RestKit and XCode4 Error

I'm trying to use RestKit in an XCode4 proje开发者_如何学运维ct, but it's giving me this warning:

ld: warning: directory not found for option '-L/Users/kagi/Coding/iOS/Projects/testProject/RestKit/Build/Debug-iphonesimulator'

I'm not seeing anything in my build settings that points to that directory...

Any insight is always appreciated.

I had the same problem. Then I looked at the RKTwitterCoreData example application which is supplied with RestKit.

In its build settings it doesn't set a value for the "Library Search Paths" (contrary to the RestKit instructions on github). I removed this setting from my project and it now works.
