Memory leak in WkWebView instantiation

Question

I have a Viewcontroller which contains wkwebview when I pop it from the navigation controller I get memory leak

The stack trace leads WkWebview instantiation

I am not using any delegates as well.

I am really wondering what causes this and how to fix this

Answer 1

It is not observed for a long time (at least I can't remember when I met it last time). Just tested in Xcode 11.2 / iOS 13.2. No leaks - neither in simple test project nor in Playground.

Thus, I assume it should be analysed real usage, which introduces leak.
