Thank you! I confirm that this works!

This is disastrous! we have a highly customized UI in our app, and the floating tab covers the navigation item title!

Yup. There is definitely a bug. This conversation covers it, as well as a reported bug.

I am seeing the same issue in the release iOS18 simulator. Works fine, on-device, and on the iOS17 simulator. The only issue is the iOS18 simulator. I did not test the iOS18 SIMULATOR, because I didn't want to use an unreleased Xcode. I did test on an iOS18 device, though, and that never showed a problem.

I did submit a feedback item on this: FB13787361 I suggested adding a "Sign in with Apple" line to the app's Settings Screen:

Thanks. I had assumed that would be the answer, and I think that I may have come up with an acceptable workaround, but we'll see. You, sir, are an international treasure.

Thanks! That was what I needed.

Same thing is happening to me, but ONLY when compiling for My Mac (Mac Catalyst). It has been working fine, for iOS/iPadOS, for years.

OK. Now this is an answer. It's really, really dumb, and I'm not the dummy. It looks like the documentation screen hangs onto the last filter that was used, so if you (as do I) like to use the Quick Help Navigator, and "Open in Documentation," you'll generally have a value in the "Filter" entry, and the bottom of the Navigator. If there is anything at all in there, it will block display of the documentation. I will register a bug, saying that this should be cleared, when opening as a result of the "Build Documentation" step.

I am posting this as an answer, even though it is just another gripe. The reason is because I can't seem to track my comments; only answers. This is what I posted in a comment, above: Sadly, this does not work for me, and there's absolutely ZERO indication, as to why. Even the sample Apple SlothCreator package example does not work. I am using the latest ship Xcode (13.2.1), and I downloaded the sample (From the page linked with instructions), fifteen minutes ago. I followed the example in this page, verbatim. It simply opens the Apple documentation viewer, with the standard built-in docs. My app's docs are nowhere to be seen. I have been writing frameworks and packages in Swift for years, and documenting with Jazzy, so all my code already has the triple-slash/double-star markdown notation. I can't get documentation to appear for any of my projects (they have all been upgraded to 5.5, for some time). I'm quite sure that I'm doing something wrong, but it is impossible to tell what it is, that I am doing wrong.

I think that this is the answer you are looking for. I have not fully tested it, so far, but it seems to work.

This is a problem for me, as well

Nope. I have a feeling that Apple is abandoning IB, in favor of SwiftUI; which isn't a bad thing, except that I'm not convinced that SwiftUI is up for really big, complex projects, yet.
