The solution as you've mentioned and I forgot to applied, was change these compilation flags and distribution options: Build Settings / deployment / oAlways Embed Swift Libraries = Yes Build Settings / deployment / strip swift symbol = No Also when uploading : unselect 2 first options about BitCode and Strip Swift Symbols At this answer https://developer.apple.com/forums/thread/715162?answerId=728753022#728753022 By the way, with the changes, works even with xCode 13.4.1. Thank you so much

Thank you for the help. We have performed the archive/distribution with xCode 13.4 and 13.2.1, but the same result :-( Termination Reason: DYLD 4 Symbol missing Symbol not found: __swift_FORCE_LOAD_$_swiftFoundation Referenced from: /Volumes/VOLUME/*/Primax Go.app/Frameworks/IBMMobileFoundationSwift.framework/IBMMobileFoundationSwift Expected in: /System/Library/Frameworks/Foundation.framework/Foundation

Thank you so much for the info, we'll test with xCode 13.4 and post the results.
