[英]Unable to determine simulator device to boot. - Xcode
I just downloaded Xcode 6 & played with it a bit. 我刚刚下载了Xcode 6并且玩了一下。
After switching back to previous version of Xcode and running in simulator, I keep getting this error. 切换回以前版本的Xcode并在模拟器中运行后,我不断收到此错误。
Unable to determine simulator device to boot. 无法确定要启动的模拟器设备。
How do we resolve this? 我们如何解决这个问题?
Thanks in advance. 提前致谢。
确保Dock中只运行一个iOS模拟器实例。
There was a simple answer to this for me: 对我来说有一个简单的答案:
I've faced same issue and solved by below steps: 我遇到了同样的问题,并通过以下步骤解决:
1) Move
xcode6-beta into application folder 1)
Move
xcode6-beta Move
到应用程序文件夹中
2) Restart
mac and open xcode6-beta from application folder. 2)
Restart
mac并从应用程序文件夹中打开xcode6-beta。
I had the same problem when running from Xcode 6 beta selecting iPhone 5s. 从Xcode 6 beta选择iPhone 5s运行时遇到了同样的问题。 If I choose iPhone 5 or "resizable iPhone" then my app launches fine.
如果我选择iPhone 5或“可调整大小的iPhone”,那么我的应用程序启动正常。
You will not see the profiles of simulator without a rebooting of OS XI added simulator for many times,when the rebooting finished, it shows on the device list under the simulator bar. 如果没有重新启动OS XI添加模拟器多次,您将看不到模拟器的配置文件,当重新启动完成时,它显示在模拟器栏下的设备列表中。 I think this is a bug of Xcode 6 Beta
我认为这是Xcode 6 Beta的一个错误
I think you have 2 simulator running in the dock. 我想你在码头上运行了2个模拟器。 Please close another one simulator and run the project again.
请关闭另一个模拟器并再次运行该项目。 It might helpful for you.
它可能对你有所帮助。
In my case I had such a message just because the simulated device was still booting (longer than usually, I guess). 在我的情况下,我有这样的消息只是因为模拟设备仍在启动(我想比通常更长)。 Xcode 7.2.
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)
(这实际上并不是这个具体问题的答案,但我来到这里谷歌搜索标题中的信息,所以我在这里写我的笔记,如果其他人得到了与我相同的情况)
My case wasn't about having two simulators open. 我的情况不是要打开两个模拟器。 It was just because having instruments open as well.
这只是因为打开乐器。 Closing Instruments resolved the issue
关闭工具解决了这个问题
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。
