The process to reproduce:

1. Create a new extension with Xcode 16 beta.
2. Run it on the simulator or any iOS device with iOS 18 beta installed.
3. Open Safari on your Mac, then open Develop -> Device that you are using.
4. Unable to access these menus for iOS 18:
   1. Extension – Extension Background Content
   2. Extension – Extension Pop-up Page – popup.html
5. However, for iOS 17.4, I can see these options in Develop -> Device iOS(17.4).

Can anyone help resolve this issue?

I have another extension on the App Store that is not working on iOS 18 beta, but I am unable to debug it because of this issue.

I tried running the existing code in iOS 18 beta and also created a new sample project to run on iOS 18 beta. In both scenarios, I was unable to debug the Safari extension.
