good time. run ios error Failed
run code react-native run-ios
error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65. To debug build logs further, consider building your app with Xcode.app, by opening reactapp.xcodeproj
** BUILD FAILED **
I've got the same error when run
$ react-native run-ios
My workaround steps:
$ react-native run-ios
Hope this help.
That's because there is a new version of Flipper and React Native might not come with the right one so best is to go in your podfile and add this use_flipper!({ 'Flipper' => '0.74.0' }) then run pod install
If you don't have cocoa pods installed you need to by command sudo gem install cocoapods and run following commands from your project main directory
cd ios
pod install
cd ..
delete build folder from ios
react-native run-ios
if error persists, 1. delete build folder again 2. open the /ios folder in x-code 3. navigate File -> Project Settings -> Build System -> change (Shared workspace settings and Per-User workspace settings): Build System -> Legacy Build System
cd ios
rm -rf build/
cd ..
react-native run-ios
For me this error showed up after upgrading React Native from 0.69 to 0.72.
Suprisingly all that was needed was to:
Remove all the derived data and rebuild:
rm -rf ~/Library/Developer/Xcode/DerivedData && npx react-native run-ios
If still doesn't work then
1. Make sure metro server is stopped and run a full cache clean:
watchman watch-del-all && rm -rf ios/build && rm -rf ~/Library/Developer/Xcode/DerivedData && rm -rf node_modules && yarn install && cd ios && rm -rf Pods && pod install && cd .. && npx react-native run-ios
Note: if pod install fails take a deep looks at the pod errors
2. Attempt to build with Xcode and look deep into any errors triggered at Xcode build process
Additional notes: this question is possibly a duplicate of error Failed to build iOS project. We ran "xcodebuild" command but it exited with error code 65
