迁移到XCode 7.1后，我不能在iOS和tvOS平台上使用Playground。仅OS X有效。最简单的游乐场代码会产生错误消息:
我怀疑这与XCode找不到正确的模拟器有关，但是我不知道在哪里以及如何配置它。
我在现有项目中尝试过游乐场，也只是在启动屏幕中新建了一个。
任何想法可能有什么问题吗？
更新:
检查控制台可以提供更多的见解，但仍不清楚如何解决:

最佳答案
可能有一个更快的解决方案:
检查您的Xcode设备中是否有 iPad Pro模拟器。如果不是，请通过“添加模拟器”选项添加它。
正如一些评论中指出的那样，您可能还需要重新启动Xcode或重新打开游乐场。
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“设备类型”，然后单击“创建”。
