DDHidLib and Release vs Debug builds

[getaaron]

I am trying to understand why CI is not working. It has something to do with release vs debug builds

This command succeeds:

xcodebuild -derivedDataPath ./build -workspace Boxer.xcworkspace -scheme "Boxer CI" -configuration "Debug"

However, CI should use the Release configuration. When I use that instead...

xcodebuild -derivedDataPath ./build -workspace Boxer.xcworkspace -scheme "Boxer CI" -configuration "Release"

...I get this failure:

** BUILD FAILED **
The following build commands failed:

I tried to see how the run configurations were different. The only thing I noticed were the BOXER_DEBUG and USE_PRIVATE_APIS preprocessor macros, but the build still failed when I tried adding them to the release build.

Workaround

I can workaround this issue by manually editing ./Vendor/DDHidLib/DDHidLib.xcodeproj/project.pbxproj:

diff --git a/DDHidLib.xcodeproj/project.pbxproj b/DDHidLib.xcodeproj/project.pbxproj

                        name = Release;

Then it will make a release build successfully. But ideally should not need to edit vendor dependencies to get a release build.

Do you know a better approach?

Do you know why 10.9 is fine on debug builds but not on release builds?
