Same question. I tried using SF Symbols as normal text characters. They appear fine when you place them in your code, but in the app they display as question marks inside a square.

Xcode 14.0.1. Same problem. I wrote the project a year ago, and now (Oct, 2022) I can't even preview any SwiftUI code. The project builds and runs without any problems though.

Still a problem of having appear to have current date filled in when in fact the value is "". Don't know about other stuff. But originally I found this page while looking into the issue of not submitting the form on Enter/Return.
