react-native-nitro-modules@npm:0.31.10 [0f065] couldn't be built successfully (exit code 1)

[tensfeld]

How were you trying to build the app?

Hi, I'm facing the error "react-native-nitro-modules@npm:0.31.10 [0f065] couldn't be built successfully (exit code 1" when trying to add react-native-nitro-modules to my project.

This can be reproduced this way (react-native-nitro-modules 0.31.10, node 20, yarn 4.12.0, RN 0.82.1)

npx @react-native-community/cli@latest init testProject
yarn set version stable 
yarn install
yarn add react-native-nitro-modules

Log:

I feel I'm missing something...

Can you build the Nitro Modules Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

Additional information

• I am using Expo
• I am using nitrogen
• I have read and followed the Troubleshooting Guide.
• I created a reproduction PR to reproduce this issue here in the nitro repo. (See Contributing for more information)
• I searched for similar issues in this repository and found none.

Hm is your machine running the postinstall script of nitro modules?
Maybe I should remove that and move it into the monorepo's root postinstall..

nitro/packages/react-native-nitro-modules/package.json

Line 62 in e79c057

"postinstall": "bun build || exit 0;",

I'm not sure. Let me give you more context. My plan is to use the component react-native-iap, and as per installation instructions, I should add react-native-nitro-modules to my project (see https://github.com/hyochan/react-native-iap#:~:text=Starting%20from%20version%2014.0.0%2C%20this%20library%20uses%20Nitro%20Modules%20for%20high%2Dperformance%20native%20bridge%20implementation.%20You%20must%20install%20react%2Dnative%2Dnitro%2Dmodules%20alongside%20react%2Dnative%2Diap.)

Thanks for your help.

@mrousavy I guess the issue should be there. Just not to open a new issue I'm posting it here. What the claude code want you to know:

Description

NitroModules fails to build on iOS with the following error:

error: compiling for iOS 15.1, but module 'CxxStdlib' has a minimum deployment target of iOS 16.0

Root Cause

The NitroModules.podspec uses min_ios_version_supported from React Native (line 17):

s.platforms = {
  :ios => min_ios_version_supported,  # This resolves to 15.1 in RN 0.81.5
  ...
}

However, NitroModules enables Swift/C++ interop via:

"SWIFT_OBJC_INTEROP_MODE" => "objcxx"

This requires the CxxStdlib module, which is only available on iOS 16.0+.

Environment

• react-native: 0.81.5
• react-native-nitro-modules: 0.31.10
• react-native-mmkv: 4.1.0
• Xcode: 16.x
• macOS: Sonoma

Reproduction

1. Create an Expo project with New Architecture enabled
2. Install react-native-mmkv (which depends on react-native-nitro-modules)
3. Run npx expo run:ios
4. Build fails with CxxStdlib deployment target error

Current Workaround

Add a post_install hook in Podfile:

installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
    config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '16.0'
  end
end

Suggested Fix

Update NitroModules.podspec to require iOS 16.0 minimum:

s.platforms = {
  :ios => '16.0',  # Required for CxxStdlib (Swift/C++ interop)
  :visionos => 1.0,
  :macos => 10.13,
  :tvos => 13.4,
}

I'm not sure

well, did you try changing it? in your node_modules/react-native-nitro-modules/package.json

Tried it now; updated package.json, postinstall to be "exit 0", error is gone.

Still yarn is not able to add your branch fix correctly (maybe due to monorepo), so for now I'm using a patch-package file for those who are facing similar issue:
