3. Styling

Well, just call style on a UIView subclass :

In-line for small or unique styles

detail.style { l in
  l.numberOfLines = 0
  l.textAlignment = .Center
  l.textColor = .blueColor()
  l.text = NSLocalizedString("NeedPetMessage", comment: "")
}

Or in a separate to make them reusable

// My style method, kinda like CSS
func detailStyle(l:UILabel) {
  l.numberOfLines = 0
  l.textAlignment = .Center
  l.textColor = .blueColor()
  l.text = NSLocalizedString("NeedPetMessage", comment: "")
}

// Later
{
  // Set my style
  detail.style(detailStyle)
}

This is the preferred way because the styles become reusable and composable: you can chain them! You can even create a Style File grouping high level functions for common styles. Usage then becomes very similar to CSS!
