Hi all, I’ve got a usability question about accessibility navigation. My app has a lot of carousels (horizontally scrolling lists of content with far more elements than can fit on the screen). Often, these are just images, but sometimes, they’re cards with multiple subelements. In our previous implementation, each card was a single accessibility element, and we exposed the subelements as accessibility custom actions. Despite this, users frequently mentioned navigating with VoiceOver as a pain point. It takes a long time to navigate through and navigate past these carousels. To solve this, I converted my carousels into a single adjustable element, so users can navigate through it with one swipe, and they can still access the elements by adjusting the values up and down. I got this advice from this 2018 WWDC talk. Is this still the recommended advice? Or is there a new, preferred way to do this? Additionally, I had to get a little creative with the second carousel, the one with multiple subelements. Some of these were interactive (imagine a card with a description, an upvote button, and a downvote button). Adjustable elements override the accessibility custom actions VoiceOver gesture, so I can’t expose the individual buttons as actions. Instead, I made each subelement in each card in the carousel one of the adjustable values. Swiping up would go from description 1 to upvote button 1 to downvote button 1 to description 2, etc. Double tapping with VoiceOver would perform whatever action the carousel is currently on. So if I adjust the value to the element at index 2 (say, downvote 1), double tapping would trigger the downvote button’s action. Does this make sense? Is there a better way to do this? This seemed to be the best compromise between screenreader navigation speed, exposing all actions, and the existing UI.

I'm trying to compile my project, which worked fine before upgrading to Xcode 16, and I'm getting error clang: error: unsupported option '-mno-thumb' for target 'arm64-apple-ios18.0-simulator'. It appears to a similar issue as this BoringSSL-GRPC issue. The fix from StackOverflow was to automatically strip the flag in the Podfile using CocoaPods, but I'm not using CocoaPods. I've grepped the entire project, and I can't find that flag anywhere in the project. Likewise, the full error message doesn't even include -mno-thumb. Does anyone know how I can determine where this flag is being added, so I can remove it? I've tried this in both Xcode 16.1 and Xcode 16.2 on MacOS Sonoma and Sequoia 15.2.
