更新 Xcode 后的 EXC_BAD_ACCESS (SIGABRT)

Question

在我将 Xcode 从 9.4 和 Command Line Tools(macOS High Sierra version 10.13) for Xcode（6 月 18 日更新）更新到 9.4.1 之后，当我提交我的应用以供审核时，我总是收到以下错误。

我已经尝试了我在网上找到的任何东西：

1. 删除obj和bin目录
2. 从头开始重新创建 LaunchScreen.storyboard。
3. 将所有库更新到最新版本
4. 重新安装VS
5. 重新安装 Xcode

我在我的应用程序中使用以下库：

1. 谷歌注册
2. xamarin 身份验证
3. ff图像加载
4. newtonsoft.json

我的 Visual Studio 是最新版本，这是我的发布设置：

我在模拟器和 iPhone 7 上从未发生过这种崩溃。 有没有想法我做错了什么？

Answer 1

目前的VS 2017 mac有一个奇怪的bug；当我打开我的故事板时，它将作为 iPhone 8 plus 板打开。当我将其更改为 iPhone 4s 时，有时它会删除特定 UITableView 的名称。这导致Null pointer exception。

我不知道为什么 VS 会这样做，但这是我的问题的根源。

顺便说一句，仅当我的构建配置为 Debug/Release - iPhone 时才会发生。
