I am so glad we sticked to Objective-C++ and UIKit. After reading all the comments here, it looks like SwiftUI will take another 2 years to stabilize.

Yeah. You could start introducing some Swift now for new code but I’d stay well clear of SwiftUI outside of widgets.

The main problem with Objective-C++ is that only us old timers still have documentation available.

Most newcomers won't even know it exists.

Objective-C on UIKit in 2020?! You should absolutely be using Swift for all new UIKit view controllers, note that SwiftUI is not a requirement for usage of swift.
