Answer 1

The error is because of mix matched version of react native and flipper.

for react-native 63+ it should be following

use_flipper!({ 'Flipper' => '0.58.0' }) then run pod install

More more clarity go through this documentation for manual setup : https://fbflipper.com/docs/getting-started/react-native-ios/
