ios - 类型 'Any' 不符合协议(protocol) 'Sequence'

Question

我在我的代码中遇到了问题，在尝试解析 JSON 数据(数组的每个数据，比如它应该如何完成)并尝试设置 for in 循环时，错误出现了。这是我的代码

if let jsonDataArray = try? JSONSerialization.jsonObject(with: data!, options: [])
{

    print(jsonDataArray)

    var allStops = [busStops]()

    for eachData in jsonDataArray
                    ^
    //this is where the error is located 

    {

        if let jsonDataDictionary = eachData as? [String : AnyObject]
        {

            let eachStop = busStops(jsonDataDictiony: jsonDataDictionary)

        }

    }

}

直接指定jsonDataArray的类型为[[String: Any]]，这样试试

if let jsonDataArray = try? JSONSerialization.jsonObject(with: data!, options: []) as? [[String: Any]] {
     for eachData in jsonDataArray {
         let eachStop = busStops(jsonDataDictiony: jsonDataDictionary)
     }
}
