react-native use in Swift ,follow up yoga.h not found .

[huangcheng1]

When i use react in swift with cocoapods , found if use_frameworks in podfile, make error : yoga/yoga.h not found .

so i change podfile with :

use_frameworks!

platform :ios, '8.0'

target 'RNSwiftDemo' do

   pod 'React'

end
pre_install do |installer|
   # Yoga exists in two places in the RN source tree. Delete the obsolete one to avoid redefinitions
   `rm -rf ./xxx/React/CSSLayout`
end

post_install do |installer|
   patch_subspecs(installer)
end

def patch_subspecs(installer)
   # patch source and header files
   `find ./xxx/React/React ./xxx/React/ReactCommon ./xxx/React/Libraries \\( -name *.h -o -name *.m -o -name *.mm \\) -print0 | xargs -0 sed -i '' -E 's:<(yoga|jschelpers|cxxreact)/(.*)>:"\\2":g'`
   
   # exclude duplicate symbols
   # https://github.com/facebook/react-native/issues/11502
   installer.pods_project.targets.each do |target|
       next unless target.name == 'React'
       
       source_files = target.source_build_phase.files
       uniqs = source_files.uniq { |f| f.file_ref.path }
       (source_files - uniqs).each { |dup| source_files.delete(dup) }
   end
end

can work on ObjC, but ObjC file must use .mm,

so i guess , cpp cause this problem .

don't work on Swift, even make ObjeC file to middle file.

Solution from @julienfouilhe

You don't need all the above fixes anymore, remove your patch function in your Podfile, remove the postinstall script in your package.json, just put the master branch of react-native in your dependencies and add yoga as a pod dependency and it should work

package.json:

"react-native": "facebook/react-native#master"
Podfile:

react_path = '../node_modules/react-native'
yoga_path = File.join(react_path, 'ReactCommon/yoga')

pod 'React', :path => react_path, :subspecs => [
'Core',
'RCTText',
'RCTImage',
'RCTWebSocket', # needed for debugging
'RCTNetwork'
]
pod 'Yoga', :path => yoga_path
Don't forget to change all your #include "RCT..." to #include <React/RCT...> too

Same issue with react-native 0.42.0-rc.3. Using @julienfouilhe's Podspec fixes it for me.
