react-native-gesture-handler: IOS build failed 'Undefined symbols for architecture x86_64'

Updated React-Navigation to 3.0.8 and followed the instruction to install the react-native-gesture-handler. after react-native link react-native-gesture-handler i got error when building with react-native run-ios or building in the xCode.

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_RNForceTouchHandler", referenced from:

      objc-class-ref in libRNGestureHandler.a(RNGestureHandlerManager.o)

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

i am using following packages:

  "react-native": "0.57.3",
    "react-native-gesture-handler": "1.0.12",
    "react-navigation": "3.0.8"

How do i fix this? Please help. Appreciate 😃

I was getting the same issue, but after next steps I got it resolved:

Close the Metro bundler
rm -rf ~/Library/Developer/Xcode/DerivedData/*
Product -> Clean Build Folder
Build from xcode

I’ve managed to compile and run the build with the latest 1.0.15 version, both on device and emulator.

"react-native": "0.57.7"
"react-native-gesture-handler": "1.0.15"

@osdnk finally got project compiled in xcode with a clean build. I have to run this first.

rm -rf ~/Library/Developer/Xcode/DerivedData/*

Then building is ok.

However, running react-native run-ios still give me that error. Wondering if that is caused by npm cache?

Downgrading to "react-native-gesture-handler": "1.0.10" works for us.

I changed iOS Deployment Target from 8.0 to 9.0 in RNGestureHandler.xcodeproj and solved for me

xcode build success, but RN failed

building with react-native run-ios or building in the xCode.

delete RN project directory: ${root}/ios/build

Hi, @sliultron Try changing ‘Build System’ to ‘Legacy Build System’. I’ve just made fresh app with react-native init and then linked RNGH and it appears to work fine. Are you using the newest version of Xcode?
