SwiftUI is still relatively young and... idiosyncratic. I hate how hard or weird it makes some basic things. (empty, transparent element with an action attached just to handle an event of the window appearing?) But there are some really good systems available. .NET WPF is great overall for example. I could of course complain about how things are implemented and how mvvm is not baked in and how converters are too big and many other details. But I never needed to hack around the declarative part - that always just worked.
