@blumendorf You are absolutely right. I am using multiple targets and adapting configuration worked. Thank you ! 😊

In my Podfile, my targets:

project 'gotobridge',
  'Debug-dev' => :debug,
  'Release-dev' => :release,
  'Debug' => :debug,
  'Release' => :release

And so, my flipper pods :configuration:

def add_flipper_pods!
  version = '~> 0.35.0'
  pod 'FlipperKit', version, :configuration => ['Debug-dev', 'Release-dev']
  pod 'FlipperKit/FlipperKitLayoutPlugin', version, :configuration => ['Debug-dev', 'Release-dev']
  pod 'FlipperKit/SKIOSNetworkPlugin', version, :configuration => ['Debug-dev', 'Release-dev']
  pod 'FlipperKit/FlipperKitUserDefaultsPlugin', version, :configuration => ['Debug-dev', 'Release-dev']
  pod 'FlipperKit/FlipperKitReactPlugin', version, :configuration => ['Debug-dev', 'Release-dev']
end

Also, for the record, after I built my app, it crashed on launch with Thread 1: signal SIGABRT Searching a bit deeper, I found this message: This copy of libswiftCore.dylib requires an OS version prior to 12.2.0. I added a File.swift in my projects, and it was ok. But if I removed the file again, it crashed again. So, in xCode, I went to BuildSettings -> Linking -> runpath search path , and manually changed each build line to:

/usr/lib/swift
$(inherited)

And now it builds and starts fine, without the .swift file

For those using multiple schemes and on 0.63, you can make the following change in your Podfile:

From

use_flipper!

To

use_flipper!(configurations: ['Debug', 'Local.Debug', 'Staging.Debug'])

The flipper pods were made configurable in https://github.com/facebook/react-native/pull/29074
