@IBOutlet and @IBAction refers to wrong project, how to get rid of those references?
<p>I have copied and pasted some source code from one <strong>old</strong> xcode-project to another <strong>new</strong> project.</p>

<p>Included in the copied code where some @IBOutlets and @IBActions. My intention was to later on hook them up to the storyboard in the new project. <em>However, xcode somehow managed to copy the references to the old project's storyboard</em>.  <strong>How can I get rid of those references?</strong> </p>

<p><strong>Update</strong>: After having added a connection from my storyboard to the buyButton, xcode indicates that the buyButton is connected to two different storyboards.</p>
