WatchOS未在Xcode 7中的运行目标中列出

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demo watchOS 2应用程序。我无法让它在模拟器中运行，因为watchOS模拟器未在运行目标中列出。

在本教程中，运行目的地显示为否则：

我已经厌倦了可以在互联网上找到的任何可能的解决方案。

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）。

感谢。

检查日志，看起来CoreSimulator无法与设备建立连接。

这里是system.log：

Answer 1

这通常表明Xcode.app无法与CoreSimulatorService进行通信。 Xcode 6.x中存在很多问题。在7.0中进行了改进，但仍有一些情况可能会遇到问题。

如果您遇到这样的问题，最简单的方法就是使用大锤并重新启动。

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

如果重启后仍有问题，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。这是输出：

$ xcrun simctl list

    iPhone 6 (21272670-640D-436E-8DD4-F4014D2F63DC) (Booted)

== Device Pairs ==

由于某些我不知道的原因，Xcode 7和Simulator无法正确识别和设置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

这创建了一个新的配对设备ID：

$ xcrun simctl list

    Phone: iPhone 6 (21272670-640D-436E-8DD4-F4014D2F63DC) (Booted)

现在，我已创建了一个设备对并已连接。回到Xcode，我在运行目的地列出了配对设备：
