Description Mark Rowe (bdash) 2015-02-11 14:16:57 PST
extract-localizable-strings.pl is typically run unconditionally during the build since it's difficult to get the dependencies right. The current behavior results in the output file always being updated, which results in Xcode always needing to copy the file into the framework. This has a flow-on effect of causing any dependent targets to be relinked against the framework. There are two ways to address this:
1) Only run extract-localizable-strings.pl if any of the files it considers have changed. This is difficult to arrange for with Xcode's build system, and would be cumbersome even with make.
2) Only update the target file if the new localizable strings are different from the existing localizable strings.

This patch will take option 2.
