Hello there. I have a Mac Studio M1 Ultra and a Mac Mini M1, both were unable to packaging iOS app. Which indicated that the UnrealPak-BuildSettings.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64.
After doing some search on Google, there’s no similar result. And I try to rebuilt the UE4, but there only one build target in UE4 which is Rosetta.
the logs are the errors while packaging:
