Open Radar

 
Area:
Xcode

Summary:
In case a line accidentally ends in a double semicolon `;;´ in Localizable.strings, this breaks localization in the app. In Xcode, however, this error is not reported.
In contrast to other kinds of syntax errors, no warning, error or other kind of hint is displayed - neither inline (while editing), nor at compile time.
If an error like this happens, then the app won't be properly localized - instead, all localizations following the line ending with `;;´ will be ignored in the language affected.

Steps to Reproduce:
A sample project can be found here: https://github.com/lla01/radar-double-semicolon-in-localizable-strings

1. Open the project
2. In the settings for Scheme/Edit Scheme/Options select 'Application Language: English', 'Application Region: USA'
3. Run in simulator
==> Observe that texts are displayed properly localized

4. Now change language and region to German / Germany
5. Re-build and run in simulator
==> Observe that the second string is not properly localized.

Expected Results:
Xcode should display a warning, a compile time error, or any other hint that the Localized.strings file for German as syntax issues

Observed Results:
No hint displayed

Version:
Xcode Version 8.3.3 (8E3004b)

iOS: n/a (not relevant)

Notes:
Note, that in the Localized.strings for German the first line ends in a double semicolon `;;´

Configuration:
Always happens when there is a line ending in a double semicolon `;;´ in Localized.strings
