Swift edition for undocumented font change:

extension NSObject {

    class func objectClassName() -> String {

        let classLongName = reflect(self.self).summary;

        let tokens = classLongName.componentsSeparatedByString(".")

        if let typeName = tokens.last {

            return typeName
        }

        return NSStringFromClass(self.dynamicType)
    }
}

func changeSectionIndexFont(tableView: UITableView) -> Void {

        let realSubviews = tableView.subviews as! [UIView]

        for subview in realSubviews {

            if subview.dynamicType.objectClassName() == "UITableViewIndex" {

                subview.setValue(UIFont(name: "OpenSans", size: 10), forKey: "font")
            }
        }
    }
