iOS Debug Symbols - DSYM files not in archive

I’ve posted about this before. I am desperately trying to track down a random crash bug, but I can no longer get Xcode to include the dsym file in the archive - which makes it near on impossible to work out where the crash is happening, or the chain of events leading to it.

The DSYM file is generated in the build folder but just not included in the archive. I had it working last year, but it’s no longer working.

Surely someone mush have this working - if so, could you point me to ALL the settings required to make it work.

Debug Information Format = DWARF with DSYM File
Strip Debug Symbols During copy = NO
Strip Linked Product = NO
Generate Debug Symbols = YES
