Genstrings throttles when using a parameter value in Swift

Question

I have a main Swift Test.swift file containing

 import Foundation import UIKit class Test: NSObject { let a: String let b: String override init() { a = NSLocalizedString("key 1", tableName: nil, bundle: NSBundle.mainBundle(), value: "value 1", comment: "comment 1") b = NSLocalizedString("key 2", comment: "comment 2") } } 

When I run genstrings in this file, I get an unexpected warning

 $ genstrings -u Test.swift Bad entry in file Test.swift (line = 9): Argument is not a literal string. 

and in the generated Localizable.strings file there is no entry for "key 1"

 $ cat Localizable.strings ??/* comment 2 */ "key 2" = "key 2"; 

However, when I make an equivalent in Objective-C using the code below in the Test.m file

 #import <Foundation/Foundation.h> #import <UIKit/UIKit.h> @interface Test: NSObject @property (nonatomic, strong) NSString *a; @property (nonatomic, strong) NSString *b; @end @implementation Test - (id)init { self = [super init]; if (self) { self.a = NSLocalizedStringWithDefaultValue(@"key 1", nil, [NSBundle mainBundle], @"value 1", @"comment 1"); self.b = NSLocalizedString(@"key 2", @"comment 2"); } return self; } @end 

The genstrings command works as expected, and I get an entry for "key 1" .

 $ genstrings -u Test.m $ cat Localizable.strings ??/* comment 1 */ "key 1" = "value 1"; /* comment 2 */ "key 2" = "key 2"; 

What am I doing wrong?

This is a generation error in Xcode 6.4 and Xcode 7 beta, as in https://openradar.appspot.com/22133811 :

In Swift files, genstrings Chokes On NSLocalizedString calls more than two parameters

Summary: when you run genstrings against a Swift file, if there are any calls to NSLocalizedString that use more than the trivial case the parameters "value" and "comment" generate errors ....

Obviously, Apple has stepped back from supporting genres. Use instead:

 xcrun extractLocStrings 

as your team. For example, to create Localizable.strings for your project:

 find ./ -name "*.m" -print0 | xargs -0 xcrun extractLocStrings -o en.lproj 

and for Swift:

 find ./ -name "*.swift" -print0 | xargs -0 xcrun extractLocStrings -o en.lproj 

Note that if you intend to export to a .xliff file, you no longer need to run genstrings as xCode

Editor> Export for Localization

Command

will process your lines "behind the scenes".

Update: Im on xCode 7.3.1 and on my system xtractLocStrings is binary.

 $ file /Applications/Xcode.app//Contents/Developer/usr/bin/extractLocStrings /Applications/Xcode.app//Contents/Developer/usr/bin/extractLocStrings: Mach-O 64-bit executable x86_64 

Here is my test:

 let _ = NSLocalizedString("1st", comment: "1st string") let _ = NSLocalizedString("Second", tableName: "Localized", bundle: NSBundle.mainBundle(), value: "2nd", comment: "2nd string") 

and here are the results:

 Localizable.strings: /* 1st string */ "1st" = "1st"; Localized.strings: /* 2nd string */ "Second" = "2nd";
