🐛 Bug: Missing x86_64 Simulator Support

[nativecoder1996]

Description

The react_native_stallion native module fails to compile for x86_64 simulators. This causes build errors on Intel-based Macs or CI environments that still expect universal simulator support.

Error Output

Could not find module 'react_native_stallion' for target 'x86_64-apple-ios-simulator';
found: arm64-apple-ios-simulator, at: ...

Steps to Reproduce

1. Install and link react_native_stallion
2. Run the app on an Intel Mac or select an x86_64 simulator (e.g. iPhone 8)
3. Xcode fails to compile with the above error

Expected Behavior

The module should compile for all supported architectures (arm64, x86_64) for iOS simulators.

Workaround (Not Ideal)

In the Podfile, we can avoid this by excluding x86_64 architectures:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings['EXCLUDED_ARCHS[sdk=iphonesimulator*]'] = 'x86_64'
    end
  end
end

But this forces the use of only ARM64 simulators and breaks compatibility with Intel-based developers and some CI setups.

Suggested Fix

Please include both x86_64 and arm64 architectures in the iOS simulator slice of the react_native_stallion.framework. This can be done by:

• Updating the Xcode build settings to include x86_64 as a supported arch for the simulator
• Or distributing the precompiled module with fat binaries (universal slices)

Environment

• macOS: sequoia 15.5
• React Native: 0.80.1
• Xcode: 16.2
• Device: iOS Simulator 16 18.4

@nativecoder1996 thanks for reporting this ! We will try to reproduce this issue and possibly plan a fix for the next patch release 2.3.x.

Fix is very simple. Please do so!
