iPhone不可用.请重新连接设备. /iOS 14.2-Xcode 12.1 [英] iPhone is not available. Please reconnect the device. / iOS 14.2 - Xcode 12.1
问题描述
我刚刚将iPhone更新为iOS 14.2.
I just updated my iPhone to iOS 14.2.
当我想从Xcode在设备上启动应用程序时，现在看到的内容如下:
When I want to launch an app on the device from Xcode, I now keep seeing this:
我还刚刚将Xcode更新到版本12.1，希望它可以解决问题，但是没有什么区别，我一直收到相同的消息.
I also just updated Xcode to Version 12.1, hoping it would solve the problem, but it doesn't make any difference, I keep getting the same message.
很明显，我尝试断开并重新连接设备，但无济于事.
Obviously I tried disconnecting and reconnecting the device, but to no avail.
我还删除了〜/Library/Developer/Xcode/DerivedData/下的所有数据，但同样没有效果.
I also removed all the data under ~/Library/Developer/Xcode/DerivedData/, but again with no effect.
似乎其他人以前也遇到过这个问题，但是我没有找到任何可行的解决方案.
It seems like some other people have had this issue before, but I didn't find any working solution for me.
我希望最近有类似经历的人能为我指出正确的方向，以找到解决此问题的正确方法.
I hope someone with a recent similar experience can point me in the right direction for a proper way to solve this problem.

And just copy and paste unzipped folder by path:
Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/-
重新启动Xcode
Restart the Xcode
仅此而已.您可以构建并继续您的项目:)

为什么要执行这些步骤? :因为Xcode 12.1不包含对14.2的支持，所以我们为14.2实现了其设备支持文件.
Why we have done these steps ? : Because Xcode 12.1 doesn’t include support for 14.2 so we implemented its device support files for 14.2.
