swift - xCode 11.2.1-Swift 5-无法将主故事板“ Main”更改为另一个故事板“ Start”(xCode 11.2.1 - Swift 5 - Can't change main storyboard “Main” to another storyboard “Start”)

Question

I have created a new storyboard named "Start.storyboard", but when I change Main Interface to "Start" nothing happened, The app just started with default storyboard "Main.storyboard".

(我创建了一个名为“ Start.storyboard”的新情节提要，但是当我将主界面更改为“开始”时，什么都没发生，该应用程序仅从默认情节提要“ Main.storyboard”启动。)

I'm using xCode 11.2.1 and iOS 13.2.3

(我正在使用xCode 11.2.1和iOS 13.2.3)

Also I have tried to change the rootViewController from (AppDelegate) didFinishLaunchingWithOptions as the code below:

(我也试图从（AppDelegate）didFinishLaunchingWithOptions更改rootViewController为以下代码：)

    let sb = UIStoryboard(name: "Start", bundle: nil)
    let vc = sb.instantiateViewController(withIdentifier: "PhoneVC")
    self.window?.rootViewController = vc

but I got the same result, Main storyboard can't be changed.

(但我得到了相同的结果，无法更改主情节提要。)
