Answer 1

Most Of the Time this happened to me when a design change is being called for INFINITE time. Which function can do that? well it is this one:

override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
    }

Solution is to add condition where the function inside of viewDidLayoutSubviews get calls only 1 time.
