I’m currently developing a multiplatform app and am having issues with both the tab control and sidebar on the iPhone and iPad devices. Ideally I want the user to be able to switch between the two if they prefer one over the other... and the switching currently works great but I've noticed minor issues with both formats.

Specifically my app can go up to four levels but in this sample I have three. The left sidebar or tabs has four choices, the middle has it's own choices, and the right has a text box showing what was clicked on. With the sidebar option I notice the right screen doesn't change when you click on the sidebar (though the center does). Also the sidebar clicks print out text (with the onChange modifier) but don't register in the view.

I was going to lock it down to just tab control for now so the app is easily useable but noticed if you click to the third level then switch tabs the back button on the phone changes (from saying back) to reflect the newly selected tab but the content shows the old view.

Using tab control on the iPad the middle sidebar (now on the left side)updates when the tab is changed but again, like with the phone, the right pane shows the old content.

Just curious if anyone knows of a good multiplatform SwiftUI tutorial that would help me get this working. In my actual app the right view sometimes has two levels with a back button.

Either way hope your day is going good!
