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

in firebase •  7 years ago 


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

Hey, my name is M3, and I'm giving you an upvote, and a subscribe. Me and my community of followers are trying to kill YouTube, and make DTube bigger and better than any other video site. YouTube doesn't reward creators like they deserve, so we're all helping each other out. Anyway, keep going! What we're doing really is the way of the future.``

Thanks for the upvote and subscribe without watching a second of the video! I was affected by the YPP policy change so I ditched YouTube and moved onto DTube. I'm still new to here and trying to host the IPFS node but it seems that it's not working right now. Note that this is the reupload of my YouTube video.
