Xcode13.2.1 Swift Concurrency cause crash in iOS 12

dyld: Symbol not found: ___chkstk_darwin

  Referenced from: //app.app/Frameworks/libswift_Concurrency.dylib (which was built for iOS 13.0)

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

 in //Frameworks/libswift_Concurrency.dylib

Same issue on my end as well but running it on xcode 13.2 is working without any crash. Any clue ?

I have the same issue when building to an iPhone 6 from Xcode 13.2.1

use "await " which from libswift_Concurrency.dylib, cause crash on ios11 and 12,working well on iOS13

downgrade any library which supported concurrency

Same thing just found for me too. Downgrading to Xcode 13.1 fixed it for me. Hope they fix Xcode, cause I dislike being behind the curve...

please fix this issue as soon as posible, I am amost be fired!

Xcode 13.3 beta 1 has a fix for the crash.

We need an extra fast solution. Our apps build with the Xcode 13.2 and 13.2.1 crashes on the iOS 12.x We have production apps that stopped working on the customer's devices!.

Same here, production app is crashing because of this reason. Customers are waiting for a fix. Installing a beta is too risky for a production app.

Furthermore, I believe this issue might be because of updated RealmSwift lib. Many of us here might be facing this issue because of this.
