Error building with use_frameworks in Expo 39

🐛 Bug Report

Summary of Issue

Enabling use_frameworks! with Expo 39 causes the build fail in Xcode. This happens using the bare-minimal template, and appears to be an issue with the linking of react-native-screens and react-native-gesture-handler.

Reproducible Demo

Demo project created using the steps below: https://github.com/carsondarling/expo39_use_frameworks_error_demo

Steps to Reproduce

1. expo init --npm --template bare-minimum
2. Update Podfile to enable use_frameworks! and remove Flipper:

# ios/Podfile
require_relative '../node_modules/react-native/scripts/react_native_pods'
require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

platform :ios, '10.0'

target 'expo39useframeworkserrordemo' do
  use_frameworks!
  use_unimodules!
  config = use_native_modules!

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

1. cd ios && pod install
2. Attempting to build in Xcode now fails when linking react-native-screens and react-native-gesture-handler with the errors below:

Expected Behavior vs Actual Behavior

Expected: Able to use use_frameworks! with Expo 39 Actual: Build fails as soon as use_frameworks! is added

It’s entirely possible that I’m missing some key step here, but I’ve been staring at this for a while now and haven’t been able to come up with a solution.

@brentvatne I’ll certainly look into it. Unfortunately I’m pretty much completely swamped right now so the raw hours I’ll have available. to put into it are fairly minimal in the short term.

Thanks again your help!

I am impacted by this issue as well. Thanks in advance,
