I can accomplish a full-width button with the following code:

Button {
  print("Test, 123 ...")
}
label: {
  Text("Trigger Action")
  .frame(maxWidth: .infinity)
  .frame(height: 50)
  .background(Color.blue)
  .foregroundStyle(Color.white)
  .cornerRadius(12)
}

It works fine.

But why “maxWidth: .infinity”?

Why isn’t it “minWidth: .infinity”? That would make more sense to me.

Can someone explain, how the .frame-modifier works internally? And why it works the way it does
