Unable to prepare iPhone for development

Xcode 真机调试时突然提示：

Please check the connection to the device, and review all errors in the Devices and Simulators window.

打开 Window – Devices and Simulators 面板，看到如下提示：

Failed to prepare device for development.
if youare certain thax xcode supports development on this device, try disconnecting and  reconnecting the device

因为之前就能正常调试的，排除了 Xcode 版本和手机系统版本的兼容问题，也没进行任何更新。

所以只需要 重启手机 即可。
