iOS模拟器仅显示空白屏幕

Question

我已经将我的几个macminis升级到El Capitan 10.11.2并安装了Xcode 7.1。但iOS模拟器显示出一些问题。比如，Xcode 7.1的默认iOS是9.1，当我从SDK 9.1在iOS模拟器中启动任何设备时，它只是向我显示黑屏。

所以要检查一下，我去了Xcode＆gt;首选项和下载的SDK 9.0和8.4。当我从SDK 9.0或8.4切换到任何设备时，它们工作正常。但我不知道它的默认SDK 9.1会发生什么。

我在下面尝试了解决问题的方法。

1. 重新安装Xcode。
2. 重置设备内容。
3. 在SDK 9.1下再次删除了设备文件夹和已创建的设备。
4. 删除并重新创建/ private / tmp /并拥有正确的权限。
5. 更多。

他们都没有工作。

当我切换到SDK 9.1下的任何设备时，我已经粘贴了一些CoreSimulator.log日志。

Answer 1

退出xcode并杀死pid并关闭并退出模拟器。 再次午餐xcode并转到窗口 - ＆gt; divices - ＆gt;删除所有设备并添加它，它将起作用。
