Answer 1

comment out flipper command block if you are not using it.

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '10.0'

target 'studypal' do
  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])

  target 'studypalTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  # use_flipper!
  # post_install do |installer|
  #   flipper_post_install(installer)
  # end
end

target 'studypal-tvOS' do
  # Pods for RnDiffApp-tvOS

  target 'studypal-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end
end

then try running pod install again

cd ios

pod install

this works for me everytime

Seems like you add xcodeproj property and that is causing the crash. Just rid that line.

require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '10.0'

target 'studypal' do
  config = use_native_modules!

  use_react_native!(:path => config["reactNativePath"])

  target 'studypalTests' do
    inherit! :complete
    # Pods for testing
  end

  # Enables Flipper.
  #
  # Note that if you have use_frameworks! enabled, Flipper will not work and
  # you should disable these next few lines.
  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
  end
end

target 'studypal-tvOS' do
  # Pods for RnDiffApp-tvOS

  target 'studypal-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end
end
