xcode8 list of simulators not showing
提问by Ryan Cocuzzo
I have been only recently working with Xcode 8 beta 4 but it has been working fine up until now. The list of simulators is not showing for any of my projects. I already tried Creating a new Scheme and it did not work. How do I fix this?
我最近才开始使用 Xcode 8 beta 4，但到目前为止它一直运行良好。我的任何项目都没有显示模拟器列表。我已经尝试创建一个新的方案，但没有奏效。我该如何解决？

Deleting derived data and restarting Xcode worked in my case.
删除派生数据并重新启动 Xcode 在我的情况下有效。
rm -rf ~/Library/Developer/Xcode/DerivedData/*

Ensure your Deployment Targetversion in Build Settingsis also set to the desired version (and that you have that version of the respective simulator installed). In the below example, if that were set to 10.3 and I didn't have an iOS 10.3 simulator installed, I wouldn't be able to see any simulators. But because it's set to 10.1, and I have 10.1 simulators installed, I can see them.
确保您的Deployment Target版本Build Settings也设置为所需的版本（并且您安装了相应模拟器的该版本）。在下面的示例中，如果将其设置为 10.3 并且我没有安装 iOS 10.3 模拟器，我将看不到任何模拟器。但是因为它设置为10.1，并且我安装了10.1模拟器，所以我可以看到它们。

If this issue is project - specific, you opened a project which has "Supported platforms" build setting set to iphone or such. Most likely this is due to simulator not having the required capabilities or an embedded library not compiled to run on simulator.
如果此问题是特定于项目的，则您打开了一个将“支持的平台”构建设置设置为 iphone 等的项目。这很可能是由于模拟器没有所需的功能或未编译为在模拟器上运行的嵌入式库。
Change this setting to "iOS" to see the simulators available for running.
将此设置更改为“iOS”以查看可供运行的模拟器。

Set proper deployment target. And also the simulators with greater/same deployment target versions needs to be downloaded.
设置适当的部署目标。并且还需要下载具有更大/相同部署目标版本的模拟器。

Just to make sure, tried sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer, which worked after xcode restart.
只是为了确保，试过sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer，它在 xcode 重启后工作。

In my case, I had to manually add all the emulators again after upgrading to Xcode 8
就我而言，升级到 Xcode 8 后，我不得不再次手动添加所有模拟器

Faced a similar issue with Xcode 8.3.2 (on Sierra) where installed devices were not showing up. Unfortunately restarting Xcode did not work for me but rebooting the machine did. Also answered on Apple developer forum
