我在
Xcode 6 for iOS 8模拟器中运行应用程序时遇到错误.该错误指出“无法在当前状态下启动设备：正在创建”.我试图重置模拟器的内容.此外,我在安装Xcode 6后重新启动了mac.可能有什么问题？
解决方法
当我将Xcode应用程序从’Xcode 2.app’重命名为’Xcode6.app'(我安装了5& 6 Xcodes)时,我遇到了这个问题

You will need to delete this device from your simulator and recreate it.
From inside the iOS Simulator application menu,choose Hardware > Device > Manage Devices
In the Simulators list on the left,select the device that is unable to boot and press the delete key
Now use the + in the bottom left to add a new device with the same hardware / OS configuration.
