本地存储或 Swift 中的 firebase

Question

I want to make an app with storage but this Information should be shared to other users in real time. For example one could belong to many different groups and when something relative to one group changes every member must receive a notification but also each member should access to all relative Group data (statistics, etc.) Should I Go with coredata and some way of sending messages, or should I choose firebase for all kinds of data? Any ideas would be appreciated

Answer 1

I would implement Firebase SnapshotListener for that while keeping all information in Firebase so you will avoid some sync issues. Look at this link for how to "Get realtime updates with Cloud Firestore", also do not forget to check corresponding Google video with some more explanation on how it works and why single "source of truth" is important for you.
