title: Tab Bar Item Stopped Changing ViewController
body: <p>My TabBarController was working fine but stopped working after adding custom Images and removing titles. I put custom images and also added a Navigation Bar behind the Tab Bar Controller on the stack. Before it was navigating to VCs when I click on the Tab Bar items but now it just doesn't do anything. The selected after the viewLoads is also highlighted.</p>
  
  <p>The relationships also seems fine on TabBarController (<code>relationship 'viewcontrollers' to item'</code>)</p>
  
  <p>What may be the reason?</p>
