我得到这个错误：致命错误：索引超出范围。我无法得到我做错了什么。我试图做的是，通过使用访问数组字典整数索引比传递一个字符串来获取映射到它的值。示例在操场上工作正常，但不能解释为什么？ （数组字典不为空） 
这里是我的代码致命错误：索引超出范围
var CondoIndivi2 = [[String:AnyObject]]()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
scrollView.contentSize.height = 1500
print(CondoIndivi2)
if let description_Condo = self.CondoIndivi2[0]["description"] as? String {
print(description_Condo)
}
}

'self.CondoIndivi2'最初是空的。你有没有把东西放进去？ – BallpointBen
我刚刚编辑了这个问题。是的，我发送数据给它使用prepareforsegue –
你认为可能是什么问题？ –
