@martinmitrevski I can probably revert this, since it is not related, but this means that for simulators, the loading view will never appear, and while doing development this can be annoying, especially because most devs initially use the simulator to test things.

Ideally, in the future we should try to follow the Thread List v2 approach, where when there is already a cache, and the data is loading, we show a loading spinner in the header view. As well, as a loading spinner on the footer view when loading more data. (This useful especially in low network conditions)

why not update this logic for simulators only? (Keep everything as is for regular devices)

That is going to complicate the code IMO. I think we should align this with UIKit, besides that it is usually not a good practice using network reachability for things that can potentially block user interaction 🤔

ok, if it's this way on UIKit, let's keep it like this.

loading = channels.isEmpty

controller?.synchronize { [weak self] error in
guard let self = self else { return }
