In my Cocoa application written in Swift (Xcode 6 Beta 6 on OS X Mavericks) I would like to use a bundle resource. Is does not use any external libraries but only the WebKit.framework. I encountered an odd linker problem with the code I wrote and could reduce it to the second line in this snippet:
var bundle = NSBundle.mainBundle()
// Leads to linker error!
var path = bundle.pathForResource(resource, ofType: "js")
If I comment out the pathForResource line it compiles and runs fine. Otherwise it causes the build to fail. That is the output in where Xcode shows the error:

I read about architecture problems with frameworks but they all were related to the framework as a whole. Not the use of single method. This leaves me puzzled. Even more irritating is that NSBundle.pathForResourceis a class method in the foundation framework. Is there kind of a cache for built objects which I eventually need to purge?
I feel cursed. Whenever I try to do something with Xcode I encounter the strangest problems.
