When to use it

When you need to generate Swift 4 code.

Customization

You can customize some elements of this template by overriding the following parameters when invoking swiftgen. See the dedicated documentation.

Parameter Name	Default Value	Description
`bundle`	`BundleToken.bundle`	Allows you to set from which bundle font files are loaded from. By default, it'll point to the same bundle as where the generated code is. Note: ignored if `lookupFunction` parameter is set.
`enumName`	`FontFamily`	Allows you to change the name of the generated `enum` containing all font families.
`fontTypeName`	`FontConvertible`	Allows you to change the name of the struct type representing a font.
`lookupFunction`	N/A¹	Allows you to set your own custom lookup function. The function needs to have as signature: `(name: String, family: String, path: String) -> URL?`. The parameters of your function can have any name (or even no external name), but if it has named parameters, you must provide the complete function signature, including those named parameters – e.g. `myFontFinder(name:family:path:)`. Note: if you define this parameter, the `bundle` parameter will be ignored.
`preservePath`	N/A	Setting this parameter will disable the basename filter applied to all font paths. Use this if you added your font folder as a "folder reference" in your Xcode project, making that folder hierarchy preserved once copied in the build app bundle. The path will be relative to the folder you provided to SwiftGen.
`publicAccess`	N/A	If set, the generated constants will be marked as `public`. Otherwise, they'll be declared `internal`.
`fontAliasName`	`Font`	Deprecated Allows you to change the name of the `typealias` representing a font. Useful when working with SwiftUI, which defines it's own `Font` type.

If you don't provide a lookupFunction, we will use url(forResource:withExtension:) on the bundle parameter instead.

Generated Code

Extract:

swift

internal enum FontFamily {
  internal enum SFNSDisplay {
    internal static let black = FontConvertible(name: ".SFNSDisplay-Black", family: ".SF NS Display", path: "SFNSDisplay-Black.otf")
    internal static let bold = FontConvertible(name: ".SFNSDisplay-Bold", family: ".SF NS Display", path: "SFNSDisplay-Bold.otf")
    internal static let heavy = FontConvertible(name: ".SFNSDisplay-Heavy", family: ".SF NS Display", path: "SFNSDisplay-Heavy.otf")
    internal static let regular = FontConvertible(name: ".SFNSDisplay-Regular", family: ".SF NS Display", path: "SFNSDisplay-Regular.otf")
  }
  internal enum ZapfDingbats {
    internal static let regular = FontConvertible(name: "ZapfDingbatsITC", family: "Zapf Dingbats", path: "ZapfDingbats.ttf")
  }
}

Usage example

swift

// You can create fonts with the convenience constructor like this:
let displayRegular = UIFont(font: FontFamily.SFNSDisplay.regular, size: 20.0)
let dingbats = UIFont(font: FontFamily.ZapfDingbats.regular, size: 20.0)

// Or as an alternative, you can refer to enum instance and call .font on it:
let sameDisplayRegular = FontFamily.SFNSDisplay.regular.font(size: 20.0)
let sameDingbats = FontFamily.ZapfDingbats.regular.font(size: 20.0)
