To revert the User Search Header Paths and Header Search Paths build settings to their defaults set by CocoaPods - select the entry in the Build Settings panel, and hit delete. If one of the folders is a large folder, Xcode will attempt to recursively search the entire directory and throw above error at some point.

Verify that this particular config is not overwritten, and that none of the folders configured are too large. For Pods, CocoaPods uses a default array of specific folders to look in.

In the project's build settings, User Search Header Paths and Header Search Paths are two configs that specify where Xcode should look for #import header files specified in the code. Argument list too long: recursive header expansion failed There is a CocoaPods plugin called cocoapods-fix-react-native which handles any potential post-fixing of the source code due to differences when using a dependency manager. React Native does not compile when being used as a CocoaPod xcworkspace file henceforth to be able to use these installed dependencies. CocoaPods will instruct you to use the generated. Next, make sure you have run pod install and that a Pods/ directory has been created in your project with React installed.
