# Treating Warnings As Errors In Swift Packages

**[Use Your Loaf](https://daily.dev/sources/useyourloaf)** · 2 min read · 0 upvotes · 0 comments

## Summary

Swift 6.2 introduces fine-grained compiler warning controls for Swift Packages, allowing developers to treat specific diagnostic groups as errors or warnings. Previously available only in Xcode build settings, these controls can now be configured directly in Package.swift files using new swiftSettings like treatAllWarnings(as: .error) and treatWarning("group", as: .warning). The settings only apply when building packages directly, not as remote dependencies.
