Read Adding a Custom Font to Your App

The name of the font isn’t always obvious, and rarely matches the font file name. A quick way to find the font name is to get the list of fonts available to your app, which you can do with the following code:

for family in UIFont.familyNames.sorted() {
    let names = UIFont.fontNames(forFamilyName: family)
    print("Family: \(family) Font names: \(names)")
}
