react-native, error "The Swift pod `FirebaseCoreInternal` depends upon GoogleUtilities" + "dyld: Library not loaded"

에러상황

[!] 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.

새프로젝트에서 위 같은 에러가 발생했다.

use_frameworks를 주석처리하니

dyld: Library not loaded
...

이와 같은 실행 오류가 발생했다.

많은 시행착오를 걸쳐 발견한 해결법은 아래와 같다

 

해결책

 

0) react-native version
version >= 0.70 인 경우 < 0.7 로 변경 (ex 0.65)

 

1) 맥 os 기분, 아래 경로에서 프로젝트 폴더 제거

/Library/Developer/Xcode/DerivedData

 

2) Podfile 확인/수정

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

use_frameworks! :linkage => :static

platform :ios, '12.4'
install! 'cocoapods', :deterministic_uuids => false

target 'myapp' do
  config = use_native_modules!

  # Flags change depending on the env values.
  flags = get_default_flags()

  use_react_native!(
    :path => config[:reactNativePath],
    # to enable hermes on iOS, change `false` to `true` and then install pods
    :hermes_enabled => flags[:hermes_enabled],
    :fabric_enabled => flags[:fabric_enabled],
    # An absolute path to your application root.
    :app_path => "#{Pod::Config.instance.installation_root}/.."
  )

  target 'myappTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable the next line.
  # use_flipper!()

  post_install do |installer|
    react_native_post_install(installer)
    __apply_Xcode_12_5_M1_post_install_workaround(installer)
  end
end

 

3) pod 갱신

Podfile.lock 제거
Pods 폴더 제거

pod install

 

 

4) 실행 및 확인

npm run ios
