SwiftUI iPad app has no fullscreen - left and right are black borders

Hi,

I develope an iPad app with AppDelegate to have the ristriction with landscape.

Now, I found out that my app is nothing fullscreen on the newest iPad Air as well in the simulator.

What did I'm wrong or is it normal?

Many thanks in advance. Sven

Top and bottom are ok

Does no one have any ideas or know what I did wrong?
