UITableViewCell dynamic custom height based on label text length in Swift

Question

I'm trying to make a dynamic cell with a label using swift to support IOS7 in heightForRowAtIndexPath , but I only find objective-c code, is it possible for someone else to help me rewrite this code to fast?

  // Fetch yourText for this row from your data source.. NSString *yourText = [yourArray objectAtIndex:indexPath.row]; CGSize lableWidth = CGSizeMake(300, CGFLOAT_MAX); // 300 is fixed width of label. You can change this value CGSize requiredSize = [yourText sizeWithFont:[UIFont fontWithName:@"Times New Roman" size:19] constrainedToSize:lableWidth lineBreakMode:NSLineBreakByWordWrapping]; // You can put your desire font // Here, you will have to use this requiredSize and based on that, adjust height of your cell. I have added 10 on total required height of label and it will have 5 pixels of padding on top and bottom. You can change this too. int calculatedHeight = requiredSize.height+10; return (float)calculatedHeight; 

exactly this statement (how to convert it to quick):

 CGSize requiredSize = [yourText sizeWithFont:[UIFont fontWithName:@"Times New Roman" size:19] constrainedToSize:lableWidth lineBreakMode:NSLineBreakByWordWrapping] 

I tried converting it (but it does not work like the original objective-c):

  var requiredSize: CGSize = originalString.sizeWithAttributes([NSFontAttributeName: UIFont.systemFontOfSize(19.0)])

It may be possible to do this without UILabel , but it works just fine.

 let label = UILabel(frame: CGRect(x: 0, y: 0, width: 300, height: 10000)) label.text = someText label.numberOfLines = 100 label.font = UIFont(name: "Times New Roman", size: 19.0) label.sizeToFit() return label.frame.height + 10
