How to make a target extension via xcodegen ?

[Simimi-dot]

My question is as follows. How can I create an extension target through xcodegen?
I need to create a Notification Service Extension target, but I don't quite understand how this can be done correctly through xcodegen, since when I create this target through Xcode itself, a folder with the NotificationService.swift and info.plist files for this target is automatically created. And this does not happen through xcodegen.
Since there is no such target yet, I cannot specify a source for it.
I can separately create a folder in which info.plist and entitelements were created using xcodegen, but the NotificationService.swift file will not be created.
Does anyone know how to do this?

• you have to add target config for your extension as well in the project.yml used by xcodegen
• Apart from the main App target, you can create other extension targets the following way

Example:

targets:
    NotificationService:
      type: app-extension

Please don't forget to mention type: app-extension.
Refer section Product Type from docs
