[iOS] Failed building app with Hermes enabled
See original GitHub issueBug Description
Hello, as soon as I enable Hermes on iOS in our Podfile (we are using React Native 0.64) during compilation I got this error:

What should I do?
I simply enabled the flag like this:
use_react_native!(:path => config["reactNativePath"], :hermes_enabled => true)
This is my Podfile:
platform :ios, '11.0'
use_frameworks!
pre_install do |installer|
installer.pod_targets.each do |pod|
if pod.name.eql?('RNPermissions') || pod.name.start_with?('Permission-')
def pod.build_type;
Pod::BuildType.static_library
end
end
end
end
require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
config = use_native_modules!
use_react_native!(:path => config["reactNativePath"], :hermes_enabled => true)

end
def info_post_install(installer)
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
config.build_settings['ENABLE_BITCODE'] = 'YES'
if File.exist?('Pods/Target Support Files/'+target.name+'/'+target.name+'-Info.plist')
config.build_settings['INFOPLIST_FILE'] = 'Target Support Files/'+target.name+'/'+target.name+'-Info.plist'
#config.build_settings['ONLY_ACTIVE_ARCH'] = 'YES'
end
end
end
end
def enable_bitcode_in(config)
cflags = config.build_settings['OTHER_CFLAGS'] || ['$(inherited)']
if config.name == 'Release'
cflags << '-fembed-bitcode'
config.build_settings['BITCODE_GENERATION_MODE'] = 'bitcode'
else
cflags << '-fembed-bitcode-marker'
config.build_settings['BITCODE_GENERATION_MODE'] = 'marker'
end
config.build_settings['OTHER_CFLAGS'] = cflags
end
def enable_bitcode_for(targets)

end
end

end

target.build_phases.each do |build_phase|
if (build_phase.respond_to?(:name) && build_phase.name.eql?('[CP-User] Generate Specs'))
target.build_phases.move(build_phase, 0)
end
end
end
end
end
post_install do |installer|
info_post_install(installer)
enable_bitcode_for(installer.pods_project.targets)
move_targets(installer.pods_project.targets)
end
Hermes version: 0.7.2 React Native version (if any): 0.64.0 OS version (if any): MacOS Big Sur 11.2.3 Platform (most likely one of arm64-v8a, armeabi-v7a, x86, x86_64): N/A
Steps To Reproduce
- Enable Hermes:
use_react_native!(:path => config["reactNativePath"], :hermes_enabled => true) - pod install
- Compile the app
What should I do?
It seems a dependency problem with DoubleConversion framework, but it should work automatically without adding it manually.
Thank you, Marco

Was able to fix React-Core Double conversion link issue by adding the DoubleConversion.framework library under “Link Binary with Libraries” of the React-Core project under Pods.
i am also facing the same problem
but building fails due to errors in React-Core and DoubleConversion
tried the solution mentioned in #23390
by adding DoubleConversion, glog and folly to link binary with libraries build phase it didn’t work
the only sloution with disable hermes and run pod install again that removed the hermes engine and libevent
then xcode was able to compile and build the app without any errors
however that returns the first issue i was trying to escape with all of this first time whenever tries to reload the app from the dev menu or connect to remote debugger the freezes and crash and you can only rebuild it again
error [native] Timed out waiting for modules to be invalidated
so my question is how should i solve this?
