swift - Apple Watch 应用程序在模拟器上运行，但不在物理设备上运行

Question

我正在开发一个相对简单的 Apple Watch 应用程序，它有两个界面 Controller 。

当我部署到 watch 模拟器时，一切都按预期进行。但是，自从更新到 Xcode 7、iOS 9 和 WatchOS2 GM seed 后，该应用程序不再在实体 Apple Watch 上运行。它将启动，显示加载屏幕约 10 秒，然后崩溃并在设备日志中显示以下消息:

我尝试过的事情:

• 多次删除并重新安装应用
• 尝试在从 Xcode 部署后多次重新启动该应用程序，以确保它不仅仅是 Xcode 由于某种原因未能启动。
• 仔细检查每个接口(interface) Controller 上的类和模块是否正确设置
• 确保 iOS 应用、Watch 应用和 Watch 应用扩展 plist 文件具有正确的 WKAppBundleIdentifier、WKCompanionAppBundleIdentifier 等值。
• 仔细检查我的 WatchKit 扩展中的所有文件是否具有正确的目标成员资格

在这一点上我真的没有想法了。我的猜测是我一定做错了一些明显的简单事情，但我就是看不到它。

我已经解决了这个问题。该应用无法启动的真正原因是它启动速度不够快，因此守护进程终止了该进程。我的三个选择器中的每一个都试图加载约 20 张图像以按顺序使用。这对于模拟器来说很容易处理，但对于物理设备来说太过分了。
