Do you know if there's a way to adjust the width of the button when it's in the expanded state (or just style it in general)? I can't seem to make it work.

I still think it would be helpful if Apple provided a clearer way to incorporate frequent actions into the tabview. As you pointed out, some tabs focus on search — but others might center around a different primary action. It’d be great if the UI could support that more directly.

That's a helpful insight - thanks for taking the time to educate me on this topic ✌️

Thanks, your solution worked :-) It might not be the intended use of .tabViewBottomAccessory, but it looks and feels great in this context

Thanks. I’ve updated my bug report to include a sysdiagnose log from the development Mac, taken right after reproducing the issue in iOS Simulator. I've also included a project that reproduces the issue. FB number: FB18304716
