after updating Xcode 13.2.1 (13C100) when I run my app on iPhone 6(12.5.5) it's showing an error and the app is crashing.

    dyld: Symbol not found: ___chkstk_darwin

  Expected in: /usr/lib/libSystem.B.dylib

  • This is not a solution but note that the error explains that "libswift_Concurrency.dylib (which was built for iOS 13.0)", but you're running the app on iOS 12.5.5, so it's not super surprising that some function definitions may be missing. What is your deployment target version? – Itai Ferber Feb 09 '22 at 15:55
  • Keep using XCode 13.1 for running on iOS 12.X safely – Larme Feb 09 '22 at 15:59
  • deployment target version is 12.3 – PK Chahar Feb 09 '22 at 16:24
