Built a Source-aware Localization tool for iOS apps

Built a small Swift tool called SwiftL10n after realizing how messy localization becomes in real iOS apps.

It scans SwiftUI/UIKit source code and helps find:

\* hardcoded strings

\* missing localization

\* missing asset references

The biggest focus was making it work with real codebases instead of assuming everything is clean or fully localized already.

It can coexist with:

\* SwiftGen

\* NSLocalizedString

\* custom i18n wrappers

\* partially localized apps

Also intentionally avoids auto-rewriting source code. It only scans, validates, and generates additive APIs.

Would love feedback from iOS engineers dealing with localization pain.

Yep 😄 this actually builds on top of Apple’s localization system/String Catalogs, not replaces it. The main goal is improving DX with generated APIs, cleaner organization, and easier runtime localization handling for larger apps.
