问题
I'm building an iOS app with React Native. Doing so, I installed a react-native module and configured my iOS xcode project (cocoapods mainly) following the module tutorial. Now, when I run react-native run-ios, I get this error stack :
Undefined symbols for architecture x86_64:

** BUILD FAILED **
The following build commands failed:
Ld /Users/antoine/R/devlab/ReactNative/medway-twilio/MedwayTwilio/ios/build/Build/Products/Debug-iphonesimulator/React/React.framework/React normal x86_64 (1 failure)
I suspect this is related to the inclusion of libraries and frameworks to the project with xcode, but I'm not sure.
This is a screenshot of my project target/build phases/link binary with libraries panel in xcode :
Where "MedwayTwilio" is my project name
回答1:
Did you configured your CocoaPods dependencies as described in the documentation?
Also, you need to add a dependency on the RCTBatchedBridge subspec (if using 0.46) or RCTCxxBridge (if newer).
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
[...]
'BatchedBridge', # Include if RN = 0.46
'CxxBridge' # Include if RN >= 0.47
]
