I want to apply "System semibold 13.0" (this is the name of the font in storyboard) onto the header for a tableview cell group. To do that I'm using:
let header = view as! UITableViewHeaderFooterView
header.textLabel?.font = UIFont(name: "Futura", size: 38)!
header.textLabel?.textColor = UIColor.lightGrayColor()
but idk what to put for the name string. I've tried entering "System Semibold" and "Semibold" but both result in an unwrapped optional crash. What do I have to put in the string to make it use "System semibold 13.0"?
