title: Change UITableViewCell Font in iOS 8 and swift
body: <p>I'm trying to change the font for my uitableviewcells,</p>
  
  <p>I'm trying to use this at the moment with not success:</p>
  
  <pre><code>cell.textLabel.font = [UIFont .preferredFontForTextStyle("Avenir")];
  </code></pre>
  
  <p>Now i've read a lot on this and it seems I should use this instead :</p>
  
  <pre><code>    cell.textLabel.font = [UIFont fontWithName: "Avenir" size:22];
  </code></pre>
  
  <p>Problem is fontWithName does not seem to exist in iOS 8</p>
  
  <p>any ideas??</p>
  
  <p>thanks</p>
