我的原始应用程序在swift2.3中使用xcode 7正常运行，但在我使用xcode 8转换为swift3.0后，出现了很多错误，然后我解决了所有问题。我运行我的swift3应用程序没有错误，但是！它在着陆页中崩溃，并显示错误消息
线程1：在AppDelegate类中发出SIGABRT信号
当应用程序在swift2.3中运行时，我对解析和核心数据仍然没有问题。 我还尝试其他解决方案，例如1.add all privacy into info.plist files

感谢所有给我建议的人，我终于解决了我朋友教给我的问题。我在这里分享这两个解决方案希望可以帮助其他像我一样面临类似问题的人。
xcode 8 beta有时会错过断点。当我们调试时，我们设置了一些断点，但是xcode并没有停止在我们设置的地方。事实证明错误大约是我们之前设置的断点，但xcode 8 beta并没有就此止步......最终我们使用本土方法逐步测试我的代码。
真正的错误是因为＆＃34;核心数据＆＃34;代码表达式在swift 3.0中被更改，更重要的是，编写核心数据的新方法并不意味着它可以解决这个问题。
例如：
旧路（swfit2.2）： 它会导致xcode出现错误，所以你必须改变它
let fetchRequest = NSFetchRequest(entityName: "Restaurant")
新方式（swift3.0）： 这是我犯的一个关键错误，我跟随别人的建议，改变旧的方式，xcode没有显示错误警告，所以我只是运行应用程序，它崩溃了!!没有任何特定的错误指向这个代码行，并像我说的xcode 8 deta有时无法在断点停止，所以它导致我们找到错误的方式。
let fetchRequest: NSFetchRequest<NSFetchRequestResult> = Restaurant.fetchRequest()
正确的新方式（swift3.0） 当我运行应用程序时，这是没有警告和正常工作的正确方法。
let fetchRequest = NSFetchRequest<NSFetchRequestResult>(entityName: "Restaurant")
所以，这就是我的解决方案，在Apple开发者论坛和一些stackoverflow帖子中，人们都有像我这样的每个类似错误消息，但解决方案都是不同的。祝你好运！

通常，Thread 1: signal SIGABRT错误在末尾有一条消息，带有更多指示。在您的情况下，libc++abi.dylib: terminating with uncaught exception of type NSException。
This SO answer说它可能来自故事板中断开的segue。 有时在迁移期间会发生。你能看看吗？
修改：抱歉，我刚看到您已经对此进行了测试。
