UI bug

[emelyanovkirill]

iOS 12.5, iPhone 6.
When I set backgroundColor, for instance, in cell bind(to:) method, it act after reuse cell. It can be fix, if to wrap in DispatchMain.async. But on iOS 13 all work without wrapper. I have read, that it is because conflict when change UI properties before view did layout view.
What's the best practice here? Thanks.
