Firebase Ep.3: Database Persistence (Xcode 9 Swift 4 iOS 11)

Today's video I have talked about how simple it is to store cache of the Firebase Database, in case the user goes offline, they still can access to the cached database, then read and write data into the database as usual.

Just get started by typing this after the FIRApp.configure() line in the didFinishLaunchingWithOptions method in the AppDelegate Class:

// Import Statements
import FirebaseDatabase

// Code
FIRDatabase.database().persistenceEnabled = true
