Swift standard libraries copy phase ignores "Other Code-Signing Flags"

When Xcode copies the standard Swift libraries into an app bundle, it signs the libraries with the pertinent code signing identity, typically either a Mac App Store or a Developer ID identity.

However, it neglects to apply the "Other Code-Signing Flags" options defined in the project or target by the OTHER_CODE_SIGN_FLAGS build setting.

This is problematic because some projects may have good reason to impose specific code signing flags on all signed libraries that are bundled with an app.

A practical example of a workflow that this breaks is for Developer ID signed apps that are built with code signing flags that specify "--timestamp=none" to disable the timestamp server dependency. I define this option specifically for Debug builds so that I can have a faster build and so that I can build and run my projects even when offline:


Since the Swift libraries phase ignores the OTHER_CODE_SIGN_FLAGS, there is apparently no way to build a Developer-ID signed Swift app unless you are both online and the timestamp server is responding reliably.

Xcode 6.4 or 7.x
