XCode 16.1 - React Native app will not compile

So I have a pretty old React Native app that I maintain. Think 6-7 years old and still using libraries from that time.

One of the libraries I use is:

react-native-job-queue

and I cannot seem to get past this error no matter what switches I give the compiler:

Command SwiftVerifyEmittedModuleInterface failed with a nonzero exit code

I get this for another React Native library as well. No code has changed, nothing in the project has changed. It was just the XCode / iOS / MacOS upgrade that broke this.

I've tried the following OTHER SWIFT FLAGS:

-disable-interface-file-verification -no-verify-emitter-module-interface

and others I'm probably forgetting. My .xcconfig has these:

OTHER_SWIFT_FLAGS = $(inherited) -Xfrontend -disable-implicit-swift-modules -no-verify-emitter-module-interface SWIFT_VERIFY_EMITTED_MODULE_INTERFACE = NO SWIFT_EMIT_MODULE_INTERFACE_VERIFY=NO

None of these actually stop the verifier so the compile fails every time. Any help is appreciated!!

Thank you for the post. I recommend reaching out to the React Native developers on their support channels for assistance. While some members of this forum may have experience, it appears that they may be using a newer version of the framework, as you mentioned that it could be around 6-7 years old maybe there is a new one available?

The error message “Command SwiftVerifyEmittedModuleInterface failed with a nonzero exit code” should provide more detailed information about the preceding errors. Please provide this information to the support channels of React Native.
