Xcode Project won't run on iOS Device
提问by Amit Kalra
Xcode gives me this message every-time I try running my app on my iPhone. (Works fine on the simulator.) (And this occurs in every project I have.) (I also just downloaded Xcode again.)
每次我尝试在 iPhone 上运行我的应用程序时，Xcode 都会给我这条消息。（在模拟器上运行良好。）（这发生在我拥有的每个项目中。）（我也刚刚再次下载了 Xcode。）
This is the message I get.
这是我得到的消息。
App Installation Failed.
Unknown Error Occurred.
How do I fix this error?
我该如何解决这个错误？

Unplugging iOS Device and plugging it back it in fixed it for me.

Alright, it was a simple fix:
好吧，这是一个简单的修复：
Go into Xcode Preferences -> Accounts -> More Info. Hit the refresh icon.
Clean your project. Project -> Clean.
Force quit Xcode.
Reboot Mac and Device.
进入 Xcode Preferences -> Accounts -> More Info。点击刷新图标。
清理你的项目。项目 -> 清洁。
强制退出 Xcode。
重新启动 Mac 和设备。

If you have the same App but downloaded from AppStore, I suggest to remove the App manually from your device, then try to run the new version with XCode.
如果您有相同的应用程序但从 AppStore 下载，我建议您从您的设备手动删除该应用程序，然后尝试使用 XCode 运行新版本。

After following the suggestions in this thread (restarting iPhone, cleaning Xcode project, quitting and re-launching Xcode) and others (setting Team to None then back to my Team) and unplugging and replugging Lightning connector from my iPhone 6 I was still experiencing this problem. Xcode would even display an error that my iPhone 6 was locked, even though it was not.
按照此线程中的建议（重新启动 iPhone、清理 Xcode 项目、退出并重新启动 Xcode）和其他人（将 Team 设置为 None 然后回到我的团队）并从我的 iPhone 6 拔下并重新插入 Lightning 连接器后，我仍然遇到这个问题问题。Xcode 甚至会显示我的 iPhone 6 被锁定的错误，即使它没有。
I was able to fix it by unplugging the USB-A connector of the USB to Lightning cable from my MacBook Pro, then plugging it back in. I'm not sure why that made the difference, but glad that it did resolve this annoying problem.
我能够通过从我的 MacBook Pro 上拔下 USB 转闪电连接线的 USB-A 连接器，然后将其重新插入来修复它。我不知道为什么会有所不同，但很高兴它确实解决了这个烦人的问题.

I have this issue regularly. There are a number of techniques that help me overcome it, including the classic "turn it off and back on again."
我经常遇到这个问题。有很多技巧可以帮助我克服它，包括经典的“关闭并重新打开”。
One thing that isn't mentioned here is that the iPhone should be switched on, unlocked, connected to the mac and then the app should be run (with the iPhone unlocked). Don't lock it!
这里没有提到的一件事是 iPhone 应该打开、解锁、连接到 Mac，然后应用程序应该运行（iPhone 解锁）。不要锁！
