This morning I have updated my Xcode 9 beta 1 to Xcode 9 beta 6. I'm working with ARKit and my application works fine on beta 1 but now, when I run my app I got this error: 

//
//dyld: Symbol not found: _OBJC_CLASS_$_ARConfiguration
//Referenced from: /var/containers/Bundle/Application/5B74AF4C-011C-45B0-8BAD-DEF3DA7C0DFA/testARKit.app/testARKit
//Expected in: /System/Library/Frameworks/ARKit.framework/ARKit in /var/containers/Bundle/Application/5B74AF4C-011C-45B0-8BAD-DEF3DA7C0DFA/testARKit.app/testARKit
//

It's a SIGABRT on my thread 1

0 __abort_with_payload

-> 0x102ba1774 <+8>: b.lo 0x102ba178c <+32>

5 _dydl_start

-> 0x102b751e0 <+68>: mov x16, x0

Let me know how to fix this bug.

Clean your project: shift + option + cmd + k, then remove your derived data and rebuild project.

  • That doesn't work for me. I have the same issue except the symbol not found is "_OBJC_CLASS_$_ARWorldTrackingSessionConfiguration" – Alain Berrier Sep 16 '17 at 11:59

    That's exactly the update that creates the problem. I tried with iPad 5 after updating to iOS 11, I got the error. I tried with iPhone 7 on iOS 11 beta 4 or 5, same code, no issue. I updated it and I got the error. – Alain Berrier Sep 16 '17 at 18:10

There is API change in beta version. Please update Xcode 9 (beta) to Xcode 9 and iOS 11 (beta) to iOS 11. It works for me.
