When creating a new Swift file inside a Swift Package, Xcode skips the filename prompt and generates an empty file without a header. This breaks consistency across projects and slows down development.

This custom file template restores the filename dialog and adds a standard header comment to new Swift files inside Swift Packages.

1. Copy the Swift Package File.xctemplate folder to: [path_to_Xcode]/Contents/Developer/Library/Xcode/Templates/File Templates/MultiPlatform/Source.
2. Restart Xcode.

1. Try to create new File.
2. Choose Swift Package File.
3. Enter the desired filename and location inside your Swift Package.
4. A new Swift file will be created with the standard header.

Happy coding! 🚀
