Hi, I created an enhancement request number: FB11471366

Many people have reported this and other TextField deficiencies including firstResponder and Next button. Apple needs to address this soon.

I understand my problem. I didn't turn on Mac Catalyst. This misunderstanding happened when I created a new Xcode project and selected iOS and MacOS assuming it would be a Mac Catalyst project with that turned on.

I too am stunned by the lack of support for EditMode on MacOS. I too thought I was doing it wrong. Maybe I still am. Nobody from Apple has bothered to respond to this post or mine from a few days ago. How about a little official guidance Apple?

The doc documentation is wrong. Here is the definition /// The mode of a view indicating whether the user can edit its content. @available(iOS 13.0, tvOS 13.0, *) @available(macOS, unavailable) @available(watchOS, unavailable) public enum EditMode { ..... And the compiler presents an error that it is unavailable.
