Same issue Xcode 15 Beta 6. App works in simulator but crashes on real device

I'm also having the same issue on Xcode 15 beta 6 on macOS Ventura on an iOS 17 device running beta 6.

From the release notes:

Known Issues: Apps using SwiftData that are built with Xcode 15 beta 6 have known issues when running on iOS 17 beta 6. (113915428): Workaround: Use iOS 17 Beta 5 with Xcode Beta 6.

Correct me if I am wrong, but I dont think we can easily downgrade in IOS, so I will be waiting for Beta 7 of Xcode.

This issue is fixed for me on beta 7 of iOS 17 and Xcode 15.

I'm getting same issue on Beta 5 and Beta 7

If you upgrade to Sonomo 14.0 Beta (23A5328b) it fixes the problem

Hi,

I'm getting the same issue:

dyld[927]: Symbol not found: _$sSo24OS_dispatch_queue_serialC8DispatchE5label3qos10attributes20autoreleaseFrequency6targetABSS_AC0E3QoSVAbCE10AttributesVSo0a1_b1_C0CACE011AutoreleaseJ0OANSgtcfC

  Expected in:     <5D28AD50-9087-35F4-B443-436779FBCC38> /usr/lib/swift/libswiftDispatch.dylib

I'm running Sonoma 14.0 Beta (23A5312d), and Xcode 15.0 beta 8.

I wondered if this is because of some of my libraries I'm using, but I've re-added all my deps using spm again, and still experiencing this.

This is my bt dump:

* thread #1, stop reason = signal SIGABRT
  * frame #0: 0x00000001cfcecee4 dyld`__abort_with_payload + 8
    frame #1: 0x00000001cfcf6bcc dyld`abort_with_payload_wrapper_internal + 100
    frame #2: 0x00000001cfcf6bfc dyld`abort_with_payload + 12

    frame #5: 0x00000001cfc9c2e0 dyld`start + 1760

Thought to provide it here just in case it's of any help to someone.
