Answer 1

After adding anotherImageView as a subview of imageView setup its constraints in the way you want.

So, after this line:

imageview.addSubview(anotherimageview)

Add the following:

anotherimageview.translatesAutoresizingMaskIntoConstraints = false
anotherimageview.centerXAnchor.constraint(equalTo: imageview.centerXAnchor).isActive = true
anotherimageview.centerYAnchor.constraint(equalTo: imageview.centerYAnchor).isActive = true
// And do the same for the width and height constraints.
