What happened to the "Preview Content" folder for new projects? Based on some blog posts, a "Preview Content" folder would automatically be created for a new SwiftUI project. Did this change for Xcode 26? (I'm using Xcode 26.6). It appears I can create a "Preview Content" group manually, but I would need to add "Preview Assets" manually, and update DEVELOPMENT_ASSET_PATHS in the build settings. I selected SwiftUI when creating the project. Thanks.
