I have the same "[API] cannot add handler to 3 from 3 - dropping" message in my App, but I am working in SwiftUI. It looks like my problem is caused by each view which contains a "NavigationView". Changing the NavigationView to a NavigationStack solves the problem. I do not know the equivalent in UIKit. Hopes this will get someone on the right track.
