Oh... Well, that definitely shouldn't have happened.

Must note that may be cases when App Playgrounds built with Xcode won't run in Swift Playgrounds, and the other way around (for example, see this thread). Check if your app runs fine on Swift Playgrounds on macOS.

Perhaps the thread allows only Apple-employee accounts to comment

It seems that it doesn't work on other browsers either.

Yeah, same for me. There's no Reply textbox.

Weird... For me, on Safari (macOS) it does't work either (tried private browsing window too). The Reply and Add a Comment buttons are there but they don't do anything when clicked.

I was going to make a new post about this, but fortunately I found this thread. It seems that the less-than sign is still not fixed, but I think you know that :) Maybe this happens within some kind of cross site scripting protection? Just a guess...

No problem! Yeah, I figured out maybe that's what happened. For a moment, I read it that way too :)

i'm not Quinn, but I'd say what I think. The expression is a closure passed in the set: parameter of the initialiser. You need to pass a closure that takes a newValue parameter (of the T type as in Binding, which here is Bool) as input, and set it to whatever other variable you use. You use another variable to store the binding's actual value, and this value is of type MyBool.

NavigationView is deprecated. You can use NavigationStack and NavigationSplitView instead. Here you can find more details.
