Symbol not found Crash Error (swiftui sdk)

Sendbird Chat UIKit iOS
1

[Problem/Question]
App crashes immediately on launch due to a missing Swift runtime symbol when using SendbirdSwiftUI SDK.
The issue occurs on real devices (I have tested on iPhone 13 and iPhone 14 Pro Max), and appears to be related to SendbirdUIMessageTemplate.framework referencing an unresolved symbol in SendbirdChatSDK.framework.

Iā€™m working with SendbirdDesk and SendbirdChat, and Iā€™m getting the exact same issue. The app works fine when running on a simulator but crashes immediately when running on a physical device..with the exact same missing symbol output.
Did you ever find a solution to this??

I contacted Sendbird support.
They confirmed it was an ABI compatibility issue with the Sendbird SwiftUI SDK.

The fix has already been released ā€” please update to the latest version (1.1.1):
tag 1.1.1

After updating, the issue was resolved on my side. :white_check_mark:
