React Native: Multi-Environment/Flavor Setup (App Icon, App Name, GoogleService.json) for iOS [Latest]

Must Follow Android First:
<- ANDROID CONFIGURATION

---

iOS CONFIGURATION:

Step 1:

Open myapp.workspace

xed -b ios 

---

Step 2:

Duplicate myapp in Target section by right click and rename them production and development.

---

Step 3:

Go to Manage Schemes...:

Rename the myapp copyies to development/production

---

Step 4:

Go to Edit Scheme...:

Go to Build
Pre-actions
Select scheme(like development in screenshot)
Click + to add 2✌🏻 "New Run Script Actions"
Select scheme(like development in screenshot in Run script also)

Add this in First Run Scripts:

# Type a script or drag a script file from your workspace to insert its path.
rm "${CONFIGURATION_BUILD_DIR}/${INFOPLIST_PATH}"
echo ".env.development" > /tmp/envfile

Add this in Second Run Scripts:

# Type a script or drag a script file from your workspace to insert its path.
"${SRCROOT}/../node_modules/react-native-config/ios/ReactNativeConfig/BuildXCConfig.rb" "${SRCROOT}/.." "${SRCROOT}/tmp.xcconfig"

DO FOR PRODUCTION SIMILARLY with .env.production

---

Step 5:

Select scheme(like development) and rename Info.plist File

Select new generated myappInfo.plist(1) and rename(2)

---

Step 6: iOS Change App Icon and App Name

Change App name as per scheme in Display Name/ also you can change in Info.plist of 'Bundle display name':

Change App Icon: First, add the new icon to Images.xcassets. Then, in Xcode, navigate to the app icon settings and select the new icon from the available options.

---

Step 7:

In Podfile make these changes:

    # react-native-config
    pod 'react-native-config', :path => '../node_modules/react-native-config'
    # For extensions without React dependencies
    pod 'react-native-config/Extension', :path => '../node_modules/react-native-config'
    # react-native-config

Also add these:

  target 'development' do
    inherit! :complete
  end
  target 'production' do
    inherit! :complete
  end
//  target 'myapp_mappTests' do
//    inherit! :complete
//    # Pods for testing
//  end
