default.realm 数据到领域同步/云

如何解决default.realm 数据到领域同步/云

我的应用是免费增值类型，用户可以免费使用该应用，但仅限离线使用，所有数据都存储在 default.realm 文件中。

一切正常，但当用户想要与其他设备同步时，他们需要订阅提供的订阅。

这给我带来了一个问题，当用户支付订阅费用时，应用程序将执行 sync.configuration 到 realm.Configuration，但是一旦完成，应用程序中显示的所有数据在更改时都无法查看

问题：如何执行上传/请求realm云来同步default.realm中的所有数据？

*** 领域配置 ***

class RealmManager {
    static let shared = RealmManager()
    let realmApp = App(id: "xxxxxxxxxx")
    
    lazy private var realmURL: URL = {
        return Realm.Configuration.defaultConfiguration.fileURL!
    }()
    
    lazy private var config:Realm.Configuration = {
        return Realm.Configuration(
        fileURL: self.realmURL,inMemoryIdentifier: nil,syncConfiguration: nil,encryptionKey: nil,readOnly: false,schemaVersion: 1,migrationBlock: nil,deleteRealmIfMigrationNeeded: false,shouldCompactOnLaunch: { totalByte,usedByte in
            let twentyMB = 20 * 1024 * 1024
            return (totalByte > twentyMB) && (Double(usedByte) / Double(totalByte)) < 0.6
        },objectTypes: nil
        )}()
    
    func realm(config:Realm.Configuration? = nil) -> Realm {
        let user = realmApp.currentUser
        var realm = try! Realm()
        
        if ((user?.isLoggedIn) != nil) {
            let partitionValue = user!.id

            if realm.objects(usermodel.self).first != nil
                && realm.objects(usermodel.self).first?.typeID == UserType.Premium.rawValue {
                print("online user with sync config")
                realm = try! Realm(configuration: (user?.configuration(partitionValue: partitionValue))!)
            } else {
                print("online user without sync config")
                realm = try! Realm(configuration: self.config)
            }
        }
        else {
            print("no sync config")
            realm = try! Realm(configuration: self.config)
        }
        return realm
    }
    
}

/// InAppPurchase: User completed transaction,perform sync to realm cloud
let user = RealmManager().realmApp.currentUser
let configuration = user?.configuration(partitionValue: user?.id ?? "")
_ = RealmManager().realm(config: configuration)
                                

This is the error Code i received after perform /// InAppPurchase: User completed transaction,perform sync to realm cloud

All processes sharing a single file must be the same architecture. 
For sharing files between the Realm browser and an iOS simulator,this means that you must use a 64-bit simulator.
