Fixed: Error “PhaseScriptExecution failed with a nonzero exit code”
What is the error “PhaseScriptExecution failed with a nonzero exit code”?
As an iOS app developer you may encounter a build-time error “PhaseScriptExecution failed with a nonzero exit code.” But what does it actually mean?
This error occurs when a build script fails to run successfully. In Xcode, various phases of the build process rely on scripts — such as those for copying resources, managing dependencies, or executing pre/post-build actions. When one of these scripts encounters an issue and does not complete properly, it returns a "nonzero exit code," indicating that it failed.
To resolve this, review the build logs to identify the specific script that caused the failure. The most common causes include missing or outdated dependencies (e.g., CocoaPods) and stale or corrupt intermediate build files.
Where does this error come from?
This error typically arises from dependency issues within the project, such as missing dependencies, syntax errors, or outdated and incompatible pods.
So, with that in mind, how exactly can you fix this error? Let’s dive into the steps needed to resolve it.
