Apple Watch App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苹果手表应用程序，它有两个界面控制器。

当我部署到手表模拟器时，一切都按预期工作。但是，自从更新到Xcode 7，iOS 9和WatchOS2 GM种子后，该应用程序不再运行在物理苹果手表上。它将启动，显示加载屏幕约10秒，然后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
• 尝试从Xcode部署后多次重新启动应用程序，以确保Xcode不仅因为某些原因而无法启动。
• 仔细检查每个接口控制器
上是否正确设置了类和模块
• 确保iOS应用，Watch App和Watch App Extensions plist文件具有WKAppBundleIdentifier，WKCompanionAppBundleIdentifier等的正确值。
• 仔细检查我的WatchKit扩展程序中的所有文件是否具有正确的目标成员资格

此时我真的没想到了。我的猜测是，有一些明显的简单事情我一定做错了，但我看不出来。

我已经解决了这个问题。应用程序无法启动的真正原因是因为它没有足够快地启动，因此守护程序终止了该进程。我的三个采摘者中的每一个都试图按顺序加载~20张图像。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。
