Abort trap: 6 error in XCode 12.2

I am using Zoom iOS SDK v5.2.42037.1112 with SwiftUI in XCode 12.2. While compiling it, I am receiving this error:

Any solution?

Hey @zishanj

Thank you for using the dev forum!

That is very interesting. This happens at compile time? Is there any specific code that causes this to appear/disappear or does this happen after you have simply imported the frameworks?


I have downloaded ios-mobilertc-all-5.2.42037.1112-clientlog.zip and copied the lib files into xcode. Then I tried to design layout in SwiftUI and while previewing it in simulator I get this above reported error.

Hey @zishanj,

I am sorry this is happening, that must be frustrating to get this error in the preview. Unfortunately, the SDK is not yet fully integrated with SwiftUI. If you can reproduce this issue outside of SwiftUI we can investigate further, but support for SwiftUI is currently limited.

I will let you know when that changes though.
