在Swift中执行事务时如何读取Theo从Neo4j返回的数据？

Question

我在Swift中有一个iOS应用程序，使用Theo与Neo4j数据库集成。我想从数据库中读取数据，所以我正在执行这样的事务：

let createStatement = "MATCH (n:`\(labelName)`) RETURN n"       
let resultDataContents = ["row", "graph"]
let statement = ["statement" : createStatement, "resultDataContents" : 
resultDataContents] as [String : Any]
let statements = [statement]

theo.executeTransaction(statements, completionBlock: {(response, error) in
    print("response: \(response)")
})

这是正确执行的，＆＃34;响应＆＃34;值与数据一起返回，但我不知道如何从中提取我需要的关系和属性。每当我打印＆＃34;响应时，这就是数据的格式化方式。值：

["results": <__NSSingleObjectArrayI 0x60400000f630>(

    columns =     (
        n

这甚至是什么样的物体？如何提取我需要的数据和值？我迷失了。非常感谢任何帮助或见解。
