Remove React dependency

Summary

Version	v0.26.4
Affected OS	iOS
OS Version	iOS 12, RN 0.58.5

Current behavior

Pod::Spec.new do |s|
  s.name         = "RNDeviceInfo"
  s.version      = "0.21.5"
  s.summary      = "Device Information for react-native"

  s.homepage     = "https://github.com/rebeccahughes/react-native-device-info"

  s.license      = "MIT"
  s.authors      = { "Rebecca Hughes" => "[e-mail]" }
  s.ios.deployment_target = '8.0'
  s.tvos.deployment_target = '10.0'

  s.source       = { :git => "https://github.com/rebeccahughes/react-native-device-info.git" }

  s.source_files  = "ios/RNDeviceInfo/*.{h,m}"

  s.dependency 'React'
end

please remove dependency of react - still appears - is it not removed yet?

Project build is failing due multiple versions of react

Expected behavior

Please remove s.dependency 'React'

Okay, I’m learning through development on my own project how this whole Pod thing works. @guhungry thank you so much for the information here, it was a big help.

I believe the Pod contents @guhungry recommends are the standard and are correct, with the addition of the React (and maybe yoga) remove snippet that you frequently see. I have this working locally and it’s stable as I add/remove pods and link other modules. I think the react-native-camera doc guidance is sufficient and we could include as ios troubleshooting but with our module name:

You may need to adjust your Podfile like this if you use Cocoapods and have undefined symbols or duplicate React definitions

target 'yourTargetName' do
  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge', # Include this for RN >= 0.47
    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket', # Needed for debugging
    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
    # Add any other subspecs you want to use in your project
  ]

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  # Third party deps podspec link
  pod 'react-native-info', path: '../node_modules/react-native-device-info'

end

# if you see errors about React duplicate definitions, this fixes it. The same works for yoga.
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end

I’d like to add this to docs and close this. Can someone read through and make sure I’m not crazy? Thanks!

1. then npm install --save react-native-device-info and react-native link react-native-device-info
2. then cd ios && pod install -> this will install react 0.11.0

It was my understanding that if you are using podfiles you should not link?

You almost always link native libraries with react-native link regardless of your project setup (pod or project). If react-native link detect pod will try to link with Podfile first or else via project file. But for pod to work properly you must install React native via Podfile too. And also remove React dependencies from project file too or else it will crash with each other.

It’s one way or another for linking if you use pod all native libraries need to link with pod.
