  1. Download FontBlaster.
  2. Copy FontBlaster.swift into your project.


Typically, all fonts are automatically found in Bundle.main. Even if you have a custom bundle, it's usually lodged inside of the mainBundle. Therefore, to load all the fonts in your application, irrespective of the bundle it's in, simply call:

FontBlaster.blast() // Defaults to Bundle.main if no arguments are passed

If you are loading from a bundle that isn't found inside your app's mainBundle, simply pass a reference to your Bundle in the blast(_:) method:

FontBlaster.blast(bundle:) // Takes one argument of type Bundle, or as mentioned above, defaults to Bundle.main if no arguments are passed

If you need a list of all of the loaded fonts, an overloaded version of the blast(_:) method has a completion handler that returns just that. Just like the original method, this method takes either a custom Bundle or defaults to Bundle.main if no argument is passed.

// Defaults to Bundle.main as no argument is passed
FontBlaster.blast() { (fonts) in
  print(fonts) // fonts is an array of Strings containing font names

// Custom bundle is passed as argument
FontBlaster.blast(bundle:) { (fonts) in
  print(fonts) // fonts is an array of Strings containing font names

To turn on console debug statements, simply set debugEnabled() = true before calling either blast() method:

FontBlaster.debugEnabled = true

Sample Project

A Sample iOS project is included in the repo. When you launch the app, all fonts are configured to load custom fonts, but don't actually display them until you push the button. After pushing the button, FontBlaster imports your fonts and redraws the view.


This project builds upon an old solution that Marco Arment proposed and wrote about on his blog.
