iOS/tvOS游乐场失败，“无法为选定的运行目标找到执行服务”
iOS/tvOS游乐场失败，“无法为选定的运行目标找到执行服务”
提问于 2015-10-23 20:45:27
在迁移到XCode 7.1之后，我不能在iOS和tvOS平台上使用游乐场。只有OS能工作。最简单的操场代码生成错误消息：
无法为选定的运行目标找到执行服务
我怀疑这与XCode没有找到合适的模拟器有关，但是我不知道在哪里以及如何配置它。
我在现有的项目中尝试了游乐场，以及刚刚创建了一个从飞溅屏幕。
有什么可能是错的吗？

检查控制台提供了更多的洞察力，但仍然不清楚如何修复：

好吧，经过一番挣扎，这是解决办法。
- 清除文件夹
~/Library/Developer/CoreSimulator - 重新启动机器
- 尝试运行一个iOS游乐场，它现在应该可以正常工作了。
注意:在我的例子中，将CoreSimulator重命名为CoreSimulator.old，重新启动后自动创建了一个新的CoreSimulator (因此，我丢弃了.old one)。
顺便说一句，这里有一个文件~/Library/Developer/CoreSimulator/Devices/device_set.plist，在/Root/DefaultDevices下面有一个完整的模拟器列表。我认为这就是问题的根源。

也许有一个更快的解决办法：
检查Xcode中的设备中是否有iPad Pro模拟器。如果没有-通过添加模拟器选项添加它。
正如一些人在评论中所指出的，您可能还需要重新启动Xcode或重新打开操场。
若要添加模拟器，请转到设备(窗口>设备)。单击窗口左下角的+按钮，单击“添加模拟器”，然后从下拉列表中选择适当的"Device“，然后单击"Create”。

我能够用终端中的以下两个命令来解决这个问题：
$ rm -rf ~/Library/Developer/CoreSimulator/Devices
