Use of bitwise '|' with boolean operands | Xcode 14.3 fails builds using react-native Yoga
Use of bitwise '|' with boolean operands | Xcode 14.3 fails builds using react-native Yoga
Matthew C.
—The Problem
When creating the build for a React Native project in Xcode IDE version 14.3 or above, you get the following error:
Use of bitwise '|' with boolean operands
This is an npm dependency error. It occurs in the Yoga.cpp file of the React Native dependency and layout engine, Yoga. This error only occurs when using React Native version 0.68 or lower or when running unpatched versions of React version 0.6, 0.70, or 0.71.
The Solution
Upgrade to React Native version 0.72+ or to one of the patch releases with an added fix for the issue:
- Version 0.71.6
- Version 0.70.8
- Version 0.69.9
If upgrading is not possible or if you need a quick fix, you can change the bitwise operator | to the boolean operator || yourself. You can use a library such as patch-package to make and keep fixes to the React Native npm dependency.
Another option is to downgrade your Xcode to version 14.2.1 or lower, as older versions do not have the version checks that cause the error.
Note
The C++ Yoga code changed the bitwise operator | to the boolean operator || to guarantee a return of true or false only.
The root cause of the error is that Xcode version 14.3 introduced some version checks, including an iOS version check. React Native uses CocoaPods to manage library dependencies for Xcode projects. The library dependency React-Codegen supports iOS 11, which does not build with Xcode 14.3 as described in this React Native PR.
