I am creating a custom table cell view for my table view. After I connect an image view of custom cell (in storyboard) to my code in swift, I get the following error.

Thank you.
I add an exception breakpoint in my project.
This is the line where it breaks.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell { let cell = self.tableView.dequeueReusableCellWithIdentifier(kCellIdentifier) as ItemTableViewCell <--------------- But I don't use 'image' in my code.

Once you run this line of code you will instantly get an error message in the console area, which look s like this (unrecognized selector sent to instance). Since the selector is another name for the method, the error is basically saying that it doesn't recognize the function that you're trying to call on this object.

Since the selector is another name for the method, the error is basically saying that it doesn’t recognize the function that you’re trying to call on this object. The error also gives us the information that we are trying to call the set image method of an object that is a UIButton.
You can see there are two functions that have been connected to the Sent Events —> Touch Up Inside event. You should click the close button on the unused function left side to remove the connection.
Try setting a symbolic breakpoint on -[NSObject(NSObject) doesNotRecognizeSelector:]. Just click [+] in the bottom left corner of the Breakpoint Navigator to add a breakpoint. Then click 'Add Symbolic Breakpoint'. Reproducing your crash now should give you a better idea where in your code the issue occurs.
