In code , I can define a UILabel has a dynamic font like this, and I change this body TextStyle font from default size to 30.

label.font = UIFontMetrics(forTextStyle: .body).scaledFont(for: UIFont.systemFont(ofSize: 30))

But in Xib , I can only use the default body TextStyle .
Is there any way to change body TextStyle ‘s default configuration in xib?
