EXC_BAD_ACCESS Crash with stubs from a swift class

[JM]

Hi All, I'm having some issues with stubbing a swift class in Objective C..

Most of my code is in objective C, but I introduced a swift class and want to stub a property on an instance. 

For example I have a UITableViewController, for it's numberOfRows, it users "vendors.count", where vendors is a swift class. In my stack trace, I'll see vendors.count be valid up until I get into the swift class and get a BAD_ACCESS

Is this expected given the current state of Cedar/Swift?

I'm not so sure this is expected... 

Could you please provide enough sample code to show the setup of the test subject and the model in question?

I tried to setup a new project and cannot reproduce the way I expected I'd be able to

here is the numberOfRows method

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        guard let searchResult: VendorSearchResult = self.searchResult where searchResult.vendors.count > 0 else {
            return 0
        }
        return searchResult.vendors.count + Int(self.canFetchMore)
    }

It crashes when trying to access the searchResult.vendors.count, searchResult has a stubbed selector, which isn't even related to vendors.count..  but as long as it's stubbed I get this error.

Actually - Simply spying on it makes it crash.. If I don't spy - it's fine.

Also seeing this. If I've spied on a Swift class, it'll throw an EXC_BAD_ACCESS on simple setters like this:

self.property = value

Hello - is the class you're spying on a descendent of NSObject?
