React has been deprecated - React Native - react-native

Question

I am creating an app using React Native and am trying to install cocoa pods for iOS but when I enter pod install into the terminal I get the following warning.
Then when I try to run my app in an iOS emulator it crashes and won't run.
Here is the Xcode error.
I am running react native 0.63.2.
Here is my pod file
# Uncomment the next line to define a global platform for your project
platform :ios, '11.0'
require_relative '../node_modules/react-native/scripts/react_native_pods'
target 'Example' do
# Comment the next line if you don't want to use dynamic frameworks
#use_frameworks!
# Pods for Example
# pod 'React', :path => '../node_modules/react-native'
pod 'RNSound', :path => '../node_modules/react-native-sound'
pod 'RNCAsyncStorage', :path => '../node_modules/#react-native-community/async-storage'

# Pods for testing
end

end

end

The issue is that you don't install pod for the correctly target.
This is strange if this is a new RN project because it should take the correct target.
In you recently image added seems like you have another target called AntrimElimChurch so if you want to install pod for that target you should change it in PodFile as well
am running react native 0.63.2.
Here is my pod file
# Uncomment the next line to define a global platform for your project
platform :ios, '11.0'
require_relative '../node_modules/react-native/scripts/react_native_pods'
target 'AntrimElimChurch' do
# Comment the next line if you don't want to use dynamic frameworks
#use_frameworks!
# Pods for Example
# pod 'React', :path => '../node_modules/react-native'
pod 'RNSound', :path => '../node_modules/react-native-sound'
pod 'RNCAsyncStorage', :path => '../node_modules/#react-native-community/async-storage'
pod 'RNCMaskedView', :path => '../node_modules/#react-native-community/masked-view'
pod 'RNCPushNotificationIOS', :path => '../node_modules/#react-native-community/push-notification-ios'
pod 'react-native-slider', :path => '../node_modules/#react-native-community/slider'
pod 'RNFBApp', :path => '../node_modules/#react-native-firebase/app'
pod 'RNFBAuth', :path => '../node_modules/#react-native-firebase/auth'
pod 'RNFBMessaging', :path => '../node_modules/#react-native-firebase/messaging'
pod 'RNFirebase', :path => '../node_modules/react-native-firebase/ios'
pod 'RNGestureHandler', :path => '../node_modules/react-native-gesture-handler'
pod 'RNReanimated', :path => '../node_modules/react-native-reanimated'
pod 'react-native-safe-area-context', :path => '../node_modules/react-native-safe-area-context'
pod 'RNScreens', :path => '../node_modules/react-native-screens'
pod 'RNVectorIcons', :path => '../node_modules/react-native-vector-icons'
target 'Example-tvOSTests' do
inherit! :search_paths
# Pods for testing
pod 'react-native-notifications', :path => '../node_modules/react-native-notifications'
end
target 'ExampleTests' do
inherit! :search_paths
# Pods for testing
end
end
target 'Example-tvOS' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# Pods for Example-tvOS
end
After this change run again pod install and it should build
