Google couldn't find this! The device itself is working happily, I can even launch and use the app I'm trying to install. iTunes looks like it's still connected... What could be the problem?
谷歌找不到这个！设备本身运行良好，我什至可以启动和使用我正在尝试安装的应用程序。iTunes 看起来仍处于连接状态...可能是什么问题？

Are you using some "cheap" USB cable? This was the cause in my case.
您使用的是“便宜”的 USB 数据线吗？这就是我的原因。

Just got the same message. I fixed it by connecting my iPhone directly to my Macs USB-Port instead of connecting it to a USB-Hub.
刚刚收到同样的消息。我通过将 iPhone 直接连接到 Mac 的 USB 端口而不是将其连接到 USB 集线器来修复它。

I was having the same issue, and it was due to having old WiFi connection settings. I just connect new WiFi in both iMac and iPhone. I never connect via USB. iMac automatically connects to my iPhone and I can debug directly on my iPhone. Sometimes the connection is loose; in that case, I just go to

Received this message recently and tried the steps above, specifically different combinations of restarting the iPhone, disconnecting/reconnecting it, and quitting/restarting Xcode.
最近收到此消息并尝试了上述步骤，特别是重新启动 iPhone、断开/重新连接和退出/重新启动 Xcode 的不同组合。
In the end, I restarted my comp and it works fine now.
最后，我重新启动了我的电脑，现在它运行良好。
