Not possible to use Realm in an iOS Messages extension?

Question

需要明确的是，当前无法使用Realm在iOS应用程序和Messages扩展之间拥有单个共享数据库吗？

Answer 1

It is very much possible

For Swift 3

I used the following code to share Realm db between app and app extension:

let sharedDirectory: URL = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.your.app")! as URL
let sharedRealmURL = sharedDirectory.appendingPathComponent("db.realm")
Realm.Configuration.defaultConfiguration = Realm.Configuration(fileURL: sharedRealmURL)

Just call this code from didFinishLaunchingWithOptions of AppDelegate and viewDidLoad of MSMessagesAppViewController
