14. DVTBezelAlertPanel class func swizzleMethods() { guard let originalClass = NSClassFromString("DVTBezelAlertPanel")

    as? NSObject.Type else { return } do { try originalClass.jr_swizzleMethod("initWithIcon:message:parentWindow:duration:", withMethod: "xmas_initWithIcon:message:parentWindow:duration:") } catch { Swift.print("Swizzling failed") } }
