Fix iOS Build Issue with gRPC-C++ Module Map File

I am encountering an iOS build error in my project related to the gRPC-C++ module. The error specifically states:

module map file '/black_portal/ios/Pods/Headers/Private/grpc/gRPC-Core.modulemap' not found

This issue appears to be related to CocoaPods and the gRPC library integration in the iOS project. The developer will need to debug and resolve this issue to ensure that the project builds successfully on iOS.

Scope of Work:
1. Debugging the Issue:

Analyze the Podfile and Pod dependencies for potential misconfigurations.
Check the installation and configuration of gRPC-C++ in the project.

2. Resolving the Problem:
Fix the missing gRPC-Core.modulemap issue by either regenerating the module map or correctly linking the library.
Ensure that the Pods are properly integrated and build without errors.

3. Testing the Solution:
Build the iOS project successfully on a Mac development environment.
Verify that the fix does not break any existing functionality.

4. Remote Work:
The developer should be able to work remotely on my machine to resolve the issue using tools like TeamViewer, or similar.

Payment Terms:
Payment will be made only after the issue is fully resolved and the iOS project builds successfully without any errors.
Timeline:
I need this issue resolved as soon as possible. Please indicate your availability and estimated time to completion when applying.
