Blog post / Dynamic Type - Extending Optional when the wrapped value is of type UIFont, so we can return the custom font object or precondition failure
extension Optional where Wrapped == UIFont {
var unwrapped: Wrapped {
switch self {
case .some(let font): return font
case .none:
preconditionFailure("""
Could not load font from available fonts:
\(UIFont.familyNames.joined(separator: ", "))

Blog post / Dynamic Type - Defines scalable fonts behaviour and extends itself when conditionally conforms to raw representable of raw type string (what we use in our custom fonts)

if let maxSize = maxSize {
return fontMetrics.scaledFont(for: self, maximumPointSize: maxSize)
}
