Linker Errors — Undefined Symbols for RNScreens and BottomTabs on iOS (RN 0.76.2 + Xcode 16)

[archan96]

Problem

I'm encountering linker errors on iOS when trying to build with the latest versions of react-native-screens and @react-navigation/bottom-tabs in a React Native 0.76.2 project using Xcode 16.0.

These are the errors:
Undefined symbol: _RNSBottomTabsCls Undefined symbol: _RNSBottomTabsScreenCls Undefined symbol: _RNSScreenStackHostCls Undefined symbol: _RNSSplitViewHostCls Undefined symbol: _RNSSplitViewScreenCls Undefined symbol: _RNSStackScreenCls Linker command failed with exit code 1

What I’ve Tried

• Explicitly added RNScreens to Podfile:

  pod 'RNScreens', :path => '../node_modules/react-native-screens', :modular_headers => true
  
  

Added @react-navigation/bottom-tabs manually

Upgraded to:
"@react-navigation/native": "^7.1.16", "react-native-screens": "^4.13.1"

• Used use_frameworks! :linkage => :static
• Added pre_install block to set RNScreens build type as static library
• Cleaned build folder, deleted DerivedData, reinstalled pods
• Set IPHONEOS_DEPLOYMENT_TARGET = 15.6
• Disabled arm64 for simulator
• Tried on multiple machines – same result

Was this solved somehow, or does the issue persist? If so, please open an issue, preferably with reproduction.

I won't close the discussion yet. Let me know ☝🏻 & I'll transform it into issue.

The issue still persists across most versions of the library, but it doesn’t occur in react-native-screens@^3.31.1.
Since not everyone in the organization is affected, it appears to be intermittent.

That's really interesting. I've never had this kind of issue, which (at a first glance) indicates some misconfiguration on your end or this is something highly specific to the exact version of software that you're using.

In first case: I'd need a proper reproduction project, where I'd be able to observe the issue on end to start debugging. In second case it is recommended to upgrade the RN, especially that RN 0.76 is unsupported since 4.5.0 version of react-native-screens.

Unfortunately I won't be able to help more with such a limited amount of information. It would be useful to see whole linker invocation together with compiler logs, exact environment & lib versions.
