  name   number
  Bob      2
  Helena   5
  Helga    1
  Matilda  0</p></li>
  <li><p>I connect my UITableViewController with DB across CoreData and it's working (i see all DB in my simulator of iphone)</p></li>
  <li><p>I want find with swift in my DB cells of column "number" with value, for example, "1" and "2" and show proper cell from column "name" and as result I want to see:
  Bob    2
  Helga  1</p></li>
