I am still seeing this with Xcode 12.3 on iOS 12.4.1 devices. Anybody find a workaround?

edit: using lipo is necessary, and is the accepted solution for this. Can you provide some links to where this is documented and how we are supposed to accomplish this? I am in the middle of getting some of our C++ dependencies to build with iOS arm64 simulator support and am failing when attempting to make an xcframework with all three slices.
