Hello,
Welcome to our Microsoft Q&A platform!
I am following a tutorial in youtube and the guy opens Storyboard designer in Visual Studio (Open storyboard designer)
Starting with Visual Studio 2019 version 16.8 and Visual Studio for Mac version 8.8, the recommended way to edit .storyboard and .nib files is by editing them in Xcode Interface Builder on a Mac, we cannot open Storyboard designer in Visual Studio, we have to use Visual Studio for Mac and the Xcode Interface Builder to continue building your Xamarin.iOS
user interfaces.
Please see this official article about it, and it provide step by step way to edit .storyboard
by editing them in Xcode Interface Builder on a Mac
