Swift Realm的響應結果不同

Question

let syncServerURL = URL(string: serverUrl + "Combine")! 
var configuration = Realm.Configuration() 
configuration.encryptionKey = Utility().getKey() as Data 
configuration.syncConfiguration = SyncConfiguration(user: SyncUser.current!, realmURL: syncServerURL) 

Realm.asyncOpen(configuration: configuration, callback: { realm, error in   
    if let realm = realm { 
     let results = realm.objects(Combine.self) 
    } else if let error = error { 
     print("error ******* \(error)") 
     // Handle error that occurred while opening or downloading the contents of the Realm 
    } 
}) 

我使用此asyncOpen方法配置來獲取同步的領域，響應結果顯示爲與領域服務器記錄相同。

let syncServerURL = URL(string: serverUrl + "Combine")! 
var configuration = Realm.Configuration() 
configuration.encryptionKey = getKey() as Data 
configuration.syncConfiguration = SyncConfiguration(user: current, realmURL: syncServerURL) 
let realm = try! Realm(configuration: configuration) 
let results = realm.objects(Combine.self) 

我用得到同步領域，響應結果沒有顯示一樣的境界服務器記錄此方法配置。它顯示不正確/過時的記錄

上述結果是不同的

asyncOpen()從服務器下載調用回調之前所有的變化，而同步構造函數立即返回本地領域實例，並在後臺同步。這意味着不能保證數據是最新的。
