Upgrading react-native from version 0.59.9 to 0.71.2 build errors The Swift pod `FirebaseCoreInternal` depends upon `GoogleUtilities`Upgrading react-native from version 0.59.9 to 0.71.2 build errors

While upgrading react-native from version 0.59.9 to 0.71.2, I am facing multiple build errors, no surprise that there is drastic changes happened from 0.59.9 to 0.71.2.

Error

[!] The following Swift pods cannot yet be integrated as static libraries:

The Swift pod FirebaseCoreInternal depends upon GoogleUtilities, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set use_modular_headers! globally in your Podfile, or specify :modular_headers => true for particular dependencies.

Solution (fix) error for FirebaseCoreInternal depends on GoogleUtilities

Add below lines in your pod file

platform :ios, min_ios_version_supported
….

pod ‘Firebase’, :modular_headers => true
pod ‘FirebaseCoreInternal’, :modular_headers => true
pod ‘GoogleUtilities’, :modular_headers => true
