问题描述
自从更新到Xcode 6.1后，一段时间后Mac将无法识别我的所有iOS设备。它曾经是每两天，但现在每天都会发生几次。
Since updating to Xcode 6.1 all of my iOS devices will not be recognized by the Mac after a period of time. It used to be every couple of days, but now it is happening several times a day.
唯一的办法就是重启Mac。这是完全不可接受的，并且与任何基于UNIX的操作系统相反。在安装Yosemite之前，我已经运行了同样的Mac几个月，没有问题。
The only remedy is to reboot the Mac. This is completely unacceptable and counter to any UNIX based OS. I have run this same Mac for months before installing Yosemite, without issue.
唯一的线索是在系统日志中：
The only clue is in the System logs:
12/22/14 8:42:53.681 PM Xcode[385]: AMDeviceConnect (thread 0x128e11000): Could not connect to lockdown port (62078) on device 67 - 28cb21671799bc4efe266987ae586ba2cb6247b7: 0xe8000084.
我已经在网上搜了好几个星期甚至提交了雷达。我知道其他开发者经历过这种荒谬的行为。有没有人知道发生了什么或服务失败了什么？
I have scoured the web for weeks and even filed a radar. I know that other devs have experienced this ridiculous behavior. Does anyone have a idea what is going on or what service is failing?
当前正在运行OS X 10.10.1，Xcode 6.1.1并且iOS 8.1.2会出现问题，iOS 8.1和iOS 7.1.2
Currently running OS X 10.10.1, Xcode 6.1.1 and issues occur with iOS 8.1.2, iOS 8.1 and iOS 7.1.2
推荐答案
我已经有这个问题已经有一个多月了。它不仅仅是Xcode，还有iTunes，Image Capture和其他一些应该可以轻松查看我的设备的应用程序。我也经常得到信任这台电脑？查询，但不是每次Mac开始拒绝我的设备。
I've been having this issue for over a month now. It's not just Xcode but also iTunes, Image Capture, and some other apps that should easily see my devices. I also often get the "trust this computer?" query, but not every time that the Mac starts rejecting my devices.
除了重启Mac，另一个选择是退出Xcode，在终端发出以下命令：
Instead of restarting the Mac, the other option is to quit Xcode, issue the following command in Terminal:
然后重新启动Xcode
and then restart Xcode
