Create directory Fonts and drag-n-drop the files to the directory, and on the pop up make sure to check copy files if needed
Register the custom fonts on Info.plist
Using the custom fonts on storyboards
Using the custom fonts on code

public static func montserratRegular(fontSize: CGFloat) -> UIFont {
        guard let customFont = UIFont(name: "Montserrat-Regular", size: fontSize) else {
            fatalError("""
                Failed to load the "Montserrat-Regular" font.
                Make sure the font file is included in the project and the font name is spelled correctly.
                """
            )
        }
        return customFont
    }
