I found that error causes when device lost connection for a moment. it's happen when you have damaged (or very old) cable. How ironic... trying to connect a device for ones for been wireless anymore, but cable...
我发现该错误导致设备暂时失去连接。当您损坏（或非常旧）的电缆时会发生这种情况。多么具有讽刺意味......试图连接一个设备，因为它不再是无线的，但是电缆......

All I did was unplug the charger from the phone and replugged it back in. This solved it for me.

There might be more than one reason for this error:
导致此错误的原因可能不止一个：
"An error was encountered while attempting to communicate with this device. (The service is invalid.)"
“尝试与此设备通信时遇到错误。（服务无效。）”
I hit this problem today after I transferred my iPad XCode project from one Mac to another. I was pretty sure there was nothing wrong with my USB cable, it was working just fine on the other Mac with the same iPad.
在我将 iPad XCode 项目从一台 Mac 转移到另一台后，我今天遇到了这个问题。我很确定我的 USB 电缆没有任何问题，它在使用相同 iPad 的另一台 Mac 上运行良好。
So I did the old XCode standby voodoo solution:
所以我做了旧的 XCode 备用 voodoo 解决方案：
- in XCode, do a
Product->Clean Build Folder; - quit XCode;
- from the macOS Finder, delete the
DerivedDatafolder for the project; - launch XCode, rebuild and run.
- 在 XCode 中，做一个
Product->Clean Build Folder; - 退出 XCode；
- 从 macOS Finder 中，删除
DerivedData项目的文件夹； - 启动 XCode，重建并运行。
It works just fine now.
它现在工作得很好。
