What is the best way to implement the design?

Question

Swift

There is a design idea, in finished form it +- looks like this:
There are three buttons and an inscription:

When you click on the "add icon" button (select an icon), a UIImageView appears, with the selected icon: The

question is:
How to add this UIImageView , if the entire design is built on AutoLayout (and spacing between elements is also specified)?
I understand that if you initially add a UIImageView, and just put isHidden, then the user will see an empty space.
Remove spacing at the place of adding the image, and register, given the new UIImageView ?
PS
in my design, not only a new UIImageView appears after selection, but a whole UIVIew, with new elements:
it was:

it became:

where to put the old buttons? just .removeFromSuperview()?

Answer 1

Alternatively, redesign. In modern applications, they show the default icon and, usually, clicking on it opens the icon change flow.
If you somehow do what you described, then you can put a UIImageView right away, just without a picture. As a result - until the picture is set, the element will collapse; when the picture is installed - appears.

Answer 2

Use a StackView, put the necessary elements there that you want to "collapse" if they are without data.
