Would anybody happen to have a tiny bit of compassion for very new and inexperienced coder and have some insights about how to fix these errors?
I’m trying to build a React Native app for the first time using Xcode (v16.2 on macOS Sonoma, Apple Silicon M1). After running npx pod-install and opening the .xcworkspace file in Xcode, I encounter multiple “Could not build module ____” errors when I attempt to build the iOS target.
⸻ Desired Behavior:
I expect the Xcode project to build successfully so I can run the app in the iOS Simulator.
⸻ What I’ve Done: • Running on macOS Sonoma, Apple M1 MacBook Air • Using Xcode 16.2 (Build 16C5032a) • CocoaPods installed (pod --version: 1.14.3) • React Native 0.73.x (modular Firebase setup) • Cleared DerivedData • Ran pod deintegrate, pod install, and npx pod-install • Reinstalled Xcode + CLI tools • Verified a new empty SwiftUI project builds fine • Added use_frameworks! :linkage => :static for Firebase compatibility
⸻ Podfile
platform :ios, '16.0' use_modular_headers!
require_relative '../node_modules/react-native/scripts/react_native_pods' require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
target 'Sfir2' do config = use_native_modules!
Use static frameworks to avoid conflicts with Swift linking
use_frameworks! :linkage => :static $RNFirebaseAsStaticFramework = true
use_react_native!( :path => config[:reactNativePath], :hermes_enabled => true )

These appear to affect multiple standard system modules and some Firebase modules. This prevents compilation entirely.
What could be causing these “Could not build module” errors in system modules, and how can I resolve them?
Is there a known issue with React Native + Firebase modular SDK on Xcode 16.2 or M1 Macs?
