When I run my app in the terminal I get this error:
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 app.xcworkspace.
But when I try to run the app.xcworkspace I get another error:
ld: warning: directory not found for option
'-L-L/Users/josecuetosimancas/Library/Developer/Xcode/DerivedData/app-arkyvclpjmalkpagzxpefttuuars/Build/Products/Debug-iphonesimulator/BoringSSL-GRPC'
ld: library not found for -lBoringSSL-GRPC clang: error: linker
command failed with exit code 1 (use -v to see invocation)
this is my PODFILE:
require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
platform :ios, '11.0'
target 'app' do
config = use_native_modules!
use_react_native!(:path => config["reactNativePath"])
target 'appTests' 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 these next few lines.
use_flipper!
post_install do |installer|
flipper_post_install(installer)
end
end
target 'app-tvOS' do
# Pods for app-tvOS
target 'app-tvOSTests' do
inherit! :search_paths
# Pods for testing
end
end
and my package.json
