I'm trying to select a default account number from a list of available accounts. The data is from an FMDB data selection. I've created a test view with two types of pickers in it. One that lists the accounts I've retrieved into an array of data records which is a swift struct. The other picker is one that comes from an on-line example to select colors. The colors "selection" bound value updates as expected, but the "selection" bound value that I set does not change when one of two accounts is presented and selected. Below is the code from my test view that compiles and runs. When I select either account value which is [12345678] or [12345679] which appear as two rows in the picker the selection binding value doesn't change. But for the colors selection value it updates. I'm pretty confused here...

The struct for the accounts record is:

Consider this code:

I have this little example app, that works as expected.
The Textfields an the YellowTextfield get the focus in the expected order.

If I add a .cornerRadius(5.0) th the Textfield of YellowTextfield, the focusorder changes.
Now the YellowTextfield gets the focus on start.

Why does this happen and how can I prevent this?

I don't understand why picker view doesn't work. I used this code:

import SwiftUI

I get this error every time I launch a secondary picker.
The first picker works okay.
However when I switch pickers & scroll, I get the following:

Here is my entire code (written as a test of this problem):
