open YourProject.xcworkspace

8. Clean Build:

   • Clean and build your project to ensure a fresh compilation:
     • In Xcode, go to Product > Clean Build Folder.
     • Then, build the project (Command + B).

9. Run Your Project:

   • Run your project to check if the issue is resolved.

10. Verify the Issue Status:

    • Confirm whether the issue still persists. If it does, please provide additional details or error messages for further assistance.

Notes:

• Ensure that you have administrative privileges for certain commands (sudo).
• Verify that your Xcode project is closed before performing these steps.
• Double-check the paths and commands to avoid any typos or errors.

This process should help in clearing existing dependencies and reinstalling them. If the issue persists, provide more details for a more targeted resolution.
