Usage

Installing Fonts

To install a custom font in your app bundle, follow these steps:

1. Add the font file to your project

Add the font file (typically with a .ttf or .otf extension) to your Xcode project. Make sure the file is included in the target membership.

2. Register the font

In your code, register the font using the provided FontKit.registerFont(withName:) method:

FontKit.registerFont(withName: "CustomFont-Regular") { success, error in
  if success {
    // Font installation successful
  } else {
    print("Font installation failed: \\(error?.localizedDescription)")
  }
}

3. Use the font

After successfully installing a font, you can use it in your app like any other system font. Simply refer to it by name:

let customFont = UIFont(name: "CustomFont-Regular", size: 16.0)

Uninstalling Fonts

To remove an installed font from your app, use the FontKit.unregisterFont(withName:) method:

FontKit.unregisterFont(withName: "CustomFont-Regular") { success, error in
  if success {
    // Font removal successful
  } else {
    print("Font removal failed: \\(error?.localizedDescription)")
  }
}

Browsing and Previewing Fonts

FontKit provides a built-in UI to browse and preview installed fonts. To use it, present an instance of FontKitFontsViewController as part of your user interface:

let fontsViewController = FontKitFontsViewController()
present(fontsViewController, animated: true, completion: nil)
