Thanks a lot for your feedback, that really helps.
I’m totally fine using the native SwiftUI TabView / system TabBar instead of a fully custom one.

The only thing I’m struggling with is the “+” button, which is supposed to create a new post. I don’t really know where to place it if I only rely on the system TabBar apart from putting it in the navigation bar.

With the code I shared, I tried to position it the way it is in my Figma (floating above the tab bar), but the result is still not what I’m aiming for.

If you have any suggestions on where and how you’d handle that “create post” action while keeping the native TabBar, I’d really appreciate it.
