For me I had to take a closer look at each of the views I was trying to show in the TabView. I was testing the functionality of the TabView, as I am new to this, and found that each view I wanted to add to the tabview had to also be in a view.

For example, I could not have a home page with just a text element and a spacer. They need to be in a VStack or HStack to make the TabView display properly.

This would have all been a non-issue is had built out the page before trying to create a TabView...
