使用Xcode 9和iPhone 7更新ios11.1

Question

I was testing my application on my iPhone 7 with Xcode9beta6. All was ok when I got an iOS 11.1 update on my iPhone. Now, when I run my project, I have this message :

I tried with the last Xcode9 version too but still this message. Any idea ?

Answer 1

I ran into this yesterday. The issue was I had upgraded to iOS 11.1 Beta on my device (iPhone 6S) but I was using the production version (non beta) of Xcode 9. This version of xCode 9 does not support iOS 11.1 Beta.

I had two options - upgrade my xCode 9 to the latest beta version or go to the backup of my iPhone and restore iOS 11.0.1.

I restored to iOS 11.0.1 successfully and now XCode works fine with the iPhone.

Hope that helps

Answer 2

我也面临同样的问题。这是因为iOS 11.1升级因为Xcode 9 doest支持iOS 11.1 Beta问题已被提出。只有选项可以恢复到旧版本，或者使用与Xcode9兼容的其他设备进行测试

Answer 3

11.1 XCode 9不支持iOS Beta版升级您的XCode 9.1
