一旦与 Xcode 断开连接，应用程序将不会 运行
App wont run once disconnected from Xcode
我的应用程序在连接到 Xcode 时运行正常。 （我使用的是 Xcode 10.1）
但是，一旦我断开设备并再次启动应用程序（通过点击图标），启动画面就会出现并且应用程序会关闭。这不是真正的崩溃，因为应用程序在有线连接时工作正常。我还在我的应用程序中集成了 Crashlytics，并且它的仪表板上也没有崩溃。
我尝试过的事情：
- 清理并构建代码。
- 重启设备。
- 转到 window -> 设备和模拟器并尝试检查设备
日志（如
所建议的那样），但我在那里没有找到任何东西。

我认为这与 Starscream Websocket 库的使用and/or 设备的网络连接有关。
虽然设备在模拟器中是 运行，但它使用您的 Mac(Book/Pro/etc) 的网络连接；当它自己是 运行 时，它使用设备的 wifi/cellular 连接。
因此，我认为由于设备连接，您将面临一些高延迟。
- 检查网络连接
- 尝试禁用（评论）Starscrem 用法并检查应用程序是否正在启动
- 检查 UI 在显示任何内容之前是否正在等待网络数据
在启动画面的代码中，我试图访问方案集的环境变量，我在这些方案的基础上设置了一些视图。当设备用电线连接时这些变量是可访问的，但当设备未连接时返回 nil （如果有人能解决这个问题，我将不胜感激）
因此，为了解决这个问题，我删除了方案并改为创建目标，设置自定义标志（以我之前使用环境变量所做的工作为基础），然后按照 this 问题的第二个答案中所述访问它们。
