title: Converting sizeWithFont method to Swift
body: <p>I'm going over old obj-c tutorial and having hard time understanding obj-c code. And they are apparantely deprecated.
  I've looked into other stackoverflow questions but I still could not figure out since none of them were not in Swift.</p>
  
  <pre><code>   CGSize textSize = [text sizeWithFont:textFont constrainedToSize:CGSizeMake(printableFrame.size.width, CGFLOAT_MAX) lineBreakMode:UILineBreakModeWordWrap];
     CGRect textFrame = CGRectMake(printableFrame.origin.x, currentY, textSize.width, textSize.height);
  </code></pre>
  
  <p>How can I convert above code to Swift?</p>
