I'm getting this issue too. Your edit was very helpful for me. Actually, the file app is in "./data/Containers/Shared/AppGroup/(File App?)/File Provider Storage/". Just make some uniq folder on File app, and search with find . -type d -name "(folder name you created)". Add some file in this directory will adds that file in the simulator too.

In iOS 18.1, textSelection(_:) works in List! https://stackoverflow.com/a/79135453/11073133 Thank you so much! I was working on enabling text copying in my app and spent hours wondering why .textSelection(.enabled) wasn’t working. However, thanks to your post, I realized that the issue was due to testing on the iOS 18.0 simulator. I tested it with the iOS 18.1 simulator, and it was solved beautifully. Without your post, I would have spent several more hours struggling. I sincerely appreciate it from the bottom of my heart.
