Error with `pod install` using Expo 42 & `use_frameworks!`

Summary

Enabling use_frameworks! with Expo 42 in a bare workflow causes pod install to fail because @unimodules/core includes statically linked binaries.

Managed or bare workflow? If you have ios/ or android/ directories in your project, the answer is bare!

Reproducible demo or steps to reproduce from a blank project

Demo project created using the steps below: https://github.com/carsondarling/expo42_use_frameworks_error_demo

Steps to Reproduce

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

# 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, '11.0'

target 'expo42useframeworkserrordemo' do
  use_frameworks!
  use_unimodules!
  config = use_native_modules!

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

  # Uncomment to opt-in to using Flipper
  #
  # if !ENV['CI']
  #   use_flipper!('Flipper' => '0.75.1', 'Flipper-Folly' => '2.5.3', 'Flipper-RSocket' => '1.3.1')
  #   post_install do |installer|
  #     flipper_post_install(installer)
  #   end
  # end
end

1. cd ios && pod install
2. Pod install fails with the following error: [!] The 'Pods-expo42useframeworkserrordemo' target has transitive dependencies that include statically linked binaries: (/Users/cdarling/Workspace/expo42_use_frameworks_error_demo/node_modules/@unimodules/core/ios/UMCore.xcframework)

Hey @carsondarling 👋 Thanks for reporting this issue to us and I apologize this is the case for you 🙇 Looks like it’s related to the prebuilt binary of unimodules core, so the solution might be to compile the package from sources. There are two ways to do this:

1. Add $ExpoUseSources = ['@unimodules/core'] somewhere at the top of your podfile (if it still breaks for another package then you can add it there too).
2. Run EXPO_USE_SOURCE=1 pod install which entirely opts-out from using the prebuilt binaries from .xcframework files

It’s definitely not a long-term solution, but I’d appreciate if you can let me know if that helps, at least for now 🙂

Hey all! #14523 is going to fix these problems, we will keep you informed here 🙂 cc @Kudo
