title: With Xcode 6.2 Update, Find in Workspace Crashes
body: <p>After updating Xcode to 6.2 (6C131e), doing "Find in Workspace" crashes with "UNCAUGHT EXCEPTION (NSInternalInconsistencyException): Could not find class named UIImage". I tried "Clean Build Folder" to no avail. Are there other Xcode caches or indexes that I should try to reset?</p>
