Opinions please.

I want to share a small model in my iOS app. Now on android I'd do with with ViewModelProviders, but on iOS I'm going with SharedDataContainer which is basically a singleton class that store key value data.

Is there any better approach? Data will not be bigger than 10 list items with guid (key) and int (value)

However; when I have big data I do cache on disk or hello OOM exceptions (or whatever they call that bitch on iOS)
