title: How to get the index of the row (cell) I clicked on in TableViewController
body: <p>I am beginner in Swift and probably this is fundamental stuff but I need to get the index of the row (cell) I clicked on in the tableview. </p>
  
  <p>I have TableViewController with predefined methods, but I wasn't able to find what I am looking for.</p>
  
  <p>Rows (cells) are string from the string array. </p>
