ios - iOS Realm 迁移内存泄漏

Question

我在使用 Realm (v1.0.2) 迁移期间遇到内存泄漏。我的代码如下所示:

        let config = Realm.Configuration(
        schemaVersion: 1,
        migrationBlock: { migration, oldSchemaVersion in
            // We haven’t migrated anything yet, so oldSchemaVersion == 0
            if (oldSchemaVersion < 1) {
                migration.enumerate(MyClassRealm.className(), { (oldObject, newObject) in

                    newObject!["remoteId"] = 0
                    newObject!["deleted"] = false
                    newObject!["dirty"] = true
                    newObject!["updated"] = 0
                })
            }
    })

    // Tell Realm to use this new configuration object for the default Realm
    Realm.Configuration.defaultConfiguration = config

    // Now that we've told Realm how to handle the schema change, opening the file
    // will automatically perform the migration
    do {
        let _ = try Realm()
    } catch {
        TSLog.error(error as NSError)
    }

堆栈跟踪:

你知道出了什么问题吗？

Answer 1

如果没有堆栈跟踪中间帧的符号，很难判断，但我怀疑您遇到了 Realm Cocoa issue #2933 ，这似乎是由于 Swift 运行时库中的错误而导致的内存泄漏。
