ios – 在Guard语句swift中提供一个ViewController

guard let statusCode = status else {
        DispatchQueue.main.async() {
            let initViewController = self.storyboard!.instantiateViewController(withIdentifier: "SignInViewController")
            self.present(initViewController, animated: false, completion: nil)
        }
            return
    }

我想知道这是否是最好的做法,因为在呈现一个viewcontroller之后返回并没有多大意义,但是在guard语句中需要它,因为guard语句不能通过.

func yourFunc() {
    guard let statusCode = status else {
      return DispatchQueue.main.async() { [weak self] _ in
        let initViewController = self?.storyboard!.instantiateViewController(withIdentifier: "SignInViewController")
        self?.present(initViewController!, animated: false, completion: nil)
    }
  }
}
