O Linker Error
I have tried to add a testunit target to my project but failed enourmously. My testunit requires libxml2.dylib (actually libxml2.2.dylib) and of course sentestingunit.framework. I add the libxml2.dylib to the FRAMEWORK_SEARCH_PATHS in build settings $(inherited) "$(SYSTEM_APPS_DIR)/Xcode.app/Contents/Developer/Library/Frameworks"
Then I add the sentestingunit.framework in the build phase -> link binary with libraries. I have my app (called vindfyrar) as a target dependencies. Now the the build of my testing target start to scream all the stuff below; Any one got an idea what I have done wrong? i386? Why?
Beleive me on this one, I have done my homework, ie googled and try every option in the build settings that could possible be wrong... No success. XCode 4.6 on Lion 10.7.5
Kind regards, Jan Gifvars

You're linking against the iPhoneOS SDKs (where all the binaries are built for architecture arm) but you're building an iPhone Simulator program (i386). Your project is linking against the wrong SDK.
I have solved the problem by adding these setting and values.
For Test Host it's $(BUNDLE_LOADER) For Bundle Loader it's $(BUILT_PRODUCTS_DIR)/ApplicationName.app/ApplicationProductName
If you want more details log in to apple.developer and search for "Test case give Apple Mach-O Linker Error"
Thanks everyone for your time!
