I added custom font to a framework. I followed all the steps, but it doesn\'t work.

I am able to set the font in Interface Builder, but when I build the project it d

Swift 4:

This is maybe an old thread but has updated @xaphod for swift 4 as all static and global variables are lazily initialised using dispatch_once.

extension UIFont {

// load framework font in application
public static let loadAllFonts: () = {
    registerFontWith(filenameString: "SanFranciscoText-Regular.otf", bundleIdentifierString: "Fonts")
    registerFontWith(filenameString: "SanFranciscoText-Medium.otf", bundleIdentifierString: "Fonts")
    registerFontWith(filenameString: "SanFranciscoText-Semibold.otf", bundleIdentifierString: "Fonts")
    registerFontWith(filenameString: "SanFranciscoText-Bold.otf", bundleIdentifierString: "Fonts")
    registerFontWith(filenameString: "SanFranciscoText-LightItalic.otf", bundleIdentifierString: "Fonts")
}()

//MARK: - Make custom font bundle register to framework
static func registerFontWith(filenameString: String, bundleIdentifierString: String) {
    let frameworkBundle = Bundle(for: MSAlertController.self)
    let resourceBundleURL = frameworkBundle.url(forResource: bundleIdentifierString, withExtension: "bundle")
    if let url = resourceBundleURL, let bundle = Bundle(url: url) {
        let pathForResourceString = bundle.path(forResource: filenameString, ofType: nil)
        if let fontData = NSData(contentsOfFile: pathForResourceString!), let dataProvider = CGDataProvider.init(data: fontData) {
            let fontRef = CGFont.init(dataProvider)
            var errorRef: Unmanaged? = nil
            if (CTFontManagerRegisterGraphicsFont(fontRef!, &errorRef) == false) {
                print("Failed to register font - register graphics font failed - this font may have already been registered in the main bundle.")
            }
        }
    }
    else {
        print("Failed to register font - bundle identifier invalid.")
    }
}
}

Then you can call UIFont.loadAllfont inside the appDelegate
