I’m encountering an issue since I started using Xcode 16. I have a widget in my app, and I'm trying to organize the code by splitting it into different files for better structure.

However, when I do this, I get an error:

error: Unexpected input file: /Users/******/Desktop/TestApp/TestAppWidget/Provider.Swift (in target 'TestAppWidgetExtension' from project 'TestApp')

I want to emphasize that if I keep all the code in one file, everything works fine.

I've checked the Target Membership, and it's set up correctly.

but I don't understand why this is happening only in Xcode 16.

Has anyone else experienced a similar issue or has any ideas on why this is occurring? I would appreciate any help!

Is the error due to Swift suffix instead of swift ?

Try to rename

TestAppWidget/Provider.Swift

to

TestAppWidget/Provider.swift

Have you checked your build phases as well to make sure there are no issues?

Also perhaps deleting the file reference in Xcode and re-adding it may help.

I want to clarify that this issue only occurs in Xcode 16. Everything worked fine in version 15. The problem happens both in my existing project and even if I create a new, completely clean project.
