Unbalanced calls to begin/end appearance transitions for

Question

I have this problem when I simulate my app, its not an error or a warning but it appears in my console, has anyone ever experienced this before?

Answer 1

I had some logic implemented to wait pushing the UIViewController until all data was downloaded. There was an error in this logic which caused to push the UIViewController too early while there was still another API call in progress.

It caused the same UIViewController to be pushed twice by the UINavigationController and gave this warning.
