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

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
