Fixing 'Command PhaseScriptExecution failed with a nonzero exit code' in Xcode/Swift

If you have encountered the error message 'Command PhaseScriptExecution failed with a nonzero exit code' while working in Xcode, you're not alone. This error typically stems from issues in your build scripts or configurations. Here’s how you can troubleshoot and resolve this issue.

Common Causes and Solutions:

  • Check your build scripts: Often, the failed script may have incorrect paths or commands. Make sure that all references in your scripts point to the correct locations.
  • Review permissions: If your script interacts with files, ensure that it has the necessary permissions to execute without errors.
  • Cleansing the build: Sometimes, residual files can cause issues. Go to the Product menu in Xcode and select 'Clean Build Folder' (hold the Option key and select 'Clean Build Folder').
  • Check for missing dependencies: Ensure all required pods, frameworks, and dependencies are correctly installed and configured within your project.
  • Verbose output: To identify the exact cause of the failure, you may modify your script to provide verbose output. This can help pinpoint the issue.

Example Troubleshooting Script:

#!/bin/bash set -e echo "Starting PhaseScriptExecution..." # Example command if [ ! -d "$PROJECT_DIR/Dependencies" ]; then echo "Dependencies directory not found!" exit 1 fi # Continue with further commands echo "Dependencies found. Continuing..."
