Localization failed to read a strings file (Xcode 6.3.2)

问题

I can't export for localization, I just get a "Localization failed to read a strings file" error.

The system log says:

2015-06-07 01:41:48,305 Xcode[1914]: [MT] DVTAssertions: Warning in /SourceCache/IDEFrameworks/IDEFrameworks-7718/IDEFoundation/Localization/IDELocalizationWork.m:434

But I have no idea what file "Localizable.strings" is. These steps didn't work:

• Found "Localizable.strings" in Base.lproj and deleted it. It was completely empty.
• Deleted the whole folder specified in the log message.
• Clean and Clean build folder.
• Running genstrings first to generate missing .strings-files. genstrings complained and said my strings weren't literals in the calls to NSLocalizedString. Uhh... they all look like this: private let ALERT_REMINDER_FIRED_TITLE = NSLocalizedString("ALERT_REMINDER_FIRED_TITLE", tableName:"ReminderHandler", comment:"my comment")

I figure that Localizable.strings is supposed to contain someting, like /** no localizable strings **/ or something. The problem with that is that my project doesn't even contain the file, it's being generated as completely empty.

回答1:

Seems that unfinished and commented out calls to NSLocalizedString interfere with export for localization.

回答2:

For me it was like key = "your string"; that worked in swift 3. No quotes for key. Semicolons at the end.

I had the same problem when tried to use NSLocalizedString with own NSBundle specified. Seems Xcode won't work if you use localization macros with different form than NSLocalizedString("Some key", comment: "Some comment"). I have fixed this by just redefining the NSLocalizedString function like that:

public func NSLocalizedString(key: String, tableName: String? = nil, bundle: NSBundle = NSBundle.mainBundle(), value: String = "", comment: String) -> String
{
    return yourBundleHere.localizedStringForKey(key, value: value, table: tableName)
}

Replace yourBundleHere with NSBundle.mainBundle() or what ever you want.

回答4:

Check if there are redundant double quotation marks in your Localizable.strings file, then remove them.

回答5:

The problem for me was that I had completely empty xx.strings files - I'd manually cleared them out.

Add this line at the top of any empty xx.strings files, and the export works again:

/* No Localized Strings */

回答6:

Had the same issue. In my case it was caused by an NSLocalizedString that used a variable passed from the server as the key instead of actual strings. The system still scans commented code so anything short of deleting the lines of code will not work.
