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 ?

I don't have this issue in iPhone6 + Xcode 9. – Robinia

Questions seeking debugging help ("why isn't this code working?") must include the desired behavior, a specific problem or error and the shortest code necessary to reproduce it in the question itself. Questions without a clear problem statement are not useful to other readers. See: minimal reproducible example In addition, Do not post images of code or errors – Right

Sorry, that's my first question there. It isn't a code problem but a problem with Xcode and iOS11.1. I thought the screenshot of the error would be more explicit. – Whippoorwill

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
