Swift Configuration 1.0 unifies config sources

Type-safe, provider-agnostic configuration API eliminates scattered parsing logic by enforcing a single read pattern across multiple sources with clear precedence.

Summary

Removes coupling between application code and configuration sources, letting libraries accept config without dictating where it comes from. Enables hot-reload, secret redaction, and access logging without refactoring existing read calls.

Why it matters

Implementation verdict

Replaces ad-hoc env/file/arg parsing scattered across your codebase. Requires adding swift-configuration package and refactoring config access to use ConfigReader. Production-ready now—40+ PRs merged since October, API stable at 1.0. Worth adopting immediately for server apps and CLI tools.

Sources

1.With the release of Swift Configuration 1.0, the library is production-ready to serve as a common API for reading configuration across the Swift ecosystem.
2.Since the initial release announcement in October 2025 over 40 pull requests have been merged, and its API stability provides a foundation to unlock community integrations.
3.This separation unlocks something powerful: libraries can now accept configuration without dictating the source, making them genuinely composable across different deployment environments.
4.Providers are checked in the order you specify: earlier providers override later ones, followed by your fallback defaults.
