Did you find a solution to this? Despite Xcode 13 advertising that it now supports array element binding via `ForEach($model.value) { $values in ...` it is also not working for me.

Here we are a few years later, still cant login to apple developer for more than a few hours...

Can't update my app even with Xcode 13.2.1

The submit issue asside, seems production builds are extremely unstable. I have never seen so many crashes with nonsensical stack traces since we deployed swift concurrency in our retail build. This thing seems to be alpha at most.

It worked for a while, now it is back to being broken... can't submit again.

Apple asleep at the wheel. What else is new.

Have you found a solution for this? Might it just be that the sandbox environment is offline?

Same issue here. I see "Testing..." in the Xcode statusbar but it does nothing. It seems to work when I turn off "Execute in parallel".

I have the same problem with Sonoma / Xcode 15. It's quite annoying since I don't even need anything Metal related.

I refuse to use Feedback Assistant anymore, out of the ~50 issues I filed there exactly 0 where fixed or even replied to. Even some 3 or 4 year old reports are still not fixed and the issue persists to this day.

Found a better way yet? Having the same problem.

Can't say for iOS, but since it shares the same TextKit codebase as macOS, I can say that scrolling performance degrades significantly above ~3000 lines. 10k lines is an absolute nightmare. That being said, it seems to matter if a text view has line wrap or not. If it has no linewrap, the performance is significantly worse - which is ironic since you would imagine the layout can just assume fixed line heights.

I have the same problem with Apples default "SubscriptionStoreView". Did anyone resolve this?
