Just provide Swift 4 fix to @gebirgsbärbel answer. "preferredContentSizeCategory" in Objective-C is a method, but in Swift it is a read-only variable. So in your AppDelegate is like this:

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    // MARK: - UIApplicationDelegate

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {

        UIApplication.classInit

        self.window = UIWindow(frame: UIScreen.main.bounds)
        ...
        self.window?.makeKeyAndVisible()
        return true
    }
}

// MARK: - Fix Dynamic Type

extension UIApplication {

    static let classInit: Void = {
        method_exchangeImplementations(
            class_getInstanceMethod(UIApplication.self, #selector(getter: fixedPreferredContentSizeCategory))!,
            class_getInstanceMethod(UIApplication.self, #selector(getter: preferredContentSizeCategory))!
        )
    }()

    @objc
    var fixedPreferredContentSizeCategory: UIContentSizeCategory {
        return .large
    }
}
