Make sure you have only one iOS Simulator instance running in the Dock.
确保 Dock 中只有一个 iOS 模拟器实例正在运行。

There was a simple answer to this for me:
对我来说，有一个简单的答案：
- Open the simulator via Xcode -> Open Developer Tool -> iOS simulator (even if it can't launch, the app will be open).
- With the simulator app open, go to Hardware -> Device -> Manage Devices.
- Add any missing simulators with the plus button (all of mine were missing for some reason).
- 通过Xcode打开模拟器 -> Open Developer Tool -> iOS模拟器（即使无法启动，app也会打开）。
- 打开模拟器应用程序，转到硬件 -> 设备 -> 管理设备。
- 使用加号按钮添加任何缺少的模拟器（由于某种原因，我的所有模拟器都丢失了）。

You will not see the profiles of simulator without a rebooting of OS X.I added simulator for many times,when the rebooting finished, it shows on the device list under the simulator bar. I think this is a bug of Xcode 6 Beta
多次重新启动OS XI添加的模拟器，您将看不到模拟器的配置文件，重新启动完成后，它会显示在模拟器栏下的设备列表中。我认为这是 Xcode 6 Beta 的一个错误

I think you have 2 simulator running in the dock. Please close another one simulator and run the project again. It might helpful for you.
我想你有 2 个模拟器在码头上运行。请关闭另一个模拟器并再次运行该项目。它可能对你有帮助。

I had the same problem when running from Xcode 6 beta selecting iPhone 5s. If I choose iPhone 5 or "resizable iPhone" then my app launches fine.
从 Xcode 6 beta 选择 iPhone 5s 运行时，我遇到了同样的问题。如果我选择 iPhone 5 或“可调整大小的 iPhone”，那么我的应用程序可以正常启动。

In my case I had such a message just because the simulated device was still booting (longer than usually, I guess). Xcode 7.2. (This is not actually an answer to this specific question, but I came here googling the message in the title, so I am writing my note here for if someone else gets the same case as I did)
在我的情况下，我收到这样的消息只是因为模拟设备仍在启动（我猜比平时更长）。Xcode 7.2。（这实际上不是这个特定问题的答案，但我来到这里是通过谷歌搜索标题中的消息，所以我在这里写下我的笔记，以防其他人遇到和我一样的情况）

My case wasn't about having two simulators open. It was just because having instruments open as well. Closing Instruments resolved the issue
我的情况不是打开两个模拟器。只是因为仪器也打开了。关闭工具解决了这个问题

I just fixed the exact same problem by removing the beta version and rebooting the computer.
我只是通过删除测试版并重新启动计算机来解决完全相同的问题。
