Ios Springboard意外退出，因为Swift项目为空

我创建了一个新的swift项目，并没有对该项目进行任何更改。这只是一个空洞的swift项目。如果我选择在iphone6上运行，跳板将会崩溃。但是如果我选择其他的（比如iphone5s或可调整大小的iPhone，甚至iphone6plus），空的项目就可以了

有人知道我的xcode出了什么问题吗？我该如何处理这个问题

错误消息太长，我无法将整个消息附加到此处。我会选择一些对我来说很重要的部分

这个问题在我将Xcode更新到最新版本后自动解决了

如果您对该问题有可能的答案，我们仍然欢迎您回答该问题。

在您的项目中，搜索setObjectForKey，或搜索创建带有键和对象的字典的代码，记录键。您好，我搜索了整个项目，但没有找到它：（Xcode引导我找到名为AppDelegate.swift的文件，并显示“Thread 1:signal SIGTERM”。AppDelegate.swift文件是自动生成的。
