Although you can't specify both a custom font and a preferred text style via Storyboard, it's not difficult to programmatically specify a dynamic type size for your custom font:

Swift:

let pointSize  = UIFontDescriptor.preferredFontDescriptorWithTextStyle(UIFont‌​TextStyleTitle1).poi‌​ntSize
let customFont = UIFont(name: "Chalkboard SE", size: pointSize)

When you receive a UIContentSizeCategoryDidChangeNotification, use the same code to update your label's font.

Obj C:

 CGFloat pointSize = [[UIFontDescriptor preferredFontDescriptorWithTextStyle:UIFontTextStyleHeadline] pointSize];
 [titleLabel setFont:[UIFont fontWithName:@"Marker Felt" size:pointSize]];
