Azure CI pipeline build error while building Xcode project

I am trying to set up a CI pipeline using Azure DevOps and i am getting an error as follows while running the pipeline in the xcode section:

'FirebaseCore/FirebaseCore.h' file not found
#import <FirebaseCore/FirebaseCore.h>

'FirebaseCore/FirebaseCore.h' file not found
#import <FirebaseCore/FirebaseCore.h>

** BUILD FAILED **

The following build commands failed:
    CompileSwift normal arm64
    CompileSwiftSources normal arm64 com.apple.xcode.tools.swift.compiler
(2 failures)
##[error]Error: /usr/bin/xcodebuild failed with return code: 65
Finishing: Xcode

A small part of my podfile is as follows:

#Firebase
  pod 'Firebase/Analytics'
  pod 'Firebase/Auth'
  pod 'FirebaseInstanceID', '~> 4.3'

And my azure-pipelines.yml file looks like this:

pool:
  vmImage: 'macos-latest'

steps:
- task: CocoaPods@0
  inputs:
    forceRepoUpdate: true
    projectDirectory: '$(system.defaultWorkingDirectory)'
  displayName: 'pod install using the CocoaPods task with a forced repo update and a custom project directory'
- task: Xcode@5
  inputs:
    actions: 'build'
    scheme: ''
    sdk: 'iphoneos'
    configuration: 'Release'
    xcWorkspacePath: '**/*.xcodeproj/project.xcworkspace'
    xcodeVersion: 'default' # Options: 8, 9, 10, default, specifyPath

I was been trying to get it solved by trying many fixes, but nothing helped. And now i don't know what to do. I would be really satisfied if anyone helps me out in this.
