WatchOS未在Xcode 7的运行目标中列出

Question

我按照本教程（http://code.tutsplus.com/tutorials/create-a-native-apple-watch-app-for-watchos-2--cms-24201）创建了一个演示watchOS 2应用程序。由于watchOS模拟器未列在运行目标中，因此无法在模拟器中运行。

在本教程中，运行目标出现了，否则：

我与任何可能的解决方案，我可以在互联网上找到耗尽。

我错过了什么？或者，这是Xcode的问题吗？

我在OS X 10.10.5上运行Xcode 7（7A220）。

谢谢。

UPDATE：

经过日志，它看起来像CoreSimulator不能让与设备的连接。

这里SYSTEM.LOG：

Answer 1

这通常表明Xcode.app不能与CoreSimulatorService沟通。在Xcode 6.x中有很多这样的问题。 7.0中有所改进，但仍有一些情况下可能会遇到问题。

如果你有这样的问题，最简单的做法是使用大锤子并重新启动。

1. 请勿重命名Xcode.app，因为这是进入此状态的主要原因。
2. 如果您确实重命名Xcode.app，请重新启动以进入干净状态。

如果重启后仍然有问题，可能会提示〜/ Library/Logs/CoreSimulator/CoreSimulator.log和/var/log/system.log中出现了什么问题。

Answer 2

我使用终端命令xcrun simctl解决了这个问题。这里的输出：

$ xcrun simctl list 

== Device Types ==

iPhone 5 (com.apple.CoreSimulator.SimDeviceType.iPhone-5)

-- watchOS 2.0 -- 
== Device Pairs == 

由于某些原因，我不知道，Xcode 7和模拟器不能识别和正确设置watchOS 2.0设备。

$ xcrun simctl create "Apple Watch 38mm" com.apple.CoreSimulator.SimDeviceType.Apple-Watch-38mm com.apple.CoreSimulator.SimRuntime.watchOS-2-0 

输出：

EF648CAD-2C4B-4BD5-9C36-9D1DB3E3CD29 

然后，

$ xcrun simctl boot EF648CAD-2C4B-4BD5-9C36-9D1DB3E3CD29 

$ xcrun simctl pair EF648CAD-2C4B-4BD5-9C36-9D1DB3E3CD29 21272670-640D-436E-8DD4-F4014D2F63DC 

这创造了一个新的配对的设备ID：

现在，我已经创建了一个装置对和连接。回到Xcode和我在运行目的地列出的配对设备：
