XCode 7.0.1 显示已下载 8.4 模拟器，但在下拉列表中不可用

Question

XCode 7.0.1 显示已下载的 iOS 8.4 和 8.3 模拟器。但是 iOS 8.4 模拟器无法在下拉菜单中创建新的模拟器实例。

iOS 8.3 模拟器按预期工作。

我想重新下载这个模拟器，看看它是否能正常工作。

我在 XCode 6 中发现了类似的情况，但这些解决方案似乎不适用于 XCode 7.0.1。

iOS 8.3 模拟器运行良好。

"xcrun simctl list"

Answer 1

也许可以从 apple.com 中 dmg 文件的位置尝试：

http://devimages.apple.com/downloads/xcode/simulators/com.apple.pkg.iPhoneSimulatorSDK8_4-8.4.1.1435785476.dmg

Answer 2

在此处发布步骤以防其他人遇到类似问题并将其标记为已回答。

iOS8.4.simruntime 文件 /Library/Developer/CoreSimulator/Profiles/Runtimes.

中有一个零字节

删除该文件启用了从 Preferences/Downloads 屏幕重新下载 8.4 模拟器的选项。但是，通过此操作创建的模拟器报告为 8.4，但实际上是 9.0

使用 XCode/Window/Devices 屏幕删除所有模拟器，然后重新启动计算机，以便能够创建正确版本的模拟器。
