Swift provides the following UIStackView function to insert a view at a specified position:

func insertArrangedSubview(_ view: UIView, atIndex stackIndex: Int)

(see the documentation for more information)

You need to use

func insertArrangedSubview(_ view: UIView, at stackIndex: Int)

like that:

stackView.insertArrangedSubview(view3, at: 3)
