"a Sheet is a modal presentation, its content are presented in a separate mode that prevents interaction with the parent view..." Thank you, @DTS Engineer. That is essentially the "magic" difference I'm looking for. Having read and processed the linked HIG page, if I still wanted to provide a navigation experience inside of an overlay or other custom component, is there public API I can use to achieve that "separate mode", similar to how a sheet does?

I inspected the .xcscheme file of my Xcode 14 project in question and did not see any key named OS_ACTIVITY_MODE.

Hi Quinn. No that works fine. It seems that it's broken for projects that were created with an Xcode version < 15.

Note I regularly see folks wrap the log so that they can add #file and #line markers. There’s no need to do that, because you can get that info using --source. Where can I learn more about --source? I've not heard of this before?
