Summary

Four locales: en, en-CA, fr-CA, fr. ~2,000 strings per locale in the main bundle. Most code uses NSLocalizedString but some hardcoded literal text remains. No pseudo-localization in debug schemes.

Localization toolchain recommendations

SwiftGen — generate L10n enum from Localizable.strings; compile-time error on missing keys.
String Catalogs (.xcstrings) — Xcode 15+ format; replaces .strings + .stringsdict; built-in plural / variant support.
Pseudo-localization scheme — Xcode "Show non-localized strings" launch arg + a custom pseudo-locale build configuration.
Lokalise / Phrase — translation memory + machine-translation pipeline.

Plurals / dates / currency

Verify NumberFormatter uses Locale.current not Locale(identifier: "en_US"). Use .stringsdict (or .xcstrings) for plurals — NSLocalizedString alone doesn't handle "1 item" vs "2 items" correctly across languages.

Findings

PASS

4 locale variants with snapshot coverage

Locale-specific snapshot test plans (EN_CA, EN_US, FR_CA) lock visual layout per language.

MEDIUM

Hardcoded text in some screens

Some label.text = "..." literals bypass NSLocalizedString.

Recommendation: SwiftLint custom rule banning string literals in .text setter; SwiftGen for compile-time string safety.

MEDIUM

No pseudo-localization scheme

Pseudo-locales (en-XA, ar-XB) catch truncation, encoding, and RTL bugs early.

Recommendation: Add a Pseudo build configuration that uses -AppleLocale/-NSShowNonLocalizedStrings launch arguments; run snapshot tests against pseudo-locale.

LOW

Number / date formatting

Confirm NumberFormatter + DateFormatter use the user's locale, not Locale(identifier: "en_US").

Recommendation: Audit formatter creation; default to Locale.current for user-facing.
