Hi all, I apologize for the delays in fixing this. We think we have a fix which is as follows:

open the iOS project/workspace project file
select the application target on the left side of the project filee
go to the Build Settings tab
toggle Levels on
search for Library Search Paths
double click the project level text box that applies to both build configurations
remove "(PLATFORM_NAME)" (NOTE: not the .../lib/swift/... entry; that's the one that's needed!)
We've tested this on our minimal project that reproduced this issue, and archiving was successful, with the default React Native 0.63 project (and a blank Swift file and bridging header).

Please let us know if this works, and if this does NOT work, please file a ticket with your CSM so we can diagnose your specific setup.

Lastly, I'd like to add my personal apology; I was the primary driver of trying to solve this issue, and any delays were purely on me, not anyone else at Iterable.
