Xcode vs VS Code Comparison

// Xcode - Debug mode with Launch Argument
// Scheme > Run > Arguments Passed On Launch
// -com.apple.CoreData.SQLDebug 1
// -UIPreferredContentSizeCategoryName UICTContentSizeCategoryAccessibilityXL

// Xcode custom build configuration
// Environment separation via xcconfig file
// Configuration.xcconfig:
// APP_NAME = MyApp Debug
// API_BASE_URL = https://staging-api.example.com
// BUNDLE_ID = com.mycompany.myapp.debug

// Usage in Info.plist:
// $(API_BASE_URL) → auto-injected

// Using Instruments (command line)
// xctrace record --template 'Time Profiler' \\
//   --attach <pid> --output trace.trace

// Xcode Cloud CI/CD (ci_scripts/ci_post_clone.sh)
#!/bin/bash
set -e

# Cache SPM dependencies
echo "Loading SPM dependencies..."
xcodebuild -resolvePackageDependencies \\
    -scheme MyApp \\
    -clonedSourcePackagesDirPath SourcePackages

# Environment variable injection
echo "MY_VAR=$CI_SECRET_VAR" >> .env.local

echo "Post-clone completed"

// Running tests on Simulator (command line)
// xcodebuild test \\
//   -project MyApp.xcodeproj \\
//   -scheme MyApp \\
//   -destination 'platform=iOS Simulator,name=iPhone 16 Pro' \\
//   -resultBundlePath TestResults.xcresult

// VS Code - Basic usage with Swift extension
// .vscode/settings.json
