React Native iOS build succeeds locally but fails on CI server - ios

Question

I recently updated a React Native project to version 0.59, and the built-in AsyncStorage is now deprecated. So I installed the #react-native-community/react-native-async-storage package instead as advised, and linked the packages by running react-native link #react-native-community/async-storage.
The build now succeeds when running it in Xcode locally. However, when I try to run the build in my CI pipeline in Azure DevOps, it fails during linking:
# ...
▸ Compiling main.m
▸ Linking MyApp
⚠️ ld: directory not found for option '-L/Users/vsts/agent/2.149.2/work/1/s/ios/MyApp/System/Library/Frameworks'
❌ ld: library not found for -lRNCAsyncStorage
❌ clang: error: linker command failed with exit code 1 (use -v to see invocation)
▸ Linking MyApp
⚠️ ld: directory not found for option '-L/Users/vsts/agent/2.149.2/work/1/s/ios/MyApp/System/Library/Frameworks'
❌ ld: library not found for -lRNCAsyncStorage
❌ clang: error: linker command failed with exit code 1 (use -v to see invocation)
** BUILD FAILED **
The following build commands failed:
Ld /Users/vsts/Library/Developer/Xcode/DerivedData/MyApp-asjjausbybqgpsdjodrbvoyzaeqx/Build/Intermediates.noindex/MyApp.build/BetaRelease-iphoneos/MyApp.build/Objects-normal/armv7/MyApp normal armv7

(2 failures)
##[error]Error: /usr/bin/xcodebuild failed with return code: 65
##[section]Finishing: Xcode build, sign and export
Further up it does look like it has been built:
# ...
▸ Building RNCAsyncStorage/RNCAsyncStorage [(Release)]
▸ Check Dependencies
▸ Building library libRNCAsyncStorage.a
▸ Building library libRNCAsyncStorage.a
▸ Copying RNCAsyncStorage.h
▸ Copying RNCAsyncStorageDelegate.h
# ...
Any ideas what might cause this?

Answer 1

Try setting the Deployment Target to 11.0 in Build Settings / Deployment / iOS Deployment Target.
What might be happening
I was having the exact same issue with a different library and this worked for me.

Answer 2

Adding this ${PODS_CONFIGURATION_BUILD_DIR}/RNCAsyncStorage to Library Search Paths worked for me.
