Framework 'FirebaseFirestoreInternal' not found after installing @react-native-firebase/firestore?

I'm currently developing a React Native Firebase project and recently installed @react-native-firebase/firestore. However, I'm encountering several build errors.

in Xcode:

Framework 'FirebaseFirestoreInternal' not found
Linker command failed with exit code 1 (use -v to see invocation)

in Terminal:

...
warning: Run script build phase '[CP-User] [RN]Check rncore' will be run during every build because it does not specify any outputs. To address this warning, either add output dependencies to the script phase, or configure it to run in every build by unchecking "Based on dependency analysis" in the script phase. (in target 'React-Fabric' from project 'Pods')

The following build commands failed:
        Ld /Users/alexbalinski/Library/Developer/Xcode/DerivedData/MyProject-fvojrknysdvjhsgiaiyvidihehoq/Build/Products/Debug-iphonesimulator/MyProject.app/MyProject normal (in target 'MyProject' from project 'MyProject')
(1 failure)

It's saying FirebaseFirestoreInternal doesn't exist, even though it does.

Podfile (only a part):

target 'TheLifeyApp' do
  config = use_native_modules!
  $RNFirebaseAsStaticFramework = true

  # Firebase modules
  pod 'Firebase', :modular_headers => true
  pod 'FirebaseCore', :modular_headers => true
  pod 'FirebaseFirestore', :modular_headers => true
  pod 'FirebaseCoreInternal', :modular_headers => true
  pod 'FirebaseCoreExtension', :modular_headers => true
  pod 'GoogleUtilities', :modular_headers => true
  pod 'FirebaseFirestoreInternal', :modular_headers => true

  # ...

Steps I’ve Tried:

• Deleting DerivedData and cleaning Xcode build caches

• Running pod update

• Running pod deintegrate && pod install

• Changing the iOS Deployment Target

• Deleting all :modular_headers => true

• Adding $(inherited) to Framework Search Paths

Unfortunately, nothing has resolved the issue. I would greatly appreciate any assistance.

I fixed the error by making sure use_frameworks! :linkage => :static was being used, and deleted all :modular_headers => true:

Replace this:

if linkage != nil
    Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
    use_frameworks! :linkage => :static
end

With this

Pod::UI.puts "Configuring Pod with #{linkage}ally linked Frameworks".green
use_frameworks! :linkage => :static
