Could someone at Apple please verify that these symbols are available for Xcode to download? This seems to be a recurring issue and really puts a dent in development.
Could not download and install Symbols for watchOS 7.6.1 (18U70). Failed to download package from ADC.
fortunately or unfortunately , we have a thread going with the same issue, hopefully they make it available soon.
these will be fixed shortly, apologies for the inconvenience.
